What structure stores mature sperm?

Question

Quizplus · Accepted Answer

The epididymis is a single-coiled duct that forms a ridge adhering to the posterior side of each testis. Sperm mature and are stored here. However, sperm are immature when they first arrive at the head of the epididymis from the efferent ductules. It takes approximately 20 days for sperm to travel from the head to the tail. All along the way, the epididymis reabsorbs excess water secreted by the testes. Once the sperm reach the tail of the epididymis, they are stored. Here, sperm remain viable for 40 to 60 days. If not ejaculated, sperm disintegrate and the epididymis reabsorbs them.
