Give the names and functions of the hormones involved in the process of spermatogenesis. Write the names of the endocrine glands from where they are released.
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 the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis
