Why are the Testes Located Outside the Abdominal Cavity in the Scrotal

Question

Why are the testes located outside the abdominal cavity in the scrotal sac
A)to permit temperature-sensitive spermatogenesis
B)to protect the gonads against injury
C)to permit testosterone secretion
D)to maintain the testes at a higher than normal body temperature

Accepted Answer

The testes are located outside the abdominal cavity in the scrotal sac to permit temperature-sensitive spermatogenesis. Sperm production requires a lower temperature than the normal body temperature, which is maintained by the scrotum's ability to contract or relax in response to temperature changes.
