The seminal vesicles and prostate gland play a crucial role in the process of ejaculation by contributing fluid that nourishes and transports sperm. The seminal vesicles produce a significant portion of the seminal fluid, which contains nutrients like fructose that provide energy for the sperm. This fluid also contains substances that help to neutralize the acidity of the female reproductive tract, enhancing sperm viability.

The prostate gland further augments this fluid, contributing additional enzymes and citric acid, which plays a key role in the liquefaction of semen after ejaculation, allowing sperm to swim effectively. Together, these glands ensure a suitable environment for sperm, increasing the chances of successful fertilization.

In contrast, the epididymis serves primarily as a storage site for sperm where they mature, while Leydig cells are involved in testosterone production, but do not contribute directly to the ejaculate. The scrotum and testes are essential for sperm production and maintenance of optimal temperature but do not add secretions to the ejaculate. Lastly, although the vas deferens and urethra are involved in the transport of sperm during ejaculation, they also do not add any secretions.
