Explanation
Prostate Gland's Role in Reproduction
Steps:
- Recall the male reproductive system: glands like prostate, testes, and seminal vesicles contribute to semen formation.
- Identify prostate location: surrounds the urethra below the bladder.
- Link function to sperm viability: prostate secretes fluid that nourishes and protects sperm during ejaculation.
- Eliminate unrelated roles: match choices to known gland functions for accuracy.
Why C is correct:
- The prostate gland produces alkaline fluid that forms part of semen, providing nutrients and mobility for sperm, as defined in human anatomy.
Why the others are wrong:
- A: Adrenaline is produced by the adrenal glands, not the prostate.
- B: Testosterone is mainly produced by the testes (Leydig cells).
- D: Mature sperm are stored in the epididymis, not the prostate.
Final answer: C
