Question

Temperature in scrotum necessary for sperm formation should be

• A. 2${}^o$C above body temperature
• B. 2${}^o$C below body temperature
• C. 4${}^o$C above body temperature
• D. 4${}^o$C below body temperature

Answer 1

The correct option is B 2${}^o$C below body temperature

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. The testes of human males are extra-abodominal because it descends into the scrotal sacs.

Thus, the correct answer is '2${}^o$C below body temperature'.
