A nocturnal emission involves either ejaculation during sleep for a male, or lubrication of the vagina for a female. It is also called a "wet dream", or a spontaneous orgasm.
Nocturnal emissions are most common during adolescence and early young adult years. However, nocturnal emissions may happen any time during or after puberty. The emission may happen with or without an erection, and it is possible to wake up during, or to simply sleep through, the ejaculation. Though nocturnal emissions are mostly attributed to, and more noticeable by men, women are also capable of having them.[1] Urination may also occur after the emission of semen in males.[2]
