Each of the two testes (singular, testis) consists of the following structures: The tunica vaginalis is a two-layer outer serous membrane surrounding  each testis. The tunica albuginea lies inside the tunica vaginalis and protrudes inward,  dividing each testis into compartments called lobules. One to four tightly coiled tubes, the seminiferous tubules, lie inside each  lobule. The seminiferous tubules are the sites of sperm production  (spermatogenesis). The tubule is lined with spermatogenic cells, which form

The coiled seminiferous tubules inside each lobule unite to form a straight tube, the tubulus rectus. • The rete testis is a network of tubes formed by the merging of the tubules recti from each lobule. • The efferent ducts transport sperm out of the testis (from the rete testis) to the epididymis. • Interstitial cells surrounding the seminiferous tubules secrete testosterone and other androgen hormones....
