What 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:
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” (how people usually use it or if it’s not used every time you have sex) vs. “perfect use” (when it’s used perfectly, every time you have sex). Keep in mind that perfect use hardly ever happens.
