MEDICAL PHYSIOLOGY

Detailed explanation-1: -Sperm Storage. The cauda epididymis functions as a storage location for functionally mature sperm cells prior to ejaculation [22]. At a given time, between 50 and 80% of sperm in the epididymal lumen are located in the cauda epididymis, depending on species [2].

Detailed explanation-2: -The epididymis consists of three parts: head, body, and tail. The head of the epididymis is located on superior pole of testis. It stores sperm for maturation. The body of the epididymis is a highly convoluted duct which connects the head to the tail of the epididymis.

Detailed explanation-3: -The epididymis is found on the posterior surface of the testes, and sits along the entire length of the posterior testes.

Detailed explanation-4: -The cauda epididymis can store enough sperm for two to three normal semen samples. This is substantially less sperm than is stored in the cauda of many other species.
