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?

पर्याय

• no effect; germinal epithelium will carry out normal spermatogenesis.

• germinal epithelium will produce a large quantity of androgen secretion.

• germinal epithelium will produce more sperms.

• germinal epithelium will degenerate, resulting in sterility.

Answer 1

Germinal epithelium will degenerate, resulting in sterility.

Explanation:

In most mammals, testes are located in the scrotum, which keeps their temperature about 2 - 2.5°C lower than the abdominal temperature. This lower temperature is necessary for normal spermatogenesis. If the scrotal temperature is artificially maintained at the abdominal temperature, the germinal epithelium of the testes degenerates, causing sterility because sperm production is impaired at the higher temperature.
