**Core Concept**
The epididymis is a long, coiled tube where sperm mature and gain the ability to fertilize an egg. Sperm transit through the epididymis is a critical step in their development and maturation.

**Why the Correct Answer is Right**
Sperm remain in the epididymis for approximately 12-14 days, during which time they undergo maturation, including changes in motility, morphology, and the ability to fertilize an egg. This process is facilitated by the secretion of enzymes and proteins by the epididymal epithelium, which help to break down and remove excess cytoplasm and other cellular components from the sperm. The epididymis also provides a suitable environment for sperm to develop resistance to capacitation, a process that allows them to fertilize an egg.

**Why Each Wrong Option is Incorrect**
**Option A:** 2 hours - This is an implausibly short amount of time for sperm to mature in the epididymis.
**Option B:** 2 weeks - While sperm do spend several days in the epididymis, 2 weeks is longer than the actual duration.
**Option C:** 1 month - This is significantly longer than the actual duration of sperm stay in the epididymis.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that sperm maturation in the epididymis is a gradual process that allows sperm to develop the necessary characteristics for fertilization. This process can be affected by various factors, including hormonal imbalances, infections, and genetic disorders.

**Correct Answer:** C. 12-14 days
