To understand semen leakage or night discharge, you should first understand more about semen. When the man ejaculates, the whitish fluid that gets released from the penis is called semen. Primarily seminal fluid produced by seminal vesicles and the prostate. The seminal vesicles are the tiny glands located behind the prostate. A certain percentage of semen is made of sperms as well. The semen is generally coming out through the penis during sex or masturbation. However, sometimes the semen can exit the end of the penis without being aroused sexually.
