MCQ
At menopause, there is a rise in urinary excretion of:
  • A
    LH
  • B
    STH
  • C
    FSH
  • D
    Both A and C
✓

Answer

  1. Both A and C

Explanation:

Estrogen hormone is used to inhibit the production of FSH and LH in females.

During menopause, the level of estrogen in the blood decreases, so estrogen can not inhibit the FSH and LH at the time of menopause.

Therefore, FSH and LH are produced after menopause in large quantities, which are excreted out in the urine.
