Background: Premature ejaculation (PE) is a common concern for men and their partners, but current diagnostic tools mainly focus on men who have vaginal intercourse. The Masturbation Premature Ejaculation Diagnostic Tool (MPEDT) was created to address this gap, but its effectiveness for men who only engage in self-masturbation has not been studied. This research aimed to determine the frequency of self-reported PE patients who do not have vaginal intercourse and to evaluate the diagnostic accuracy of MPEDT for this group.
Method: The study involved 446 male patients aged 18 to 40, and 40 non-self-reported-PE and non-vaginal-intercourse healthy males. Participants completed the MPEDT questionnaire and reported their recent six-months sex frequency.
Result: Among the patients seeking treatment for PE, 21.75% had not engaged in vaginal intercourse in the past six months. Of the PE patients who completed the MPEDT questionnaire (86 patients), 90.7% were diagnosed with masturbatory-PE (MPE). The sensitivity for self-reported MPE and specificity for self-reported non-MPE were 93.02% and 72.5%, respectively.
Discussion: For patients who have not had vaginal intercourse in the past six months but engage in masturbation and seek treatment for PE, the PEDT may not effectively assess their ejaculatory function. The MPEDT, however, can effectively evaluate their ejaculatory function. This study also emphasizes the need for diagnostic tools tailored to this population.
