What is Premature Ejaculation (PE)?
Premature ejaculation is defined as ejaculation that occurs sooner than desired, either before or shortly after penetration, causing distress to one or both partners. It's one of the most common male sexual dysfunctions, affecting approximately 30% of men at some point in their lives.
Types of PE:
- Lifelong (Primary) PE: Present since first sexual experiences, usually genetic/neurobiological
- Acquired (Secondary) PE: Develops after period of normal function, may be related to medical/psychological factors
- Variable PE: Inconsistent, occurs in some situations but not others
- Subjective PE: Perception of early ejaculation despite normal time (psychological)
Diagnostic Criteria:
According to the International Society for Sexual Medicine (ISSM):
- Ejaculation within ~1 minute of vaginal penetration (for lifelong PE)
- Inability to delay ejaculation on all or nearly all penetrations
- Negative consequences (distress, frustration, avoidance of intimacy)
