Question

In most of the mammals, the testes remain enclosed in an extra-abdominal sac, the scrotum, where the temperature is lower than that in the abdomen. What will happen if the temperature of the scrotum is artificially maintained to the level of abdominal temperature?

• A. No effect; germinal epithelium will carry out normal spermatogenesis
• B. Germinal epithelium will produce a large quantity of androgen secretion
• C. Germinal epithelium will produce more sperms
• D. Germinal epithelium will degenerate, resulting in sterility

Answer 1

The correct option is D Germinal epithelium will degenerate, resulting in sterility

The scrotum is a pouch, suspended from the groin, that contains the testes and some of the male sex accessory ducts. One function of the scrotum is to help maintain the temperature necessary for spermatogenesis by locating the testes outside of the body cavity. The temperature in the human scrotum is 3.1 °C (5.6 °F) lower than the normal temperature within the body (37 °C, or 98.6 °F). If the temperature is maintained to the level of abdominal temperature, The germinal epithelium will degenerate resulting in sterility.

So the correct option is 'germinal epithelium will degenerate, resulting in sterility'.
