The study was done to help standardize criteria for DE by better understanding characteristics of men who desire to ejaculate sooner during partnered sex in terms of their EL, reported ejaculatory control, and level of bother/distress, as well as their perceptions of typical and ideal ELs for men in general and of ELs for men with premature ejaculation or PE.
572 men in total were recruited through social media and responded to an online survey as a module for the purpose of data collection for the study. ELs for men with probable DE were twice as long as those with no ejaculatory disorders. When probable DE men were further subdivided into DE2 and DE1, differences were greater for the DE2 group. DE2 men also differed significantly from the reference group on ejaculatory control/advancement but not on bother/distress.
The study concluded that both EL and ejaculatory control differentiate men with probable DE from a control reference group having no ejaculatory disorders. Differences in the experienced distress did not emerge as significant. Implications for diagnosing men with DE are presented.
