Exercise 5

Allison Cavanaugh is a 24-year-old female who has been experiencing painful and heavy-flow menses. At a recent visit to her gynecologist, she was diagnosed with endometriosis. The physician writes a prescription for an oral contraceptive containing estrogen and progestin and explains that this might help Allison's condition by:
A) Increasing the frequency of ovulation
B) Increasing the amount or thickness of cervical mucus
C) Decreasing the amount of pituitary hormones released
D) Creating a thin, atrophic endometrium not conducive to sustaining a fertilized ovum
