Question

The testes in human are situated outside the abdominal cavity inside the scrotum. This is to

• A. Provide a secondary sexual feature to exhibit the male sex
• B. Maintain the scrotal temperature lower than the internal body temperature
• C. Escape any possible compression of the testes by other visceral organs
• D. Provide more space for the growth of epididymis

Answer 1

The correct option is B Maintain the scrotal temperature lower than the internal body temperature

In all mammals, the testes descend into the scrotum, which is outside the body cavity. Here, the temperature is 2-3 degree Celsius lower than the inside of the body. This is necessary for the spermatogenesis as the sperm cannot form at temperatures as high as those in the body core.
Therefore, the correct answer is option B.
