II. Hormonal Methods

A. Combined Oral Contraceptive Pill

1. How it works The combined oral contraceptive pill contains both estrogen and progestin hormones. It works by inhibiting ovulation, thickening cervical mucus to prevent sperm from reaching the egg, and thinning the uterine lining to reduce the likelihood of implantation.
2. Effectiveness With perfect use, the combined pill is about 99% effective. However, with typical use, the effectiveness drops to about 91% due to missed pills or other inconsistencies in taking the pill.
3. Benefits and side effects Benefits of the combined pill include reduced menstrual cramps, lighter and more regular periods, and improved acne. Side effects may include nausea, breast tenderness, headaches, and a slightly increased risk of blood clots.

B. Progestin-only Pill

1. How it works The progestin-only pill, also known as the “mini-pill,” contains only progestin. It primarily works by thickening the cervical mucus and thinning the uterine lining. In some cases, it may also suppress ovulation.
2. Effectiveness The progestin-only pill has an effectiveness rate of about 91% with typical use.
3. Benefits and side effects Benefits include suitability for breastfeeding mothers and those who cannot take estrogen for medical reasons. Side effects may include irregular bleeding, weight gain, and breast tenderness.

C. Contraceptive Patch

1. How it works The contraceptive patch is a transdermal patch that releases estrogen and progestin into the bloodstream. It works similarly to the combined pill, preventing ovulation, thickening cervical mucus, and thinning the uterine lining.
2. Effectiveness The contraceptive patch is about 91% effective with typical use.
3. Benefits and side effects Benefits include ease of use and not having to remember a daily pill. Side effects may include skin irritation, breast tenderness, and a slightly increased risk of blood clots.

D. Vaginal Ring

1. How it works The vaginal ring is a small, flexible ring inserted into the vagina that releases estrogen and progestin. It works in the same way as the combined pill and contraceptive patch.
2. Effectiveness With typical use, the vaginal ring is about 91% effective.
3. Benefits and side effects Benefits include ease of use and a lower daily hormone dose compared to the combined pill. Side effects may include vaginal discharge, irritation, and a slightly increased risk of blood clots.

E. Injectable Contraceptives

1. How it works Injectable contraceptives, such as Depo-Provera, are progestin-only injections administered every three months. They work by inhibiting ovulation, thickening cervical mucus, and thinning the uterine lining.
2. Effectiveness Injectable contraceptives are about 94% effective with typical use.
3. Benefits and side effects Benefits include convenience and discretion. Side effects may include irregular bleeding, weight gain, and a potential delay in the return of fertility after stopping the injections.

F. Hormonal Intrauterine Devices (IUDs)

1. How it works Hormonal IUDs, such as Mirena and Skyla, release progestin directly into the uterus. They work by thickening cervical mucus, thinning the uterine lining, and, in some cases, inhibiting ovulation.
2. Effectiveness Hormonal IUDs are over 99% effective.
3. Benefits and side effects Benefits include long-term protection (3-7 years), reduced menstrual bleeding, and the ability to use while breastfeeding. Side effects may include irregular bleeding, ovarian cysts, and hormonal side effects such as headaches, acne, and mood changes.

G. Implants

1. How it works The contraceptive implant, such as Nexplanon, is a small, flexible rod inserted under the skin of the upper arm. It releases progestin, which inhibits ovulation, thickens cervical mucus, and thins the uterine lining.
2. Effectiveness The contraceptive implant is over 99% effective.
3. Benefits and side effects Benefits include long-term protection (up to 3 years), convenience, and discretion. Side effects may include irregular bleeding, weight gain, and hormonal side effects such as mood changes and acne.

III. Barrier Methods

A. Male Condoms

1. How it works Male condoms are thin sheaths made of latex, polyurethane, or lambskin that cover the penis during intercourse. They work by creating a physical barrier that prevents sperm from entering the vagina and reaching the egg.
2. Effectiveness With typical use, male condoms are about 85% effective. With perfect use, their effectiveness increases to 98%.
3. Benefits and side effects Benefits include ease of use, affordability, and protection against sexually transmitted infections (STIs). Side effects are rare but may include allergic reactions to latex or irritation from lubricants or spermicides.

B. Female Condoms

1. How it works Female condoms are thin pouches made of nitrile or polyurethane that are inserted into the vagina before intercourse. Like male condoms, they create a physical barrier that prevents sperm from reaching the egg.
2. Effectiveness Female condoms are about 79% effective with typical use and 95% effective with perfect use.
3. Benefits and side effects Benefits include protection against STIs, ease of use, and compatibility with oil-based lubricants. Side effects may include discomfort during insertion or intercourse and a higher risk of slipping compared to male condoms.

C. Diaphragm

1. How it works The diaphragm is a shallow, dome-shaped cup made of silicone that is inserted into the vagina before intercourse. It works by covering the cervix, preventing sperm from entering the uterus. Diaphragms are typically used with spermicide for increased effectiveness.
2. Effectiveness With typical use, the diaphragm is about 88% effective. With perfect use, its effectiveness increases to 94%.
3. Benefits and side effects Benefits include being non-hormonal, reusable, and providing some protection against pelvic inflammatory disease. Side effects may include an increased risk of urinary tract infections and allergic reactions to the spermicide or diaphragm material.

D. Cervical Cap

1. How it works The cervical cap is a small, thimble-shaped silicone cup that is inserted into the vagina to cover the cervix before intercourse. Like the diaphragm, it is typically used with spermicide to increase effectiveness.
2. Effectiveness For women who have never given birth, the cervical cap is about 86% effective with typical use and 91% effective with perfect use. For women who have given birth, its effectiveness drops to 71% with typical use and 74% with perfect use.
3. Benefits and side effects Benefits include being non-hormonal, reusable, and providing some protection against pelvic inflammatory disease. Side effects may include an increased risk of urinary tract infections, allergic reactions to the spermicide or cap material, and discomfort during insertion or intercourse.

IV. Intrauterine Devices (Non-hormonal)

A. Copper IUD

1. How it works The copper IUD, such as ParaGard, is a small T-shaped device made of plastic and wrapped with copper wire. It is inserted into the uterus by a healthcare provider. The copper IUD works by releasing copper ions, which are toxic to sperm, impairing their ability to swim and fertilize an egg. Additionally, the presence of the device in the uterus creates an inflammatory response, making the environment inhospitable for sperm and a fertilized egg.
2. Effectiveness The copper IUD is over 99% effective.
3. Benefits and side effects Benefits include long-term protection (up to 10 years), being hormone-free, and the ability to use it as emergency contraception. Side effects may include heavier and more painful periods, cramping, and an increased risk of expulsion or perforation (rare).

B. Non-hormonal IUD Alternatives While the copper IUD is the most common non-hormonal IUD option, there are other non-hormonal alternatives for those who cannot use or prefer not to use hormonal methods. These alternatives may include barrier methods such as condoms, diaphragms, and cervical caps, as well as fertility awareness-based methods.

V. Emergency Contraception

A. Morning-After Pill

1. How it works The morning-after pill, also known as emergency contraception, consists of either levonorgestrel (Plan B One-Step) or ulipristal acetate (ella). Levonorgestrel works by delaying or inhibiting ovulation, preventing fertilization. Ulipristal acetate works by delaying ovulation and may also interfere with the implantation of a fertilized egg.
2. Effectiveness Levonorgestrel is most effective when taken within 72 hours of unprotected intercourse, with an effectiveness rate of about 89%. Ulipristal acetate is effective up to 120 hours after unprotected intercourse, with an effectiveness rate of about 85%. The effectiveness of both types of morning-after pills decreases as more time passes after unprotected intercourse.
3. Benefits and side effects Benefits include being available without a prescription (levonorgestrel) and the ability to use them as a backup method if regular contraception fails or is not used. Side effects may include nausea, vomiting, abdominal pain, fatigue, and changes in menstrual bleeding.

B. Copper IUD as Emergency Contraception

1. How it works A copper IUD can be used as emergency contraception if inserted within five days of unprotected intercourse. It works by creating a toxic environment for sperm, preventing fertilization, and by creating an inflammatory response that makes the uterus inhospitable for a fertilized egg.
2. Effectiveness The copper IUD is over 99% effective when used as emergency contraception.
3. Benefits and side effects Benefits include providing long-term contraception (up to 10 years) after insertion and being hormone-free. Side effects may include heavier and more painful periods, cramping, and a rare risk of expulsion or perforation.

VI. Natural Methods

A. Fertility Awareness-Based Methods

1. How it works Fertility awareness-based methods (FABMs) involve tracking a woman’s menstrual cycle and identifying the fertile window to either avoid or achieve pregnancy. There are various techniques, including tracking basal body temperature, cervical mucus changes, and calendar-based methods like the Standard Days Method or the Symptothermal Method, which combines multiple tracking methods.
2. Effectiveness The effectiveness of FABMs varies depending on the specific method used and the individual’s adherence to the method. With typical use, the effectiveness ranges from 76% to 88%. With perfect use, the effectiveness can be as high as 95% to 99%.
3. Benefits and side effects Benefits include being hormone-free, low-cost, and promoting a better understanding of one’s menstrual cycle. There are no physical side effects, but the method may be less effective for those with irregular cycles, and it requires diligence and commitment.

B. Withdrawal Method

1. How it works The withdrawal method, or “pulling out,” involves the male partner withdrawing his penis from the vagina before ejaculation to prevent sperm from entering the vagina.
2. Effectiveness With typical use, the withdrawal method is about 78% effective. With perfect use, its effectiveness increases to 96%.
3. Benefits and side effects Benefits include being hormone-free and not requiring any devices or prescriptions. There are no physical side effects, but the method relies heavily on the male partner’s self-control and ability to withdraw in time, making it less reliable than other methods.

C. Lactational Amenorrhea Method

1. How it works The lactational amenorrhea method (LAM) is a temporary form of birth control for breastfeeding mothers. It works by relying on the natural suppression of ovulation due to the hormone prolactin, which is released during breastfeeding. For LAM to be effective, the mother must be exclusively breastfeeding on demand (at least every 4 hours during the day and every 6 hours at night), have not had her period return since giving birth, and her baby must be less than 6 months old.
2. Effectiveness With proper adherence to the LAM criteria, this method is about 98% effective.
3. Benefits and side effects Benefits include being hormone-free, convenient, and promoting breastfeeding. There are no physical side effects, but the method is only suitable for a limited time postpartum and may not be as effective for mothers who supplement breastfeeding with formula.

VII. Permanent Birth Control Methods

A. Tubal Ligation

1. How it works Tubal ligation, commonly known as “having your tubes tied,” is a permanent birth control method for women. It involves surgically closing or blocking the fallopian tubes, which prevents the egg from traveling to the uterus and the sperm from reaching the egg. There are various techniques, including cutting, sealing, or clamping the tubes.
2. Effectiveness Tubal ligation is over 99% effective at preventing pregnancy.
3. Benefits and side effects Benefits include providing a permanent form of contraception and not requiring any ongoing maintenance. Side effects and risks may include complications from surgery (infection, bleeding, or damage to nearby organs), ectopic pregnancy, and regret or desire for reversal, which is not always possible or successful.

B. Vasectomy

1. How it works Vasectomy is a permanent birth control method for men. It involves surgically cutting, sealing, or clamping the vas deferens, which are the tubes that carry sperm from the testicles to the urethra. This prevents sperm from being released during ejaculation.
2. Effectiveness Vasectomy is over 99% effective at preventing pregnancy.
3. Benefits and side effects Benefits include providing a permanent form of contraception, being a less invasive procedure than tubal ligation, and not affecting sexual function. Side effects and risks may include complications from surgery (infection, bleeding, or sperm granuloma), chronic pain in the scrotum (rare), and regret or desire for reversal, which is not always possible or successful.
