Question

Describe the male reproductive system of a man with a suitable diagram.

Answer 1

Male Reproduction System: 

• The male reproductive system consists of primary reproductive and accessory reproductive organs. Primary sex organs are a pair of testes or male gonads. Accessory reproductive organs are mainly scrotal sac, epididymis, vas deferens, penis, prostate gland and Cowper’s glands. 

Testes: 

• An adult man has a pair of testes (oval bodies suspended outs the body in the scrotum). 
• The wall of tests is an elastic covering of thin and hairy and thick inner subcutaneous layer of unstriated muscle fibres which is known as Dartos muscle. 
• In each half of scrotal sac, a tuft of rod-shaped striated muscles fibres are found. It connects the subcutaneous layer with abdominal subcutaneous muscle and known as Cremaster muscle. 
• Each cavity of the scrotal sac is connected to the abdominal cavity with the help of a white Inguinal canal. In adult mammals, testes are ex-abdominal which are found outside the abdominal cavity in the testes sacs or scrotal sacs. 
• The spermatogenesis in the testes: needs less temperature and the temperature of the scrotal sacs is 33 to 35°C which is 2 to 4o C less than the body temperature. 
• The testis descends into the scrotal sac through an inguinal canal. The testicular artery, testicular vein & the testicular nerve also descend into the scrotal sac in the form of a spermatic cord. 
• Each testis is attached in the scrotal sac with the help of a gubernaculum. Both the spermatic cord & the gubernaculum are provided with elastin fibres. 
• If the testes fail to descend into the scrotal sacs, the spermatogenesis gets arrested due to a high temperature which called cryptorchidism.
