By the Leydig cells and FSH stimulates the secretion of by the Sertoli cells is D testosterone, estrogen. The focus controller of LH and FSH secretion is gonadotropin-releasing hormone (GnRH, also known as LH-releasing hormone).
LH promotes Leydig cell T production, and FSH promotes in Sertoli cells, in synergy with T, the display of regulatory molecules and nutrients needed for the upkeep of spermatogenesis. Hence, both T and FSH regulate spermatogenesis indirectly through Sertoli cells.
Thus, By the Leydig cells and FSH stimulates the secretion of by the Sertoli cells is D testosterone, estrogen. The focus controller of LH and FSH secretion is gonadotropin-releasing hormone.
