Femodene prevents pregnancy mainly by stopping the release of an egg from the ovaries each month (ovulation). It also thickens the cervical mucus, making it more difficult for sperm to enter the womb, and alters the lining of the uterus to reduce the likelihood of implantation. When taken as directed, it is over 99% effective.
