The Patch

How it Works

The combination of the hormones progesterone and estrogen in the patch prevents ovulation. If an egg isn't released, a woman can't get pregnant because there's nothing for the male's sperm to fertilize. The hormones in the patch can also sometimes affect the lining of the uterus so that if the egg is fertilized it will have a hard time attaching to the wall of the uterus.

Where is it located ?

The patch can be places in many places such as the abdomen, buttocks, upper arm, or upper torso

Duration of use

A patch should be put on the first day of her menstrual cycle or the first Sunday after her menstrual cycle begins. She will change the patch on her skin once a week for 3 weeks in a row, the fourth week she doesn't wear them, and then repeat.

The stages of fertilization the patch stops

It stops fertilization by increasing mucus in the cervix changing the uterus lining and stopping ovulation from starting.
