Premature ejaculation is one of the most common sexual dysfunctions in men.

According to the International Society for Sexual Medicine, PE has been defined as a male sexual dysfunction characterized by (1) Ejaculation that always or nearly always occurs prior to or within one minute of vaginal penetration, either present from the first sexual experience or following a new bothersome change in ejaculatory latency. (2) Inability to delay ejaculation on all or nearly all vaginal penetrations. (3) Negative personal consequences, such as distress, bother, frustration &/or the avoidance of sexual intimacy.
