Question

Which of the following is INCORRECT about the male reproductive system?

• A. The testes are present within the abdomen during the embryonic stage
• B. The testes descend into the scrotum shortly after birth
• C. Failure of testes to descend into the scrotum causes infertility
• D. Sperm maturation cannot happen at a high body temperature

Answer 1

The correct option is B

The testes descend into the scrotum shortly after birth

During the embryonic stage of a human male, the testes are present within the abdomen. Shortly before birth (and not after birth), the testes descend into a thin-walled sac of skin called the scrotum. If this descent fails to occur, it leads to sterility, which means that the individual would be incapable of producing sperm. This descent is absolutely necessary as the production and maturation of sperm requires a temperature that is 2-3 degree Celsius lower than the normal body temperature.
