- A A - GnRH, B-PRL, C - ICSH
- B A - GnRH, B - ICSH, C - ISH
- C A - GnRH, B - FSH, C - LH
- D A-GnRH, B-FSH, C - LHH
Answer & Solution
Correct Answer
(C) A - GnRH, B - FSH, C - LH
Step-by-step Solution
Detailed explanation
(C) A - GnRH, B - FSH, C - LH,
Hypothalamus gland secretes GnRH (Gonadotropin releasing hormone) it stimulates pituitary gland to release FSH (follicle stimulating hormone) and LH (luteinising hormone). FSH stimulates ovarian follicles to grow while LH (also called interstitial cell stimulating hormone) stimulates Leydig's cells to secrete testosterone.
