title: Premature ejaculation. 2. Classification and diagnosis.
abstract: A classification of premature ejaculation must distinguish between hyper-orgasmic or hypo-orgasmic, between situational or global; furthermore, it must define whether it occurs during vaginal penetration only or also in masturbation, and must study its latency periods and its relationships to the erectile dysfunction, with which it is often associated. Tests with local anesthetics, biothesiometry and penile vibrotactile stimulation, integrated with a thorough study of the general and psycho-sexual history, provide a good diagnostic classification that makes the therapeutic approach appropriate.
