GnRH or gonadotropin releasing hormone is a hypothalamic hormone. Spermatogenesis starts at puberty due to its significant increase.Its increased levels acts on  anterior pituitary gland and stimulates the secretion of LH and FSH. LH acts on the Leydig cells and stimulates synthesis and secretion of androgens. FSH acts on Sertoli  cells, which stimulates the secretion of some factors that help in spermiogenesis.
