Which part of the male reproductive system stores sperm before ejaculation?

Correct Answer: D

Rationale: The correct answer is D: Epididymis. The epididymis is a coiled tube located on the back of each testicle where sperm mature and are stored before ejaculation. It allows for sperm to gain motility and fertilizing ability. The other choices (A, B, C) are incorrect because the vas deferens is the tube that carries sperm from the epididymis to the urethra, seminal vesicles produce seminal fluid that nourishes and transports sperm, and the prostate gland secretes fluids that protect and nourish sperm, but none of these structures store sperm before ejaculation.
