The testes are located outside the abdominal cavity within the scrotum because:
AThe scrotum allows easy hormone release
BThe scrotum provides better blood supply
CThe scrotum maintains a temperature 2–2.5°C lower than internal body temperature, necessary for spermatogenesis
DThe scrotum protects against infection
Answer & Solution
Correct answer: C. The scrotum maintains a temperature 2–2.5°C lower than internal body temperature, necessary for spermatogenesis
Spermatogenesis is temperature-sensitive — it requires a temperature **2–2.5°C below core body temperature**, which the scrotum provides by housing the testes outside the abdominal cavity.
