Definition: Spermological refers to the process of a male reproductive organ, such as the testes or prostate gland, producing and releasing sperm. Sperm is produced from the testis by an enzyme called spermatocyte, which then releases it into the surrounding environment through the urethra. Sperm are responsible for fertilizing eggs in the female reproductive system, initiating sexual reproduction in humans, and contributing to the male's ability to produce offspring.
