Question

The lower temperature in the scrotum is the functional advantage of having human testes in the scrotum rather than in the abdomen. Sperm production requires a temperature slightly lower than the normal body temperature, which is maintained by the scrotum's position outside the body. If the testes were located in the abdomen, the internal body temperature would be too warm for proper sperm production.
