Mainly which type of hormones control the menstrual cycle in human beings?

  1. FSH
  2. LH
  3. FSH, LH, estrogen
  4. progesterone

Answer

(3) FSH, LH, estrogen

Solution

As per NCERT, the secretion of gonadotropins (LH and FSH) increases gradually during the follicular phase and stimulates follicular development as well as secretion of estrogens by the growing follicles.

⇒ The LH surge in the middle of the cycle induces ovulation; the changes in the ovary and the uterus are thus induced by pituitary and ovarian hormones.

∴ FSH, LH and estrogen together mainly control the menstrual cycle.

Answer: (3)
