*Follicle stimulating hormone stimulates spermatogenesis by stimulating the sertoli cells to complete the development of spermatozoa from spermatids*.
*Luteinising hormone stimulates the synthesis of the hormone "testosterone" by the leydig (interstitial cells) of the testis*. Testosterone is a steroid hormone and is made from cholesterol, It stimulates growth and development of the germinal epithelial cells (spermatogonia) to form sperms,and also works with follicle stimulating hormone to stimulate sertoli cells.
