1. Combined oral contraceptives (COCs): These contain both estrogen and progestin hormones. They work by preventing ovulation, thickening cervical mucus to prevent sperm from reaching the egg, and thinning the uterine lining to prevent implantation.
2. Progestin-only contraceptives: These include progestin-only pills, injections, implants, and intrauterine devices (IUDs). They primarily work by thickening cervical mucus and thinning the uterine lining to prevent sperm from reaching the egg and implantation.
3. Emergency contraception: This includes the "morning-after pill" which contains high doses of progestin or a combination of estrogen and progestin. It works by preventing or delaying ovulation, inhibiting fertilization, or preventing implantation.
4. Hormonal contraceptives for men: These are still in development but may include testosterone-based injections or implants to suppress sperm production.
5. Hormonal contraceptives for women with specific health conditions: These may include low-dose estrogen pills for women at risk of blood clots, progestin-only methods for women who cannot take estrogen, or hormonal IUDs for women with heavy menstrual bleeding.
Overall, hormonal contraceptives work by altering hormone levels in the body to prevent pregnancy through various mechanisms such as inhibiting ovulation, thickening cervical mucus, and thinning the uterine lining.
