Hormonal methods of birth control are contraceptive methods that use hormones to prevent pregnancy. These methods work by altering a woman's hormonal balance to prevent ovulation, thicken cervical mucus to block sperm, or thin the lining of the uterus to prevent implantation of a fertilized egg. Some common hormonal methods of birth control include:
1. Combination birth control pills: These pills contain both estrogen and progestin hormones and are taken daily to prevent ovulation.
2. Progestin-only pills (mini-pills): These pills contain only progestin hormone and are taken daily to prevent ovulation and thicken cervical mucus.
3. Birth control patch: This is a small patch that is applied to the skin and releases estrogen and progestin hormones to prevent ovulation.
4. Birth control shot (Depo-Provera): This is an injection of progestin hormone that is given every three months to prevent ovulation.
5. Birth control implant (Nexplanon): This is a small rod that is inserted under the skin of the upper arm and releases progestin hormone to prevent ovulation for up to three years.
6. Hormonal intrauterine device (IUD): This is a T-shaped device that is inserted into the uterus and releases progestin hormone to prevent ovulation for up to five years.
It is important to note that hormonal methods of birth control do not protect against sexually transmitted infections (STIs).
