What Is Ortho Evra Birth Control Patch?
Ortho evra patch is used as a birth control method in which a thin, plastic patch is stick on the skin of the women to prevent pregnancy. After every seven days, the old patch must be replaced with the new one and this must be continued for three consecutive weeks and the fourth week in a month must be kept patch free.
Just like other birth control pills, ortho evra patch releases hormones in the blood stream through the skin. Hormones play an important role in controlling functions of various parts of the body. Estrogen and progesterone are the two types of hormones found in ortho evra patch.
The hormones present in the ortho evra patch prevent the ovaries from releasing eggs due to which ovulation will not occur. If there is no egg available for the sperm to fertilize, it is not possible for women to get pregnant. Patch hormones cause thickening of the cervical mucus thereby preventing pregnancy. Due to the thickened mucus, the sperms will be blocked and will not be able to reach egg to fertilize it. The linings of the uterus are also made thin by the hormone present in the ortho evra patch due to which the egg will not be able to attach to the uterus.
