Birth control pills are oral contraceptives taken by women to prevent pregnancies. The most effective forms of birth control pills contain estrogen and a small amount of progestin (a synthetic hormone that mimics the effects of progesterone). Although the most effective forms of oral contraceptive for women contain estrogen and progestin, some birth control pills contain a small dose of progestin only. This is because there are many risks and side effects associated with estrogen.Which of the following statements is NOT a reason for using a progestin-only oral contraceptive? Select one: a. Progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum. b. Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen. c. Progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary. d. Progesterone suppresses the production of GnRH in the hypothalamus.

Envision yourself as a physician whose patients sometimes ask about birth control. Provide a contraceptive method for each of the following patients, and explain why it would be appropriate: couple A, a man and woman who have intercourse regularly but never want to have children; couple B, a man and woman who have intercourse regularly and want to have children someday; and person C, a single woman who occasionally has intercourse with single men and does not wish to become pregnant. Be sure to include the level of protection against STDs that each person is likely to need.

Some couple practice natural family planning (also known as the rhythm method of birth control), which involves abstaining from sexual intercourse during the time that a woman can become pregnant in her menstrual cycle. The egg only survives in the fallopian tube from 24 hours after ovulation, so conception can only happen during a 24-hour period each month. However, this form of contraceptive is very unreliable and is not recommended for couples who are actively trying to avoid pregnancy. Which of the following is NOT a reason why this form of birth control is unreliable? A. Sperm can survive in the fallopian tubes for 3 to 5 days. B. Ovulation can be affected by stress or illness. C. Women always ovulate on the same day of their menstrual cycle every month. D. It is difficult to predict exactly when in her cycle a woman ovulates.
