Question Detail
Question
Since formation of sperms requires a temperature below body temperature: a. scrotal sacs are between thighs b. more water intake is advised for mature males c. scrotal sacs are pouch like hanging extensions d. testes lie in scrotal sacs
Correct Answer
Option D is the correct answer.
Detailed Explanation
The key adaptation for temperature regulation is that the testes lie outside the body cavity in the scrotal sacs. The scrotum's location and its muscles allow it to move the testes closer to or further from the body to maintain the optimal temperature (about 2-3°C lower than body temperature).
Hint
Where are the testes located, and why?
