hormonal methodsWhat are hormonal methods of birth control?

Hormonal methods of birth control are types of birth control that use hormones (estrogen and/or progestin) to help prevent ovulation. There are many different types of hormonal birth control, and they vary in their effectiveness.

What are the different types of female hormonal methods?

There are six types of female hormonal methods:

  1. Birth Control Pills
  2. Depo-Provera® Hormonal Injections
  3. Estrogen/Progestin Hormonal Injections
  4. Hormonal Implants
  5. Hormone Patch (Ortho-Evra®)
  6. Vaginal Hormonal Ring (NuvaRing®)

How does each method work, and how effective are they at preventing pregnancy?

Each female hormonal method has a different efficacy rate towards preventing pregnancy. These rates vary depending on “typical use” vs. “perfect use”. Keep in mind that perfect use hardly ever happens.

Birth Control Pills

Birth control pills (also called oral contraceptive pills or the “Pill”) are small tablets that a woman takes each day. The pills are made up of hormones (progestin-only or a combination of estrogen and progestin) that work to prevent pregnancy.
