Structures of the male reproductive system include testes, accessory glands, penis, semen, and hormones. Testes. The testes are located outside the abdominal cavity, suspended in a sac called the scrotum, which is between the thighs. Each of the two testis (singular) is surrounded by a tough fibrous connective tissue capsule. The word for the testes originated in the Greek and so named for its oval shape â orchis.
Tunics and Mediastinum. Each testis is suspended in a outpouching of the peritoneal cavity. This cavity, like the rest of the peritoneum, is lined by a serosa consisting of mesothelial cells supported by a fibrous connective tissue. Around the testis, the parietal peritoneum is named tunica vaginalis while the visceral peritoneum is named tunica albuginea.
