Abstract

Evidence-based definitions improve clinical practice and research. Nonetheless, the International Society of Sexual Medicine (ISSM) and the American Psychiatric Association's (DSM-5) definitions regarding lifelong and acquired premature ejaculation (PE) and delayed ejaculation (DE) require reexamination. Existing Intravaginal Ejaculation Latency Time (IELT) evidence, the ISSM position papers, and articles both supporting and critiquing the ISSM's definitions were reviewed. Disproportionately, the findings from those studies document that the majority of men's IELT range is approximately 4 to 10 minutes. Such robust quantitative evidence should become the basis for determining the temporal criterion when defining both PE and DE. Any bilateral deviation from that majority's ∼4- to 10-minute IELT range should meet the qualification for the temporal diagnostic criterion. However, for a man to be diagnosed with a disorder, a licensed health-care clinician (HCC) must also determine that the man suffers from "lack of control" and "distress." Diagnosis would include subtyping Lifelong or Acquired, Global or Situational, similar to the ISSM guidelines and specifying mild, moderate, or severe-similar to DSM-5 requirements. "Control" and "distress" should trump latency and convey greater weight in the diagnostic process. Loosened latency criteria could result in false positive diagnoses; however, requiring a licensed HCC to evaluate control and distress reduces that risk.
