What is the function of GnRH in the process of spermatogenesis?

Options

  1. AStimulate the secretion of androgens
  2. BActs at the Leydig cells
  3. CStimulate secretion of two gonadotropins
  4. DHelps in the process of spermiogenesis

Correct answer

C. Stimulate secretion of two gonadotropins

Step-by-step solution

Spermatogenesis starts at the age of puberty due to significant increase in the secretion of gonadotropin releasing hormone (GnRH). This, if you recall, is a hypothalamic hormone. The increased levels of GnRH then acts at the anterior pituitary gland and stimulates secretion of two gonadotropins – luteinising hormone (LH) and follicle stimulating hormone (FSH). LH acts at the Leydig cells and stimulates synthesis and secretion of androgens. Androgens, in turn, stimulate the process of spermatogenesis. FSH acts on t
