The Scrotum is a cutaneous pouch which contains the testes and parts of the spermatic cords (the spermatic cord is composed of arteries, veins, lymphatics, nerves, and the excretory duct of the testis. These structures are connected together by areolar tissue). It is divided on its surface into two lateral portions by a ridge or raphé. (Sushruta explains raphe' as "seevani" or a stitch like ridge. He has cautioned not to injure it with surgical instruments) of these two lateral portions the left hangs lower than the right, to correspond with the greater length of the left spermatic cord. The Testes (two egg-shaped structures) remain in the Scrotum, outside the body, where the temperature is about 3 degrees C Cooler than the body internal temperature (27 degrees C. sperm development in the testes requires the lower temperature.)
