Spermatogenesis is affected by temperature and is involuntarily controlled by the . Sonography of. Scrotum and Testes. .. Anatomy. . The scrotum is divided by the midline raphe. Each half of the scrotum contains a spermatic cord, testis, and epididymis. The testes descend into the scrotum at approximately the 28th gestational week via the inguinal canal through the peritoneal recess, which is called the processus vaginalis. The processus vaginalis gradually closes through infancy and childhood. The testis is covered by a visceral layer of tunica vaginalis, except where in contact with epididymis, and by the tunica albuginea. The posterior surface of the tunica albuginea extends into the testis to form the mediastinum testis. This is seen as a middle echogenic line on longitudinal US of the testis The testis has lobules containing the seminiferous tubules. Testicular lobules are occasionally identified as lines radiating from the mediastinum testis. Neil Gesundheit, M.D., M.P.H.. neil7@stanford.edu. Testicular Physiology: Objectives.
