birth control patch definition
The birth control patch is a method of hormonal contraception. Ortho Evra, the birth control patch, was introduced in 2002. The patch is a highly effective birth control with approximately six of 100 women becoming pregnant in a year of typical use. A birth control patch is a small square patch that looks like a band-aid. It sticks to the skin and gradually releases hormones into the body to prevent pregnancy. It is replaced once a week.
