Delayed ejaculation (DE) diagnosis can be improved by considering both ejaculation latency (EL) time and ejaculatory control. These factors help distinguish men with DE from those without, informing clinical practice.
Area of Science:
- Sexual medicine
- Urology
- Psychology
Background:
- Current delayed ejaculation (DE) criteria include long ejaculation latency (EL), lack of ejaculatory control, and associated distress.
- Few studies have examined these criteria in men desiring quicker ejaculation during partnered sex.
Purpose of the Study:
- To standardize DE criteria by understanding characteristics of men who wish to ejaculate sooner.
- To analyze their EL, ejaculatory control, bother/distress, and perceptions of typical/ideal ELs and those associated with premature ejaculation (PE).
Main Methods:
- 572 men completed an online survey on their EL, perceived control, bother/distress, and general/PE EL perceptions.
- Four groups were formed: probable DE (with/without control issues), a reference group (no ejaculatory disorders), and men with PE.
Main Results:
- Men with probable DE had ELs twice as long as the reference group.
- DE men with control issues (DE2) showed greater differences compared to the reference group in EL and ejaculatory control, but not bother/distress.
- Both DE and reference groups differed significantly from the PE group.
Conclusions:
- Ejaculation latency (EL) and ejaculatory control are key differentiators for diagnosing delayed ejaculation (DE).
- Bother/distress levels did not significantly differentiate DE from controls.
- Findings support empirically based standardization for DE diagnosis.
