Premature ejaculation

Premature ejaculation is when ejaculation occurs before the partner achieves orgasm, or a mutually satisfactory length of time has passed during intercourse. There is no correct length of time for intercourse to last, but generally, premature ejaculation is thought to occur when ejaculation occurs in under 2 minutes from the time of the insertion of the penis. For a diagnosis, the patient must have a chronic history of premature ejaculation, poor ejaculatory control, and the problem must cause feelings of dissatisfaction as well as distress the patient, the partner or both.
Historically attributed to psychological causes, new theories suggest that premature ejaculation may have an underlying neurobiological cause which may lead to rapid ejaculation.
