4. What is the significance of the testes being located in the scrotal sacs outside the abdomen. Can there be any abnormal situation regarding their location? If so, what is that and what is the harm caused due to it?

Solution:-

The two testes are oval organs that are housed in the scrotum, a thin-walled skin sac.

The testes are enclosed within the abdomen during the embryonic stage. When they do not descend into the scrotum just before birth, an aberrant condition occurs, resulting in sterility, or the inability to generate sperms.

Sperm are created in the testes at a temperature that is 2 to 3 degrees Celsius cooler than the body temperature. The temperature is controlled in an unusual way by the movements of the scrotum wall.

The skin of the scrotum loosens in warmer weather, causing the testes to dangle down away from the body. When it’s cold outside, the skin folds inward and pulls the testes closer to the body for warmth.
