Expert Answer:

The testes are the essential sex organs (gonads) in the male that serve to produce the male gametes (sperm) and the male sex hormone testosterone. The accessory male reproductive structures aid in the maturation, nourishment and transport of the sperm through the male reproductive system and into the female’s body for fertilisation.

When released from the testis, the sperm spend two to 10 days passing through the epididymis. During this journey, the sperm mature and gain the ability to move (swim or become motile).

When ejaculation starts, sperm are transported from the tail of the epididymis, via the vas deferens, to the urethra in the penis. As sperm pass through the different tubes, fluid from the seminal vesicles, Cowper’s and prostate glands is added to the sperm. The mixture is then called semen. Over 90% of the semen is produced from the prostate and seminal vesicles and not from the testis.
