Operational Definition of Premature Ejaculation

For evidence-based research, it is of utmost importance to have a definition of premature ejaculation. However, because of conflicting ideas about the essence of premature ejaculation, sexologists have never reached an agreement on a definition.

DSM-IV (47) defines premature ejaculation as "persistent or recurrent ejaculation with minimal sexual stimulation before, upon, or shortly after penetration and before the person wishes it." Until recently, any scientific basis for the DSM-IV definition was lacking. For instance, the meaning of "persistent," "recurrent," "minimal," and "shortly after" is vague and certainly needs further qualification. In order to get an empirically operationalized definition, Waldinger and co-workers investigated 110 consecutively enrolled men with lifelong premature ejaculation (48). In this study, men and their female partners were instructed to use a stopwatch at home during each coitus for a period of 4 weeks (Fig. 9.2). It was found that 10% of these men ejaculated between 1 and 2 min but that the majority (90%) of them ejaculated within 1 min of intromission, and even 80% actually ejaculating within 30 s whereas 60% ejaculated within 15 s (48). The age of the men and duration of their relationship were not correlated with the ejaculation time. On the basis of this study, Waldinger and co-workers empirically defined lifelong premature ejaculation as an ejaculation that is <1 min in >90% of episodes of sexual intercourse, independent of age and duration of relationship (48). It has to be noted that this definition defines premature ejaculation as being an early ejaculation that is independent of psychological or relationship distress. Thus, assessment by stopwatch revealed that premature ejaculation is a matter of seconds and not of minutes. In this respect, the ICD-10 definition (e.g., ejaculation before or within 15 s) seems more appropriate than the DSM-IV definition, but both need to be adapted to these recent data.
