In brief: Prevent egg release

Ovral (ethinyl estradiol and norgestrel) and all birth control pills contain hormones that prevent ovulation (release of egg by your ovary).
They also cause the mucous in your cervix (the opening to uterus or womb) thicker which make it hard for sperm to enter. It thins the lining of the uterus which makes it an unpleasant environment for a fertilized egg.
