Male external genital organs
The scrotum is a cutaneous fibromuscular sac containing the testes and lower parts of the spermatic cords. It is made up of the skin, the dartos muscle, the external spermatic fascia, the cremasteric muscle and fascia and the internal spermatic fascia. The left side of the scrotum is usually lower because the left spermatic cord is longer. A fibromuscular ‚Äòscrotal ligament' extends from the dartos sheet to the inferior pole of testis, which may play a role in thermoregulation of the testis. Due to the presence of numerous sweat glands, the scrotum is a common site for sebaceous cysts.
The penis is the male organ of copulation. It has a root, that is attached to the perineal membrane and a free part that is seen in the specimen. The terminal portion of the penis is known as the glans penis. Throughout its length, it is traversed by the urethra.
The spermatic cord suspends the testis in the scrotum and extends from the deep inguinal ring to the posterior aspect of the testis. It consists of the vas deferens, the arteries, the pampiniform venous plexus, the nerves and the lymphatic vessels.
The testes are male gonads. They are placed within the scrotal sacs. They consist of numerous seminiferous tubules that are made up of spermatogenic cells and sertoli cells. The Leydig cells between the seminiferous tubules secrete the testosterone hormone that is responsible for the spermatogenesis.
