The Birth Control Pill
“The Pill”
What is it?
The pill is usually a combination of two female
hormones. They are similar to the natural
hormones that control a woman’s menstrual
cycle.
How effective is it?
When taken correctly, it is 98-99% effective.
How does it work?
When a woman takes birth control pills:
♦ Her ovaries stop releasing eggs
♦ The mucus in her cervix gets thick, making it
harder for sperm to enter
♦ The lining of the uterus gets thinner, making
it hard for a fertilized egg to attach to the
wall.
