Mode of Action of Birth Control Pills / Oral Contraceptive Pills

The Combined and Phasic Pills prevent pregnancy by

• Inhibiting the release of eggs from the ovaries (ovulation).
• Thickening the cervical mucus thus preventing the sperm from entering the uterus.
• Altering the inner environment of the uterus and making it impossible for the egg to attach to the walls of the uterus.
