Testis proper

The testis proper is composed primarily of the convoluted portions of the seminiferous tubules, the exocrine portion of the gland. Each tubule is surrounded by layer of myoid cells called the tunica propria. Leydig (interstitial) cells constitute the endocrine division of the testis and are located in the connective tissue stroma between the convoluted portions. Leydig cells produce androgens under the influence of luteinizing hormone from the pars distalis of the pituitary gland. 400x
