Which of the following describes the function of the scrotum that houses the testes?
To keep the testes cool for sperm production
In human males the testes lie outside the abdominal cavity in a pouch of skin called the scrotum.
Sperm formation needs a temperature about 2–3 °C lower than the normal body temperature. By keeping the testes outside the abdomen, the scrotum maintains this lower temperature, so its function is to keep the testes cool for sperm production.
Testosterone is produced by the interstitial (Leydig) cells of the testes, not by the scrotum. Sperm are stored mainly in the epididymis, and semen is formed only when sperm mix with secretions of the seminal vesicles and prostate gland, not stored in the scrotum.
The scrotum’s position does not shorten the path of sperm; sperm actually travel a long route through the epididymis, vas deferens and urethra.
Hence, To keep the testes cool for sperm production.
