Question

Why are testes in human males located outside the abdominal cavity in scrotum? 

Hint:

The scrotum's ability to regulate temperature helps ensure the optimal conditions for sperm production.

Answer 1

The testes are located outside the abdominal cavity in the scrotum to maintain a temperature lower than the body's core temperature, which is essential for the production of healthy sperm. Sperm production requires a temperature of around 2–3°C lower than the normal body temperature, and the scrotum helps regulate this temperature by contracting or relaxing in response to environmental conditions.
