Question

Which one of the following character favours the process of normal spermatogenesis in human male?

• A. Descent of tests into scrotum
• B. Infection by mumps virus during childhood
• C. Tests remain in the abdominal cavity
• D. Increased scrotal temperature

Answer 1

Answer: (A)

Descent of tests into scrotum

The sperms are produced in the testes in which the process of spermatogenesis takes place. The temperature of the scrotum is 2-3${}^o$ C less compared to the body temperature which is necessary for the maintenance of the optimum temperature for spermatogenesis. So, it is necessary that the testes must descend down into the scrotum.

Thus, the correct answer is option A.
