Which of the following is NOT a function of the epididymis?

Explanation:
The epididymis is where sperm mature, gain the ability to swim, and become capable of fertilization after leaving the testes. As sperm pass through the epididymal duct, they undergo changes in their membranes and external proteins due to the secretions of the epididymal lining, which is why they acquire motility and fertilizing capability. It also serves as a conduit, with smooth muscle contractions helping move sperm from the testes toward the vas deferens. A major function is storage, especially in the tail of the epididymis, where mature sperm can be kept for some time before ejaculation. Decomposition of sperm is not a normal function of the epididymis; while older sperm may be cleared, the primary roles involve maturation, transport, and storage, not breakdown.
