Birth control pills were invented as one of the components of family planning. Antifertility drugs are chemical substances which suppress the action of hormones that promote pregnancy. These drugs actually reduce the chances of pregnancy and act as a protection. Antifertility drugs are made up of derivatives of synthetic progesterone or a combination of derivatives of estrogen and progesterone.
Antifertility drugs are actually synthetic hormones. When progesterone pills are taken, the mucus in the cervix gets thickened. This makes it very difficult for sperm to enter the uterus and fertilize the egg and hence chances of pregnancy are reduced. Progesterone is a hormone which suppresses ovulation in women. The synthetic progesterone derivatives are more potent as compared to natural progesterone. Norethindrone is an example of synthetic progesterone which is one of the most commonly used antifertility drugs. Ethynylestradiol is a combination of derivatives of estrogen and progesterone.
