Final answer:

The testes are located in the scrotum outside the torso to provide an optimal temperature for sperm production.


Explanation:

Sperm production in the seminiferous tubules is very sensitive to temperature. The testes are located outside the torso in the scrotum because the temperature there is about 2 degrees Celsius lower than core body temperature, which is optimal for spermatogenesis. The scrotum regulates its internal temperature to ensure the proper environment for sperm production.
