• A. Man will die.
• B. The development of male secondary sex character will not take place.
• C. The development of male reproductive system will not take place.
• D. The formation of sperms will not take place.

Answer 1

Answer: (D)

The formation of sperms will not take place.

In mammals, the process of spermatogenesis or the formation of sperm requires a lower temperature than the normal body temperature to produce viable sperms. Hence, the sperms are stored outside the body in a sac-like structure called scrotum.
So, if the testes do not move from abdominal cavity to the scrotal sac, the sperms will not be formed.
Thus, the correct answer is option D.
