class 12th CBSE Biology sample paper

Answer 1

Failure of testes to descend into the scrotum causes sterility because sperm formation does not occurs at the abdominal temperature.
In scrotum, the testes remains at a temperature 2-3 degree lower than that of body temperature which is suitable for sperm formation.

If the favorable temperature is not provided by the scrotum to the testis than it will not or stop producing sperms.

Answer 2

Testes forms sperms in males
Like the position of ovaries in females, the testes in males too remain in the abdomen and gets into the scrotum through the inguinal canal shortly before birth. If this fails to happen, sperms are not produced in the male. Thus he cannot reproduce, hence he is sterile.

Thus if the testes fail to descend into the scrotal sac, it leads to sterility
