Question 16Explanation: The combination of amenorrhea, galactorrhea (milk production), and headaches strongly suggests hyperprolactinemia, a condition characterized by elevated prolactin levels. This can be caused by a prolactin-secreting pituitary adenoma (prolactinoma), which can also cause headaches due to mass effect. Prolactin inhibits the pulsatile releaseof GnRH, leading to decreased FSH and LH, and consequently, amenorrhea.Answer: ProlactinA 27-year-old woman presents with amenorrhea for 6 months.
