Which structure stores and matures sperm after production?

• A. Epididymis
• B. Vas Deferens
• C. Prostate
• D. Seminal Vesicles

Answer: (A)

Sperm maturation and storage occur in the epididymis. After sperm are produced in the seminiferous tubules of the testes, they enter the epididymis, a long coiled duct along the back of the testis. As they travel from the head to the tail, they undergo functional maturation, gaining motility and the ability to fertilize an egg. The epididymal environment and its specialized epithelium support these changes, and the tail serves as a reservoir where mature sperm are stored until ejaculation. When ejaculation occurs, contractions move the sperm into the vas deferens for onward transport. The other structures don’t serve this storage-and-maturation role: the vas deferens mainly carries sperm from the epididymis during ejaculation, while the prostate and seminal vesicles add fluids to semen rather than maturing or storing sperm.
