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

The epididymis plays several vital roles in the reproductive system, especially in relation to sperm. Its primary functions include the maturation, transport, and storage of sperm cells.

The maturation of sperm occurs within the epididymis, where they gain motility and the ability to fertilize an ovum. As sperm travel through the epididymis, they undergo cellular changes that prepare them for their role in reproduction.

Additionally, the epididymis serves as a crucial transit system for sperm, allowing them to move from the testicles to the vas deferens. This passage is important for ensuring that sperm are fully matured and ready for ejaculation.

Moreover, the epididymis effectively stores sperm until they are needed for fertilization. This storage is essential for maintaining a reserve of viable sperm that can be used when required.

In contrast, the idea of the epididymis serving a function related to the decomposition of sperm is inaccurate. Although some sperm can break down in the epididymis over time if not ejaculated, this process is not considered a primary function of the epididymis itself. Instead, it is a part of the natural lifecycle of sperm when they are not used. Thus, the presence of a "
