Spermatorrhoea is an involuntary discharge of semen without an erection or an orgasm (without any sexual activity). If spermatorrhoea happens at night due to an erotic dream, the person is said to have wet dreams. In spermatorrhoea, the discharge contains sperms which makes it different from other emissions. Sperms are those elements of the semen, which are responsible for fertilization of the egg in females, leading to pregnancy.

Spermatorrhoea is a disorder in which men experience unprompted (involuntary) ejaculation i.e, discharge of semen without any sexual activity.

Imbalance of emotions, alcohol consumption, are among some of the causes of Spermatorrhoea. Some men suffer from ejaculation during sleep. Frequent spermatorrhoea in a male can cause adverse effects on the body. It is believed that spermatorrhoea occurs due to excess production of sperms in the body, however, no conclusive research is available on the same. Men often experience Spermatorrhoea during adolescence, as in this age the hormone levels increase leading to an increase in semen production. In Spermatorrhoea, the excess semen is discharged from the body through ejaculation.
