The epididymis is a coiled tube located on the back of each testicle. It serves as a storage and maturation site for sperm. Sperm produced in the testicles are immature and incapable of fertilization; they travel to the epididymis to mature over several weeks. Think of it as a sperm finishing school, where sperm learn how to swim and fertilize an egg. 🎓 It's essential for male fertility.
