Oral Contraceptives

Oral contraceptives (birth control pills) are medications that prevent pregnancy. They are one method of birth control. Oral contraceptives are hormonal preparations that may contain combinations of the hormones estrogen and progestin or progestin alone. Combinations of estrogen and progestin prevent pregnancy by inhibiting the release of the hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH) from the pituitary gland in the brain. LH and FSH play key roles in the development of the egg and preparation of the lining of the uterus for implantation of the embryo. Progestin also makes the uterine mucus that surrounds the egg more difficult for sperm to penetrate and, therefore, for fertilization to take place. In some women, progestin inhibits ovulation (release of the egg). Most oral contraceptives contain a combination of 2 types of hormones: an estrogen and a progestin. Both of these hormones are naturally found in women’s bodies. There are many different types of estrogens and progestin’s, and different types of pills contain different combinations, but they all work similarly. Some pills contain only progestin, sometimes called the “mini-pill.” The most important requirement for women taking oral contraceptives is that they must remember to take them every day at approximately the same time of day. Oral contraceptives are not a good form of birth control when doses are missed frequently. Oral contraceptives (birth control pills) are medications that prevent pregnancy.
