Early ejaculation is the release of semen before a man or his partner would like. It is the most common sexual disorder impacting men under 40. Between 30 to 70% are estimated to experience early ejaculation at some time in their lives.
Men may struggle with early ejaculation throughout their lives or acquire early ejaculation despite having successful sexual relationships in the past.
Many people use the terms early ejaculation and premature ejaculation interchangeably. However, others suggest that early ejaculation is only an occasional problem rather than a chronic one. Early ejaculation is also called rapid ejaculation, premature climax, rapid climax, and ejaculation praecox.
