Contraceptive methods

The diaphragm is a shallow, dome-shaped cup made of silicone that is inserted into the vagina before sexual intercourse to cover the cervix. It works by blocking sperm from entering the uterus and is typically used in combination with spermicide for increased effectiveness.

Diaphragms come in different sizes and require a prescription and fitting by a healthcare provider. They must be inserted before intercourse and left in place for at least 6 hours after intercourse but no more than 24 hours to prevent infection. Additional spermicide should be applied with each act of intercourse.

With perfect use, the diaphragm is approximately 94% effective at preventing pregnancy. Typical use effectiveness is around 88%, due to issues like incorrect placement, dislodgement during intercourse, or failure to use spermicide consistently.

Common issues with diaphragms include vaginal irritation (particularly from spermicides), urinary tract infections, and difficulty with insertion or removal. Some users may also find the preparation before intercourse to be cumbersome or mood-interrupting.

The diaphragm offers the advantage of being woman-controlled and having no systemic hormonal side effects. It can be inserted hours before intercourse, allowing for some spontaneity, and is reusable for up to two years with proper care. However, it does not protect against sexually transmitted infections and requires a prescription and initial fitting by a healthcare provider.

Cervical Cap

The cervical cap is a small, thimble-shaped cup made of silicone that fits snugly over the cervix. It works by blocking sperm from entering the uterus and is typically used in combination with spermicide for increased effectiveness.

Cervical caps come in different sizes and require a prescription and fitting by a healthcare provider. They must be inserted before intercourse and left in place for at least 6 hours after intercourse but no more than 48 hours to prevent infection. Additional spermicide should be applied with each act of intercourse.

With perfect use, the cervical cap is approximately 91% effective at preventing pregnancy in women who have not given birth vaginally. For women who have given birth vaginally, perfect use effectiveness drops to 74% due to changes in cervical shape. Typical use effectiveness is around 86% for women who have not given birth and 71% for those who have.

Common issues with cervical caps include vaginal irritation (particularly from spermicides), difficulty with insertion or removal, and potential dislodgement during intercourse. Some users may also find the preparation before intercourse to be cumbersome or mood-interrupting.

The cervical cap offers the advantage of being woman-controlled and having no systemic hormonal side effects. It can be inserted hours before intercourse, allowing for some spontaneity, and is reusable for up to one year with proper care. However, it does not protect against sexually transmitted infections and requires a prescription and initial fitting by a healthcare provider.

Contraceptive Sponge

The contraceptive sponge is a soft, disk-shaped device made of polyurethane foam that contains spermicide. It is inserted into the vagina before sexual intercourse to cover the cervix and release spermicide to kill sperm. The sponge works by both blocking sperm from entering the uterus and immobilizing or killing sperm that come into contact with it.

The contraceptive sponge is available without a prescription and comes in one size designed to fit most women. It must be inserted before intercourse and left in place for at least 6 hours after intercourse but no more than 30 hours to prevent infection.

With perfect use, the contraceptive sponge is approximately 91% effective at preventing pregnancy in women who have not given birth. For women who have given birth, perfect use effectiveness drops to 80% due to changes in vaginal and cervical shape. Typical use effectiveness is around 88% for women who have not given birth and 76% for those who have.

Common issues with the contraceptive sponge include vaginal irritation or dryness (from the spermicide), difficulty with insertion or removal, and potential dislodgement during intercourse. Some users may also report a decrease in sexual sensation or find the preparation before intercourse to be cumbersome.

The contraceptive sponge offers the advantage of being woman-controlled, available without a prescription, and having no systemic hormonal side effects. It can be inserted hours before intercourse, allowing for some spontaneity, and provides protection for multiple acts of intercourse within a 24-hour period. However, it does not protect against sexually transmitted infections and may be less effective for women who have given birth vaginally.

Spermicides

Spermicides are chemical substances that immobilize or kill sperm. They come in various forms, including creams, gels, foams, films, and suppositories, and are inserted into the vagina before sexual intercourse. Spermicides can be used alone but are more effective when combined with barrier methods like condoms, diaphragms, or cervical caps.

Spermicides typically contain the active ingredient nonoxynol-9, which works by disrupting the cell membrane of sperm. They must be inserted into the vagina shortly before intercourse (usually 10-30 minutes prior, depending on the formulation) and may need to be reapplied for each act of intercourse.

With perfect use, spermicides alone are approximately 82% effective at preventing pregnancy. Typical use effectiveness is around 72%, due to issues like incorrect application, failure to wait the recommended time before intercourse, or not reapplying for multiple acts of intercourse.

Common issues with spermicides include vaginal irritation, burning sensations, or allergic reactions, particularly with frequent use. Some studies have suggested that nonoxynol-9 may increase the risk of HIV transmission by causing vaginal irritation that facilitates viral entry, though this risk appears to be primarily associated with frequent use (multiple times daily).

Spermicides offer the advantage of being woman-controlled, available without a prescription, and having no systemic hormonal side effects. They can be used in combination with other barrier methods to increase effectiveness. However, they do not protect against sexually transmitted infections and may actually increase the risk of certain infections when used alone and frequently.

Intrauterine Devices (IUDs)

Intrauterine devices (IUDs) are small, T-shaped devices inserted into the uterus by a healthcare provider. They are among the most effective forms of reversible contraception, offering long-term protection against pregnancy with minimal user intervention. There are two main types of IUDs: hormonal and non-hormonal (copper).

Hormonal IUDs

As mentioned earlier in the hormonal methods section, hormonal IUDs release progestin locally, which thickens cervical mucus to prevent sperm from reaching the egg, thins the uterine lining, and may suppress ovulation in some users. They are available in different formulations with varying durations of effectiveness, ranging from 3 to 7 years depending on the brand.

With perfect use, hormonal IUDs are approximately 99.8% effective at preventing pregnancy. Typical use effectiveness is similarly high, as user error is minimal once the IUD is in place. This makes them one of the most effective reversible contraceptive methods available.

Common side effects include irregular bleeding patterns, particularly during the first few months after insertion. Many users experience lighter periods or amenorrhea (absence of periods) over time. Other side effects may include headaches, breast tenderness, mood changes, and ovarian cysts (usually harmless and self-resolving).

The hormonal IUD offers the advantage of long-acting, highly effective contraception that does not require daily attention. It is discreet and not affected by gastrointestinal issues or medication interactions. Fertility typically returns quickly after removal. Like other hormonal methods, it does not protect against sexually transmitted infections.

Copper IUD

The copper IUD is a non-hormonal intrauterine device wrapped in a small amount of copper wire. It works by creating an inflammatory response in the uterus that is toxic to sperm, preventing fertilization. The copper ions also impair sperm motility and prevent implantation should fertilization occur.

Copper IUDs are approved for use for up to 10-12 years, depending on the brand, making them the longest-lasting reversible contraceptive method available. With perfect use, they are approximately 99.2% effective at preventing pregnancy. Typical use effectiveness is similarly high, as user error is minimal once the IUD is in place.

Common side effects include heavier and more painful periods, particularly during the first few months after insertion. Some users may also experience increased cramping between periods. Unlike hormonal methods, copper IUDs do not typically cause systemic hormonal side effects like mood changes or headaches.

The copper IUD offers the advantage of long-acting, highly effective contraception without hormones, making it suitable for women who cannot or prefer not to use hormonal methods. It is discreet and not affected by gastrointestinal issues or medication interactions. Fertility typically returns immediately after removal. Like other non-barrier methods, it does not protect against sexually transmitted infections.

Sterilization Methods

Sterilization is a permanent form of contraception that involves surgical procedures to block or cut the fallopian tubes in women or the vas deferens in men, preventing the egg and sperm from meeting. These methods are intended for individuals who are certain they do not want children in the future.

Tubal Ligation (Female Sterilization)

Tubal ligation, commonly known as “having your tubes tied,” is a surgical procedure that blocks, seals, or cuts the fallopian tubes to prevent eggs from traveling from the ovaries to the uterus. This prevents fertilization and pregnancy. The procedure can be performed in several ways, including cutting and tying the tubes, sealing them with clips or rings, or using electric current to create scar tissue that blocks the tubes.

Tubal ligation is typically performed as an outpatient procedure under general anesthesia, though it can sometimes be done immediately after childbirth or during a cesarean section. Recovery time varies depending on the surgical approach but usually ranges from a few days to a couple of weeks.

Tubal ligation is more than 99% effective at preventing pregnancy, making it one of the most effective contraceptive methods available. However, it is not 100% effective, and there is a small risk of pregnancy, including ectopic pregnancy (pregnancy outside the uterus), which can be life-threatening if not treated.

Potential risks and complications include those associated with any surgical procedure, such as infection, bleeding, or reactions to anesthesia. There is also a small risk of damage to surrounding organs during the procedure. Some women may experience changes in menstrual patterns or develop post-tubal ligation syndrome, characterized by heavy or painful periods, though research on this condition is inconclusive.

Tubal ligation offers the advantage of permanent contraception without the need for ongoing attention or user intervention. It does not affect hormone production or sexual function. However, it is difficult to reverse, and reversal procedures are expensive, not always successful, and may not be covered by insurance. Like other non-barrier methods, it does not protect against sexually transmitted infections.

Tubal Implants (Essure)

Tubal implants, such as the Essure system, involve inserting small, flexible coils into the fallopian tubes through the vagina and cervix without incisions. Over time, scar tissue forms around the coils, blocking the fallopian tubes and preventing pregnancy. The procedure is typically performed in a doctor’s office without general anesthesia.

After the procedure, it takes about three months for the scar tissue to form and completely block the tubes. Women must use alternative contraception during this time and then undergo a confirmation test (hysterosalpingography) to verify that the tubes are fully blocked.

Tubal implants are more than 99% effective at preventing pregnancy when the confirmation test confirms complete blockage. However, some women may experience incomplete blockage or expulsion of the coils, requiring additional procedures.

Potential risks and complications include perforation of the uterus or fallopian tubes during insertion, pelvic pain, and changes in menstrual patterns. There have also been reports of more serious complications, including migration of the coils to other parts of the body and allergic reactions to the nickel in the coils. In rare cases, ectopic pregnancy can occur if the procedure fails.

Tubal implants offer the advantage of permanent contraception without incisions or general anesthesia. Recovery time is typically shorter than with traditional tubal ligation. However, the procedure is not reversible, and there have been concerns about complications leading to the removal of Essure from the market in some countries. Like other non-barrier methods, it does not protect against sexually transmitted infections.

Vasectomy (Male Sterilization)

Vasectomy is a surgical procedure that cuts or seals the vas deferens, the tubes that carry sperm from the testicles to the urethra. This prevents sperm from being present in the semen ejaculated during sexual intercourse, thus preventing pregnancy. The procedure does not affect testosterone production or sexual function.

Vasectomy is typically performed as an outpatient procedure under local anesthesia in a doctor’s office or clinic. The procedure takes about 15-30 minutes, and most men can return home the same day. Recovery time is usually a few days, though strenuous activity should be avoided for about a week.

Vasectomy is not immediately effective, as sperm may remain in the vas deferens beyond the point of sealing. Men must use alternative contraception for about 3 months after the procedure and then undergo a semen analysis to confirm that no sperm are present in the ejaculate. Once confirmed, vasectomy is more than 99.9% effective at preventing pregnancy.

Potential risks and complications include temporary pain, swelling, or bruising in the scrotum, infection at the incision sites, and the formation of sperm granulomas (small, inflammatory lumps caused by leaking sperm). Rare complications include chronic pain, hematoma (collection of blood), and spontaneous reconnection of the vas deferens.

Vasectomy offers the advantage of permanent contraception with fewer risks and complications than female sterilization. It is less expensive and has a faster recovery time. The procedure can sometimes be reversed, though reversal is expensive, not always successful, and may not be covered by insurance. Like other non-barrier methods, it does not protect against sexually transmitted infections.

Fertility Awareness-Based Methods

Fertility awareness-based methods (FABMs) involve tracking a woman’s menstrual cycle to identify fertile days when pregnancy is most likely to occur. Couples then avoid unprotected intercourse during these fertile days or use barrier methods to prevent pregnancy. These methods require commitment, education, and consistent practice to be effective.

Calendar Method (Rhythm Method)

The calendar method, also known as the rhythm method, involves tracking menstrual cycles over several months to predict fertile days. The method assumes that ovulation occurs around 14 days before the start of the next period and that sperm can survive in the reproductive tract for up to 5 days, while the egg remains viable for about 24 hours after ovulation.

To use this method, women record the length of their menstrual cycles for at least 6 months to determine the shortest and longest cycles. The fertile window is then calculated by subtracting 18 days from the shortest cycle and 11 days from the longest cycle. The days between these two numbers are considered fertile, and unprotected intercourse should be avoided during this time.

With perfect use, the calendar method is approximately 95% effective at preventing pregnancy. However, typical use effectiveness is around 77%, due to the natural variation in cycle lengths and the difficulty of accurately predicting ovulation based solely on calendar calculations.

The calendar method offers the advantage of being non-invasive, free, and acceptable to those with religious or personal objections to other contraceptive methods. It can help women understand their menstrual cycles and fertility patterns. However, it is less reliable for women with irregular cycles and does not protect against sexually transmitted infections.

Basal Body Temperature Method

The basal body temperature (BBT) method involves tracking a woman’s resting body temperature throughout the menstrual cycle to identify the fertile window. A woman’s basal body temperature typically drops slightly just before ovulation and then rises by about 0.5-1 degree Fahrenheit after ovulation, remaining elevated until the next period begins.

To use this method, women must take their temperature with a special basal thermometer every morning before getting out of bed or engaging in any activity. The temperature readings are recorded on a chart to identify the pattern of temperature changes. Unprotected intercourse should be avoided from the first day of menstruation until at least 3 days after the temperature rise indicates ovulation has occurred.

With perfect use, the basal body temperature method is approximately 99% effective at preventing pregnancy. However, typical use effectiveness is around 88%, due to factors like illness, stress, alcohol consumption, or inconsistent measurement that can affect temperature readings.

The BBT method offers the advantage of being non-invasive, relatively inexpensive, and acceptable to those with religious or personal objections to other contraceptive methods. It can help women understand their menstrual cycles and confirm that ovulation has occurred. However, it only identifies ovulation after it has happened, making it more useful for planning pregnancy than avoiding it. It does not protect against sexually transmitted infections.

Cervical Mucus Method

The cervical mucus method, also known as the ovulation method or Billings method, involves tracking changes in cervical mucus throughout the menstrual cycle to identify fertile days. As ovulation approaches, cervical mucus typically becomes more abundant, clear, slippery, and stretchy (similar to egg whites), making it easier for sperm to travel through the cervix. After ovulation, the mucus becomes thicker, cloudier, and less abundant.

To use this method, women check their cervical mucus daily by wiping the vaginal opening with toilet paper or clean fingers and noting the color, consistency, and amount. The days when the mucus is clear, slippery, and stretchy are considered fertile, and unprotected intercourse should be avoided during this time.

With perfect use, the cervical mucus method is approximately 97% effective at preventing pregnancy. However, typical use effectiveness is around 88%, due to factors like vaginal infections, semen residue, or inconsistent observation that can affect mucus interpretation.

The cervical mucus method offers the advantage of being non-invasive, free, and acceptable to those with religious or personal objections to other contraceptive methods. It can help women understand their menstrual cycles and identify approaching ovulation. However, it may be difficult for some women to interpret mucus changes, and factors like stress, illness, or medications can affect mucus patterns. It does not protect against sexually transmitted infections.

Symptothermal Method

The symptothermal method combines multiple fertility awareness techniques, typically including basal body temperature tracking, cervical mucus observation, and sometimes additional signs like cervical position, breast tenderness, or ovulation pain. By cross-checking multiple indicators, this method aims to provide a more accurate identification of fertile days than any single method alone.

To use this method, women track their basal body temperature daily, observe cervical mucus changes, and note other fertility signs. The combination of indicators helps identify the beginning and end of the fertile window, allowing couples to avoid unprotected intercourse during this time.

With perfect use, the symptothermal method is approximately 99.6% effective at preventing pregnancy. Typical use effectiveness is around 98%, making it one of the most effective fertility awareness-based methods.

The symptothermal method offers the advantage of being non-invasive, relatively inexpensive, and acceptable to those with religious or personal objections to other contraceptive methods. It provides a comprehensive understanding of menstrual cycles and fertility patterns. However, it requires significant commitment, education, and consistent practice to be effective. It does not protect against sexually transmitted infections.

Standard Days Method

The Standard Days Method is a simplified fertility awareness-based method that works best for women with regular menstrual cycles between 26 and 32 days long. The method identifies days 8 through 19 of the cycle as fertile, and unprotected intercourse should be avoided during this time.

To use this method, women track their menstrual cycles using a special tool called CycleBeads, a color-coded string of beads that helps identify fertile and non-fertile days. Alternatively, they can use a smartphone app or calendar to track their cycles.

With perfect use, the Standard Days Method is approximately 95% effective at preventing pregnancy. However, typical use effectiveness is around 88%, due to the natural variation in cycle lengths and the difficulty of adhering to the method consistently.

The Standard Days Method offers the advantage of being simple to learn and use, non-invasive, and acceptable to those with religious or personal objections to other contraceptive methods. It is particularly suitable for women with regular cycles who prefer a straightforward approach to fertility awareness. However, it is not recommended for women with irregular cycles or cycles shorter than 26 days or longer than 32 days. It does not protect against sexually transmitted infections.

Emergency Contraception

Emergency contraception refers to methods used to prevent pregnancy after unprotected sexual intercourse or contraceptive failure. These methods are not intended for regular use but as a backup option when other contraceptive methods fail or are not used.

Emergency Contraceptive Pills

Emergency contraceptive pills, often called “morning-after pills,” contain hormones that work primarily by delaying or preventing ovulation. They may also work by preventing fertilization or implantation, though these mechanisms are less well-established. There are two main types of emergency contraceptive pills available:

  1. Levonorgestrel pills (e.g., Plan B One-Step, Take Action): These contain a progestin hormone and are available over-the-counter without age restrictions. They are most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, though they may still provide some protection up to 120 hours (5 days) after.
  2. Ulipristal acetate (e.g., ella): This is a selective progesterone receptor modulator that requires a prescription. It is effective up to 120 hours (5 days) after unprotected intercourse and may be more effective than levonorgestrel pills, particularly for women with higher body weights.

Levonorgestrel emergency contraceptive pills are approximately 89% effective when taken within 72 hours of unprotected intercourse, with effectiveness decreasing over time. Ulipristal acetate is approximately 85% effective when taken within 120 hours, with less decrease in effectiveness over time compared to levonorgestrel.

Common side effects of emergency contraceptive pills include nausea, vomiting, abdominal pain, fatigue, headache, dizziness, and irregular bleeding or spotting. These side effects are usually mild and resolve within a few days. If vomiting occurs within 2 hours of taking the medication, a repeat dose may be necessary.

Emergency contraceptive pills offer the advantage of being readily available (particularly levonorgestrel pills) and providing an important backup option for contraceptive emergencies. They do not affect future fertility or increase the risk of birth defects if pregnancy occurs. However, they are less effective than regular contraceptive methods and do not protect against sexually transmitted infections.

Copper IUD as Emergency Contraception

The copper IUD can also be used as emergency contraception when inserted by a healthcare provider within 5 days of unprotected intercourse. It works by creating an inflammatory response in the uterus that is toxic to sperm and prevents implantation.

When used as emergency contraception, the copper IUD is more than 99% effective at preventing pregnancy, making it the most effective emergency contraceptive method available. Additionally, it provides ongoing contraception for up to 10-12 years if left in place.

Potential side effects and risks are similar to those of the copper IUD used for regular contraception, including heavier and more painful periods, increased cramping, and a small risk of infection or uterine perforation during insertion.

The copper IUD offers the advantage of being the most effective emergency contraceptive method while also providing long-term ongoing contraception. It is suitable for women who desire highly effective, long-acting contraception after an emergency situation. However, it requires insertion by a healthcare provider, which may not be immediately accessible to all women. Like other non-barrier methods, it does not protect against sexually transmitted infections.

Lactational Amenorrhea Method (LAM)

The Lactational Amenorrhea Method (LAM) is a temporary contraceptive method based on the natural postpartum infertility that occurs when certain conditions are met. For LAM to be effective, three criteria must be satisfied:

  1. The mother’s menstrual periods have not returned since giving birth.
  2. The mother is exclusively or nearly exclusively breastfeeding.
  3. The baby is less than six months old.

When these three conditions are met, LAM is approximately 98% effective at preventing pregnancy. However, if any of these conditions change, the effectiveness decreases significantly, and another contraceptive method should be used.

LAM works by suppressing ovulation through the hormonal effects of frequent breastfeeding. Prolactin, the hormone responsible for milk production, inhibits the release of gonadotropin-releasing hormone (GnRH), which in turn suppresses ovulation.

LAM offers the advantage of being natural, free, and immediately available postpartum. It supports optimal breastfeeding practices and provides important health benefits for both mother and baby. However, it is only a temporary method, and women must transition to another contraceptive method when any of the three criteria are no longer met. It does not protect against sexually transmitted infections.

Withdrawal Method (Coitus Interruptus)

The withdrawal method, also known as coitus interruptus or “pulling out,” involves the man withdrawing his penis from the vagina before ejaculation to prevent sperm from entering the vagina. This method relies on the man’s ability to recognize when ejaculation is imminent and to withdraw in time.

With perfect use, the withdrawal method is approximately 96% effective at preventing pregnancy. However, typical use effectiveness is around 78%, due to factors like difficulty timing the withdrawal correctly, pre-ejaculate fluid containing sperm, and inconsistent use.

The main challenge with the withdrawal method is that it requires significant self-control and awareness from the male partner. Additionally, pre-ejaculate fluid may contain sperm, particularly if there has been a recent ejaculation, which can lead to pregnancy even if withdrawal is performed correctly.

The withdrawal method offers the advantage of being free, always available, and acceptable to those with religious or personal objections to other contraceptive methods. It does not have any hormonal side effects or require any devices or medications. However, it is less reliable than many other contraceptive methods and does not protect against sexually transmitted infections.

Abstinence

Abstinence is the practice of refraining from sexual intercourse. It is the only contraceptive method that is 100% effective at preventing pregnancy when practiced consistently. Abstinence can be practiced continuously or periodically, such as during fertile days if pregnancy prevention is the goal.

Abstinence offers the advantage of being completely effective at preventing pregnancy and sexually transmitted infections when practiced consistently. It has no side effects, costs nothing, and may be aligned with personal, cultural, or religious values.

However, abstinence requires significant commitment and communication between partners. It may not be a realistic long-term option for everyone, particularly those in committed relationships who desire sexual intimacy. Additionally, if abstinence is discontinued without adopting another contraceptive method, the risk of pregnancy increases.

Choosing the Right Contraceptive Method

Selecting the most appropriate contraceptive method is a personal decision that depends on various factors, including individual health considerations, lifestyle, relationship status, reproductive goals, and personal preferences. Consulting with a healthcare provider can help individuals and couples make informed choices based on their unique circumstances.

Health Considerations

Certain medical conditions may affect the safety and suitability of different contraceptive methods. For example:

  • Women with a history of blood clots, stroke, heart disease, certain types of cancer, or migraine with aura may be advised against using combined hormonal contraceptives due to the increased risk of cardiovascular complications.
  • Women with certain reproductive system abnormalities, active pelvic inflammatory disease, or unexplained vaginal bleeding may not be suitable candidates for IUDs.
  • Women with breast cancer or a history of breast cancer may be advised against using hormonal contraceptives due to the potential effects of hormones on cancer growth.
  • Women with multiple sexual partners or those at high risk of sexually transmitted infections should be encouraged to use barrier methods, particularly condoms, in addition to any other contraceptive method.

A thorough medical history and physical examination can help identify any contraindications to specific contraceptive methods and guide the selection of the safest and most appropriate options.

Lifestyle and Relationship Factors

Lifestyle and relationship factors play a significant role in contraceptive decision-making:

  • Frequency of sexual activity may influence the choice between methods used only at the time of intercourse (like condoms or diaphragms) and those that provide continuous protection (like pills, patches, or IUDs).
  • Stability of the relationship may affect decisions about contraceptive methods that require partner cooperation (like condoms or withdrawal) versus those that are under the woman’s control.
  • Religious or cultural beliefs may influence the acceptability of certain contraceptive methods, particularly those that may work after fertilization (like IUDs or emergency contraception).
  • Personal comfort with different methods, including ease of use, discretion, and impact on sexual spontaneity, can affect adherence and satisfaction with a chosen method.

Open communication between partners and with healthcare providers can help identify lifestyle and relationship factors that may influence contraceptive choices and ensure that the selected method aligns with personal values and preferences.

Reproductive Goals

Future reproductive goals are a crucial consideration in contraceptive decision-making:

  • Individuals or couples who desire children in the near future may prefer methods that allow for a quick return to fertility after discontinuation, such as barrier methods, fertility awareness-based methods, or short-acting hormonal methods.
  • Those who have completed their families or do not desire children may opt for long-acting reversible contraceptive methods like IUDs or implants, or permanent methods like sterilization.
  • Age-related fertility decline may influence the choice of contraceptive method, with older women potentially having different priorities and risk tolerances than younger women.

Regular reassessment of reproductive goals is important, as they may change over time due to various life circumstances. Healthcare providers can help individuals and couples evaluate their reproductive goals and select contraceptive methods that align with their family planning intentions.

Effectiveness and Reliability

The effectiveness and reliability of contraceptive methods vary significantly, and these factors should be weighed against individual needs and preferences:

  • Individuals who absolutely cannot tolerate the risk of pregnancy may prefer the most effective methods, such as sterilization, IUDs, or implants, which have typical use effectiveness rates above 99%.
  • Those who are more comfortable with a small risk of pregnancy may prioritize other factors like convenience, side effects, or non-contraceptive benefits over maximum effectiveness.
  • Personal discipline and consistency in using a method should be realistically assessed, as methods requiring daily action (like pills) or correct use at the time of intercourse (like condoms or diaphragms) may be less effective for individuals who struggle with adherence.

Healthcare providers can provide accurate information about the effectiveness rates of different methods and help individuals and couples evaluate how these rates align with their personal risk tolerance and contraceptive needs.

After Effects and Considerations

All contraceptive methods have potential after effects and considerations that should be carefully weighed when making a decision. Understanding these effects can help individuals and couples make informed choices and manage expectations about their selected method.

Hormonal Contraceptive Side Effects

Hormonal contraceptives can cause a range of side effects, which vary depending on the specific method and individual response:

Common side effects of combined hormonal methods (pills, patch, ring) include:

  • Nausea, particularly during the first few months of use
  • Breast tenderness or enlargement
  • Headaches or migraines
  • Mood changes, including depression or anxiety
  • Weight gain or fluid retention
  • Changes in menstrual bleeding patterns, including breakthrough bleeding or missed periods

Common side effects of progestin-only methods (mini-pills, implants, injections, hormonal IUDs) include:

  • Irregular menstrual bleeding or spotting, particularly during the first few months
  • Amenorrhea (absence of periods), particularly with long-term use of injections or implants
  • Headaches or dizziness
  • Breast tenderness
  • Mood changes
  • Weight gain, particularly with the contraceptive injection

More serious but rare side effects of hormonal contraceptives include:

  • Blood clots, particularly with combined hormonal methods
  • Stroke or heart attack, particularly in women over 35 who smoke
  • Gallbladder disease
  • Liver tumors
  • Increased blood pressure

Most side effects of hormonal contraceptives are mild and resolve within the first few months of use as the body adjusts. However, persistent or severe side effects should be discussed with a healthcare provider, who may recommend switching to a different method or formulation.

Barrier Method Considerations

Barrier methods have their own set of considerations and potential issues:

  • Allergic reactions to materials like latex (in condoms) or spermicides
  • Irritation or discomfort from diaphragms, cervical caps, or sponges
  • Reduced sexual sensation, particularly with condoms
  • Interruption of sexual activity for application
  • Increased risk of urinary tract infections with diaphragms and spermicides
  • Higher failure rates compared to many other methods, particularly with typical use

Many of these considerations can be addressed through proper education, practice with application, and trying different brands or types of barrier methods. For example, non-latex condoms are available for those with latex allergies, and different sizes or shapes of diaphragms may improve comfort and effectiveness.

IUD-Related Issues

Both hormonal and copper IUDs can cause specific issues and considerations:

  • Pain or cramping during and after insertion
  • Irregular bleeding or spotting, particularly during the first few months
  • Heavier and more painful periods with copper IUDs
  • Risk of expulsion, where the IUD is partially or completely pushed out of the uterus
  • Risk of perforation, where the IUD punctures the uterine wall (rare)
  • Increased risk of pelvic inflammatory disease, particularly around the time of insertion

Most IUD-related issues are mild and temporary, though some may require medical attention. Regular check-ups can help ensure the IUD remains in place and functioning correctly. Any concerns about IUD-related issues should be discussed with a healthcare provider.

Sterilization Considerations

Sterilization methods have their own set of considerations and potential issues:

  • Surgical risks associated with the procedures, including infection, bleeding, or reactions to anesthesia
  • Regret about the permanent nature of the decision, particularly among younger individuals
  • Potential for surgical failure, though rare
  • Changes in menstrual patterns or hormonal symptoms after tubal ligation (controversial)
  • Post-vasectomy pain syndrome in a small percentage of men

Sterilization is intended to be permanent, though reversal procedures are sometimes possible. However, reversal is expensive, not always successful, and may not be covered by insurance. Individuals considering sterilization should be counseled about the permanent nature of the decision and the potential for regret.

Fertility Awareness Method Challenges

Fertility awareness-based methods present their own set of challenges and considerations:

  • Requires significant commitment, education, and consistent practice
  • Less effective for women with irregular menstrual cycles
  • Requires periods of abstinence or use of barrier methods during fertile days
  • May be affected by factors like stress, illness, travel, or medications that disrupt fertility signs
  • Does not protect against sexually transmitted infections

Success with fertility awareness-based methods often depends on proper education, consistent practice, and clear communication between partners. Some women may find the daily tracking and observation to be burdensome, while others appreciate the increased awareness of their bodies and menstrual cycles.

Emergency Contraception Considerations

Emergency contraception has specific considerations and potential issues:

  • Side effects like nausea, vomiting, abdominal pain, and irregular bleeding
  • Decreased effectiveness over time, particularly for levonorgestrel pills
  • Potential interactions with certain medications that may reduce effectiveness
  • Limited availability or accessibility in some areas
  • Cost considerations, particularly for ulipristal acetate or copper IUD emergency contraception

Emergency contraception is intended for occasional use and should not be relied upon as a regular contraceptive method. Individuals who frequently need emergency contraception may benefit from discussing more effective regular contraceptive options with a healthcare provider.

Contraception and Special Populations

Certain populations may have unique contraceptive needs and considerations that require specialized approaches and counseling.

Adolescents

Adolescents have specific contraceptive needs and considerations:

  • Higher rates of contraceptive failure due to inconsistent use and incorrect use
  • Unique privacy and confidentiality concerns
  • Potential impact of hormonal methods on adolescent growth and development
  • Importance of dual protection against both pregnancy and sexually transmitted infections
  • Need for age-appropriate education and counseling

Long-acting reversible contraceptive methods like IUDs and implants are increasingly recommended for adolescents due to their high effectiveness and low user error. However, individual preferences and circumstances should be considered, and a range of options should be discussed.

Perimenopausal Women

Women approaching menopause have unique contraceptive considerations:

  • Decreasing fertility but continued risk of pregnancy until menopause is confirmed
  • Increased risk of certain health conditions that may affect contraceptive safety
  • Potential benefits of hormonal methods for managing perimenopausal symptoms
  • Need for continued contraception until menopause is confirmed (12 months without periods for women over 50)

Low-dose hormonal contraceptives, progestin-only methods, and non-hormonal options like copper IUDs may be appropriate for perimenopausal women, depending on their health status and symptom management needs.

Women with Chronic Medical Conditions

Women with chronic medical conditions require specialized contraceptive counseling:

  • Certain conditions may contraindicate specific contraceptive methods
  • Some conditions may be affected by hormonal contraceptives
  • Potential interactions between contraceptive methods and medications used to treat chronic conditions
  • Importance of highly effective contraception for women with conditions that make pregnancy risky

Healthcare providers should carefully evaluate the risks and benefits of different contraceptive methods for women with chronic medical conditions, considering both the impact of the method on the condition and the impact of the condition on the method’s effectiveness and safety.

Postpartum Women

Women in the postpartum period have specific contraceptive needs and considerations:

  • Timing of contraception initiation after childbirth
  • Impact of contraceptive methods on breastfeeding
  • Spacing of pregnancies for optimal maternal and infant health
  • Unique contraceptive needs after cesarean section or pregnancy complications

Most contraceptive methods can be safely initiated in the postpartum period, though timing recommendations vary by method and whether the woman is breastfeeding. Non-hormonal methods and progestin-only methods are generally preferred for breastfeeding women, though combined hormonal methods can be considered after the first month postpartum in women who are not breastfeeding.

FAQs

1. What is the most effective contraceptive method?

The most effective contraceptive methods are sterilization (tubal ligation for women and vasectomy for men), intrauterine devices (both hormonal and copper), and contraceptive implants. These methods have typical use effectiveness rates above 99%, meaning fewer than 1 out of 100 users will become pregnant in a year of typical use.

2. Can I get pregnant while using contraception?

Yes, no contraceptive method is 100% effective except for abstinence. The likelihood of pregnancy depends on the method used and how consistently and correctly it is used. Methods with higher typical use effectiveness rates, like IUDs and implants, have very low pregnancy rates, while methods with lower typical use effectiveness rates, like withdrawal or fertility awareness-based methods, have higher pregnancy rates.

3. Do hormonal contraceptives cause weight gain?

Weight gain is a commonly reported side effect of hormonal contraceptives, though research on this topic has produced mixed results. Some studies suggest that certain hormonal methods, particularly the contraceptive injection, may be associated with weight gain, while others find no significant difference in weight between users and non-users of hormonal contraceptives. Individual responses vary, and any concerns about weight changes should be discussed with a healthcare provider.

4. Can I use emergency contraception multiple times?

Yes, emergency contraception can be used multiple times if needed, though it should not be relied upon as a regular contraceptive method. There are no known health risks associated with using emergency contraception multiple times, though it may cause irregular bleeding or other side effects. Women who frequently need emergency contraception should consider discussing more effective regular contraceptive options with a healthcare provider.

5. How soon after stopping contraception can I get pregnant?

The time it takes to become pregnant after stopping contraception varies by method:

  • Barrier methods: Fertility returns immediately after discontinuation.
  • Combined hormonal methods (pills, patch, ring): Fertility typically returns within 1-3 months after stopping.
  • Progestin-only methods: Fertility may return immediately or take a few months, depending on the specific method.
  • IUDs: Fertility typically returns immediately after removal.
  • Contraceptive injection: Fertility may take 6-18 months to return after the last injection.
  • Implant: Fertility typically returns quickly after removal.

6. Do contraceptives protect against sexually transmitted infections?

Only barrier methods, particularly condoms, provide significant protection against most sexually transmitted infections. Other contraceptive methods, while effective at preventing pregnancy, offer little to no protection against STIs. For individuals at risk of STIs, dual protection (using condoms in addition to another contraceptive method) is recommended.

7. Can I use contraception while breastfeeding?

Many contraceptive methods are safe to use while breastfeeding. Non-hormonal methods like copper IUDs, barrier methods, and fertility awareness-based methods do not affect breastfeeding. Progestin-only methods like mini-pills, implants, injections, and hormonal IUDs are also considered safe for breastfeeding mothers and can be started immediately after childbirth. Combined hormonal methods (containing estrogen) are generally not recommended for breastfeeding mothers in the first few weeks postpartum, as they may reduce milk supply.

8. Are there any natural or herbal contraceptives that work?

While various herbs and natural substances have been traditionally used for contraception, there is limited scientific evidence supporting their effectiveness. Some herbs like wild yam, neem, and pennyroyal have been studied for contraceptive effects, but none have been proven to be reliably effective. Natural methods like fertility awareness-based methods can be effective when used correctly and consistently, but they require significant education and commitment.

9. Can contraception affect my sex drive?

The effects of contraception on sex drive (libido) vary among individuals and depend on the specific method. Some people report increased libido due to reduced anxiety about pregnancy, while others report decreased libido, particularly with hormonal methods. Hormonal contraceptives can affect testosterone levels, which may influence sex drive in some individuals. Any concerns about changes in libido should be discussed with a healthcare provider.

10. Is it safe to use contraception for a long time?

For most healthy individuals, using contraception for an extended period is safe. Many hormonal methods have been studied for long-term use and have been found to be safe for most users. However, certain methods may have specific considerations for long-term use. For example, long-term use of the contraceptive injection has been associated with decreased bone density, though this is typically reversible after discontinuation. Regular check-ups with a healthcare provider can help ensure the continued safety of long-term contraceptive use.

11. Can contraception affect my future fertility?

Most contraceptive methods do not have a long-term impact on fertility after discontinuation. Fertility typically returns relatively quickly after stopping most methods, though the timing varies by method (see question 5). Sterilization methods are intended to be permanent, though reversal procedures are sometimes possible. There is no conclusive evidence that long-term use of hormonal contraceptives causes permanent infertility, though it may take some time for fertility to return after stopping certain methods.

12. Are there any age restrictions on contraceptive use?

Most contraceptive methods do not have strict age restrictions, though certain considerations may apply to different age groups. For example, combined hormonal contraceptives are generally not recommended for women over 35 who smoke due to increased cardiovascular risks. Adolescents may have specific counseling needs but can safely use most contraceptive methods. Healthcare providers consider individual health factors rather than age alone when determining contraceptive suitability.

13. Can I use multiple contraceptive methods at the same time?

Yes, using multiple contraceptive methods simultaneously can increase effectiveness and provide additional benefits. For example, using condoms along with another contraceptive method (dual protection) provides both pregnancy prevention and protection against sexually transmitted infections. However, using multiple hormonal methods simultaneously is not recommended and may increase the risk of side effects without providing additional contraceptive benefit.

14. Do contraceptives have any non-contraceptive benefits?

Yes, many contraceptive methods offer non-contraceptive benefits:

  • Combined hormonal contraceptives can reduce menstrual bleeding, relieve menstrual cramps, improve acne, reduce the risk of ovarian and endometrial cancers, and help manage conditions like polycystic ovary syndrome (PCOS) and endometriosis.
  • Progestin-only methods can reduce menstrual bleeding and cramps, and may help manage conditions like endometriosis and uterine fibroids.
  • Hormonal IUDs can significantly reduce or eliminate menstrual bleeding and help manage conditions like endometriosis and heavy menstrual bleeding.
  • Copper IUDs do not have hormonal side effects and can be used by women who cannot or prefer not to use hormonal methods.

15. Can contraception cause infertility?

There is no conclusive evidence that properly used contraceptive methods cause permanent infertility. While some methods may temporarily delay the return of fertility after discontinuation (see question 5), most individuals regain their previous fertility levels within a relatively short time. Sterilization methods are intended to be permanent, though reversal procedures are sometimes possible. Any concerns about fertility after contraceptive use should be discussed with a healthcare provider.

16. Are there any contraceptives that can be used by men besides condoms and vasectomy?

Currently, condoms and vasectomy are the only contraceptive methods available for men. Research is ongoing on male contraceptive options, including hormonal methods, non-hormonal methods, and reversible vasectomy techniques, but none have been approved for widespread use yet. This means that most contraceptive responsibility currently falls on women, highlighting the importance of shared decision-making and communication between partners.

17. Can I use contraception if I have a chronic medical condition?

Many contraceptive methods can be safely used by individuals with chronic medical conditions, though certain methods may be contraindicated for specific conditions. For example:

  • Women with a history of blood clots, stroke, or heart disease may be advised against combined hormonal contraceptives.
  • Women with certain types of migraines may need to avoid estrogen-containing contraceptives.
  • Women with liver disease may have limitations on hormonal contraceptive use.
  • Women with breast cancer or a history of breast cancer may be advised against hormonal contraceptives.

Healthcare providers can help evaluate the risks and benefits of different contraceptive methods based on individual health conditions.

18. Do contraceptives affect the menstrual cycle?

Yes, many contraceptives affect the menstrual cycle:

  • Combined hormonal contraceptives typically make periods more regular, lighter, and less painful. Some formulations can reduce the frequency of periods or eliminate them altogether.
  • Progestin-only methods can cause irregular bleeding patterns, particularly during the first few months of use. Some users may experience amenorrhea (absence of periods) with long-term use.
  • Hormonal IUDs often reduce menstrual bleeding and cramps, and many users experience amenorrhea over time.
  • Copper IUDs may cause heavier and more painful periods, particularly during the first few months of use.
  • Barrier methods and fertility awareness-based methods do not typically affect menstrual cycles.

19. Can I get pregnant during my period?

While the likelihood of pregnancy during menstruation is lower than at other times in the menstrual cycle, it is still possible, particularly for women with shorter or irregular cycles. Sperm can survive in the reproductive tract for up to 5 days, and ovulation can occur earlier than expected in some cycles. If pregnancy is not desired, contraception should be used throughout the entire menstrual cycle.

20. Are there any over-the-counter contraceptive options?

Yes, several contraceptive options are available over-the-counter without a prescription:

  • Male and female condoms
  • Spermicides
  • Contraceptive sponges
  • Emergency contraceptive pills containing levonorgestrel (e.g., Plan B One-Step, Take Action)

Other methods like birth control pills, patches, rings, IUDs, implants, and injections require a prescription and, in some cases, a medical procedure for insertion.

21. Can contraception cause birth defects if I get pregnant while using it?

There is no conclusive evidence that using contraception during early pregnancy causes birth defects. Hormonal contraceptives have been extensively studied, and research has not found an increased risk of birth defects among women who became pregnant while using these methods or who accidentally used them during early pregnancy. However, if pregnancy is suspected while using contraception, it is important to discontinue the method and consult with a healthcare provider.

22. How do I know which contraceptive method is right for me?

Choosing the right contraceptive method is a personal decision that depends on various factors, including:

  • Your overall health and any medical conditions
  • Your menstrual cycle and any related symptoms
  • Your sexual activity and STI risk
  • Your future reproductive goals
  • Your personal preferences and comfort with different methods
  • Your ability to use methods consistently and correctly

Consulting with a healthcare provider can help you evaluate these factors and select the method that best meets your needs.

23. Can contraception help with medical conditions like PCOS or endometriosis?

Yes, certain contraceptive methods can help manage symptoms of medical conditions like polycystic ovary syndrome (PCOS) and endometriosis:

  • Combined hormonal contraceptives can help regulate menstrual cycles, reduce androgen levels, and improve acne in women with PCOS.
  • Both combined hormonal contraceptives and progestin-only methods can help reduce the growth of endometrial tissue and alleviate pain associated with endometriosis.
  • Hormonal IUDs can reduce menstrual bleeding and pain associated with endometriosis and adenomyosis.

Healthcare providers can recommend specific contraceptive methods based on individual health conditions and symptoms.

24. Are there any contraceptives that can be used continuously without breaks?

Yes, several contraceptive methods can be used continuously without breaks:

  • Combined hormonal contraceptives (pills, patch, ring) can be used continuously by skipping the placebo week or ring-free interval. Some formulations are specifically designed for continuous use.
  • Progestin-only pills can be taken continuously without breaks.
  • Hormonal IUDs and implants provide continuous contraception without the need for breaks.
  • Contraceptive injections provide continuous protection for 3 months at a time.

Continuous use can eliminate withdrawal bleeding for many users, though some may experience irregular spotting or bleeding, particularly during the first few months.

25. Can contraception affect my mood or mental health?

Some individuals report mood changes or mental health effects while using hormonal contraceptives, including depression, anxiety, or mood swings. Research on this topic has produced mixed results, with some studies suggesting a potential link between hormonal contraceptives and mood changes, while others find no significant association. Individual responses vary, and anyone experiencing significant mood changes while using contraception should discuss them with a healthcare provider, who may recommend switching to a different method.

26. Are there any non-hormonal contraceptive options besides barrier methods?

Yes, there are several non-hormonal contraceptive options besides barrier methods:

  • Copper IUD: A long-acting, highly effective method that does not contain hormones.
  • Fertility awareness-based methods: Natural methods that involve tracking menstrual cycles and avoiding intercourse during fertile days.
  • Sterilization: Permanent surgical methods for both women (tubal ligation) and men (vasectomy).
  • Withdrawal method: Involves withdrawing the penis before ejaculation, though this method has a relatively high failure rate.

These options can be suitable for individuals who cannot or prefer not to use hormonal methods.

27. Can I use contraception if I’m trying to regulate my menstrual cycle?

Yes, certain contraceptive methods can help regulate menstrual cycles:

  • Combined hormonal contraceptives (pills, patch, ring) typically make periods more regular and predictable.
  • Progestin-only methods may also help regulate cycles, though they can sometimes cause irregular bleeding, particularly during the first few months of use.
  • Hormonal IUDs often reduce or eliminate menstrual bleeding over time.

Healthcare providers can recommend specific methods based on individual menstrual cycle concerns and overall health.

28. Are there any contraceptives that can be used discreetly without a partner knowing?

Yes, several contraceptive methods can be used discreetly without a partner’s knowledge:

  • Birth control pills can be taken privately without a partner’s awareness.
  • The contraceptive patch can be placed in discreet locations on the body.
  • The vaginal ring is inserted into the vagina and is not typically felt by a partner during intercourse.
  • Hormonal IUDs and implants are inserted by healthcare providers and provide long-term contraception without requiring daily attention or partner involvement.
  • Contraceptive injections are administered by healthcare providers every 3 months and do not require partner involvement.

The choice of a discreet method depends on individual preferences, health considerations, and the need for STI protection.

29. Can contraception affect my risk of certain cancers?

Yes, contraceptive use can affect the risk of certain cancers:

  • Combined hormonal contraceptives have been shown to reduce the risk of ovarian and endometrial cancers. This protective effect increases with longer duration of use and persists for many years after discontinuation.
  • Some studies suggest a small increased risk of breast cancer associated with current or recent use of combined hormonal contraceptives, though this risk appears to return to normal within a few years after discontinuation.
  • Some studies suggest a small increased risk of cervical cancer associated with long-term use of combined hormonal contraceptives, though this risk may be related to other factors like sexual behavior and HPV infection.
  • Copper IUDs do not appear to affect cancer risk.

Individual cancer risk factors should be discussed with a healthcare provider when selecting a contraceptive method.

30. How often should I discuss my contraceptive method with my healthcare provider?

It’s generally recommended to discuss your contraceptive method with your healthcare provider at least annually during routine check-ups. However, you should schedule an earlier discussion if you experience:

  • Significant side effects or changes in your health
  • Changes in your menstrual cycle or bleeding patterns
  • Changes in your relationship status or sexual activity
  • Changes in your reproductive goals
  • Difficulty using your method consistently and correctly

Regular check-ins with your healthcare provider can ensure that your chosen method continues to meet your needs and that any concerns or issues are addressed promptly.
