Birth Control Hormones: The Ring

Table of Contents


Topic Overview

What is the ring?

The ring is used to prevent pregnancy. It's a soft plastic ring that you put into your vagina. It's also called the vaginal ring.

The ring releases a regular dose of the hormones estrogen and progestin. These hormones prevent pregnancy in three ways. They thicken the mucus in the cervix. This makes it hard for sperm to travel into the uterus. They thin the lining of the uterus, which makes it harder for a fertilized egg to attach to the uterus. The hormones also can stop the ovaries from releasing an egg each month (ovulation).

The ring protects against pregnancy for 1 month at a time. You wear one ring for 3 weeks in a row and then go without a ring for 1 week. During the week without the ring, you have your period. Your period may be very light.
