Premature ejaculation (
PE) occurs when a man experiences
orgasm and
expels semen soon after
sexual activity and with minimal
penile stimulation. It has also been called
early ejaculation, rapid ejaculation, rapid climax, premature climax, and (historically)
ejaculatio praecox. There is no uniform cut-off defining "premature", but a consensus of experts at the International Society for Sexual Medicine endorsed a definition including "ejaculation which always or nearly always occurs prior to or within about one minute". The
International Classification of Diseases (ICD-10) applies a cut-off of 15 seconds from the beginning of
sexual intercourse.
