Question

In most mammals, the testes are located in scrotal sac for _________.

• A. More space to visceral organs
• B. Spermatogenesis
• C. Sex differentiation
• D. Independent functioning of kidney

Answer 1

Answer: (B)

Spermatogenesis

In mammals, scrotal sacs (containing testes) act as thermoregulator, maintaining the temperature of the testes $2^{o}C$ lower than that of the body. This temperature is required for the spermatogenesis to occur otherwise, the sperms could be destroyed by high temperature, resulting in sterility.
