Answer

The menstrual cycle can be divided into 3 physiologic phases: follicular, ovulatory, and luteal. Each phase has a distinct hormonal secretory milieu. Consideration of the target organs of these reproductive hormones (hypothalamus, pituitary, ovary, uterus) is helpful for identifying the disease process responsible for a patient’s amenorrhea.
