Testes are extra-abdominal in position." Which of the following is the most appropriate reason?"

Options

A. Narrow pelvis in males
B. Special protection for testes
C. Prostate gland and seminal vesicles occupy maximum space
D. `2.0-2.5^(@)C` lower than the normal body temperature

Answer

D

Explanation

• The male reproductive system is located in the pelvis region. It includes a pair of testes along with accessory ducts, glands and the external genitalia.
• The testes of man and rabbit are situated outside the abdominal cavity within a pouch called scrotum or scrotal sac. The scrotum helps in maintaining the low temperature of the testes (`22.5^(@)C` lower than the normal internal body temperature) necessary for spermatogenesis.
