The MOST important rationale for using combined oral contraceptives in an adolescent with primary dysmenorrhea includes that hormones do what?

• A. The use of oral contraceptives will regulate and lighten menstrual flow
• B. Hormones in oral contraceptives will suppress ovulation, reduce endometrial growth and total prostaglandin production
• C. Hormones in oral contraceptives will suppress ovulation, reduce menstrual flow, and increase total prostaglandin production
• D. The use of oral contraceptives will provide pregnancy protection

Answer: (B)

Primary dysmenorrhea is driven by prostaglandins produced in the endometrium, which trigger strong uterine contractions and pain. Combined oral contraceptives help by suppressing ovulation and making the endometrium thinner and more stable, which reduces the amount of prostaglandins produced and, consequently, the intensity of uterine contractions. In practical terms, this means lighter, more regular menses with less cramps. So the most important rationale is that the hormones in oral contraceptives will suppress ovulation, reduce endometrial growth, and lower total prostaglandin production. While pregnancy protection is a benefit, it is not the main reason they relieve dysmenorrhea, and increasing prostaglandin production would worsen pain, which is not what these hormones do.
