Answer: Testes.
- A Prostate gland
- B Epididymis
- C Testes
- D Seminal vesicles
Correct answer: C. Testes
Explanation: Sperm are produced in the testes (spermatogenesis), specifically in the seminiferous tubules. The testes are located in the scrotum outside the body because sperm production requires 2-3 degrees Celsius lower than body temperature.
The human male reproductive system: sperm formed in the testis mature in the epididymis and travel via the vas deferens, mixing with secretions of the seminal vesicle, prostate and bulbourethral glands. Image: Wumingbai, CC BY-SA 4.0, via Wikimedia Commons.
