THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored.

Detailed explanation-2: -Sperm undergo final maturation during their passage through the epididymis (which can last up to 14 days) where they acquire motility and the ability to fertilize an egg. Additionally, the epididymis protects the sperm from harmful substances such as xenobiotics and oxygen radicals.

Detailed explanation-3: -The testes are where sperm are manufactured in the scrotum. The epididymis is a tortuously coiled structure topping the testis, and it receives immature sperm from the testis and stores it for several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct.
