Sample practice questions
Easy
1. Sperm cells are produced through meiosis in which organ?
The testes
The ovaries
The prostate gland
The epididymis
Answer: The testes — The testes produce sperm cells through meiosis (spermatogenesis) and also produce testosterone.

Medium
3. Why are the testes located outside the main body cavity, within the scrotum?
This keeps them slightly cooler than core body temperature, which is optimal for sperm production
This protects them from the female reproductive tract
This allows testosterone to be produced faster
This has no functional significance
Answer: This keeps them slightly cooler than core body temperature, which is optimal for sperm production — Sperm production (spermatogenesis) functions best at a temperature slightly below core body temperature, which the external position of the scrotum provides.
