Follicle-stimulating hormone (FSH) and testosterone are the essential hormones driving spermatogenesis [5,11]. Testosterone is produced by the Leydig cells under luteinizing hormone (LH) stimulation. WebFSH enters the testes and stimulates the Sertoli cells to begin facilitating spermatogenesis using negative feedback, as illustrated in Figure 1. LH also enters the testes and stimulates the interstitial cells of Leydig to make and release testosterone into the testes and the blood.
