Hormonal methods refer to contraceptive methods that use hormones to prevent pregnancy. These methods work by altering a woman's natural hormonal balance to prevent ovulation, thicken cervical mucus to block sperm from reaching the egg, or thin the lining of the uterus to prevent implantation of a fertilized egg. Some common hormonal methods include:
1. Birth control pills: These are oral contraceptives that contain synthetic hormones (estrogen and progestin) to prevent ovulation.
2. Birth control patch: It is a small adhesive patch that releases hormones through the skin to prevent pregnancy.
3. Birth control shot: Also known as Depo-Provera, it is an injection of progestin that provides contraception for three months.
4. Birth control implant: It is a small rod inserted under the skin of the upper arm that releases progestin to prevent pregnancy for up to three years.
5. Hormonal intrauterine device (IUD): Some IUDs release progestin to prevent pregnancy for several years.
6. Vaginal ring: It is a flexible ring that is inserted into the vagina and releases hormones to prevent pregnancy.
It is important to note that hormonal methods do not protect against sexually transmitted infections (STIs), so additional protection like condoms may be necessary for STI prevention.
