What is the significance of epididymis in male fertility?

Explanation

### Step-by-Step Solution:

1. **Understanding the Epididymis**: The epididymis is a long, coiled tube located at the back of each testicle. It is an essential part of the male reproductive system.

2. **Maturation of Sperm**: One of the primary functions of the epididymis is to facilitate the maturation of sperm (spermatozoa). As sperm pass through the epididymis, they undergo physiological changes that are crucial for their development.

3. **Increased Motility and Fertilizing Capability**: During their time in the epididymis, sperm gain increased motility, which is essential for their ability to swim and reach the egg. Additionally, the fertilizing capability of the sperm is enhanced, making them more effective in the fertilization process.
