Question

In mammals, maturation of sperms take place at a temperature

• A. Equal to that of the body
• B. Higher than that of the body
• C. Lower than that of the body
• D. At any temperature

Answer 1

Answer: (C)

Lower than that of the body

In mammals, maturation of sperms take place at a temperature lower than that of body. For that purpose, testes of mammals are extra-abdominal. The testes are situated outside the abdominal cavity within a pouch called scrotum. The temperature in scrotum necessary for sperm formation should be 2${}^o$C below body temperature. The slightly cooler temperature of the scrotum is necessary for the development of normal sperm.

Thus, the correct answer is 'Lower than that of the body'.
