Sperm Transport
Sperm is produced in the testes. From there, sperm travels into a small gland that is located just outside the testes called the epididymis. Approximately 700 million sperm are stored in the epididymis. The average transit time of sperm across the length of the epididymis is approximately 12 days.

The coiled tubule of the epididymis at the very end joins the ‘vas’ or ‘vas deferens’. Vas transports the sperm into the body where it enters the prostate gland. The prostate gland is responsible for making the seminal fluid along with contribution from the seminal vesicles. This fluid carries the sperm through urethra in the act of ejaculation
