Concepts Covered - 1
Hormonal Control of Spermatogenesis
- Spermatogenesis starts at the age of puberty due to a significant increase in the secretion of gonadotropin-releasing hormone (GnRH).
- This is a hypothalamic hormone.
- The increased levels of GnRH then act at the anterior pituitary gland and stimulate 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 the secretion of some factors which help in the process of spermiogenesis.
