Which statement about the use of combined oral contraceptives in adolescents with dysmenorrhea reflects the most important rationale?

• A. They regulate menstrual flow
• B. Hormones suppress ovulation, reduce endometrial growth and total prostaglandin production
• C. They increase menstrual flow
• D. They provide pregnancy protection

Answer: (B)

In adolescents with dysmenorrhea, the key idea is that combined oral contraceptives relieve pain by tamping down the processes that drive menstrual cramps. The hormones in these pills suppress ovulation and stabilize the endometrium, which means less endometrial shedding and a lower overall production of prostaglandins in the uterus. Prostaglandins, especially in the uterus, promote heavy contractions and cramping, so reducing their production leads to fewer and milder cramps. Pregnancy protection is a beneficial side effect, but the primary benefit for dysmenorrhea is the hormonal suppression of ovulation, decreased endometrial growth, and reduced prostaglandin activity that together lessen uterine contractions and pain.
