Human-made oestrogen and progestin hormones are present in all hormonal contraceptives (the pill, the patch, and the vaginal ring). These hormones work by interfering with your body's natural hormones in a variety of ways to prevent conception. In most cases, the hormonal contraceptive prevents the body from ovulating. Birth control is a method of avoiding pregnancy. There are a variety of birth control options available, including hormonal contraception such as "the pill." The combined oral contraceptive pill is commonly referred to simply as "the pill." It includes synthetic copies of the female hormone’s oestrogen and progesterone, which are naturally produced in the ovaries. Some people take the pill by mouth to prevent pregnancy, and it is up to 99.9% effective when taken appropriately. The pill, on the other hand, does not protect you from sexually transmitted infections such as HIV. Most STDs are best protected by using a latex condom to cover a penis. The patch and the vaginal ring are two more types of combined oestrogen and progestin hormonal contraception.
