Question

Oral contraceptive pills work by delivering synthetic progestins to a woman every day. Describe why this is an effective method of birth control.

Answer 1

If you take progestins every day, your body takes it as a sign to not ovulate.

If you don't ovulate, there's no way sperm can reach any ovule because it's not there.

Also, the uterus walls get widen, and this doesn't let the sperm to get into the uterus.
