The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation has agreed on an evidence-based, unified definition that describes both the acquired and lifelong forms of premature ejaculation (PE).
In 2007, the committee conducted a literature review and developed the first evidence-based definition for lifelong PE. However, they felt that there was not enough published data to form a definition of acquired PE.
The committee met in April 2013 and again reviewed the scientific literature on PE. At this time, committee members unanimously agreed that lifelong and acquired PE had certain factors in common, including short ejaculatory latency, reduced or absent ejaculatory control, and negative personal consequences.
They found that men with acquired PE tend to be older and are more likely to have erectile dysfunction (ED). Older men also tend to have higher rates of comorbidities, cardiovascular risk factors, and a longer intravaginal ejaculation latency time (IELT).
The committee agreed that an IELT of 3 minutes – either estimated by the patient or measured with a stopwatch – would be the cutoff point for diagnosing acquired PE.
Their unified definition of both acquired and lifelong PE is “a male sexual dysfunction characterized by
- ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration from the first sexual experiences (lifelong PE), or, a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE), and
- the inability to delay ejaculation on all or nearly all vaginal penetrations, and
- negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy.”
