AbstractBackgroundWhether conventional behavioral therapies for premature ejaculation can significantly improve the intravaginal ejaculatory latency time is still controversial. Prone masturbation is rare and observed in some patients with delayed ejaculation. Therefore, we tried to verify whether the regular prone masturbation training method had a therapeutic effect on premature ejaculation.MethodsFrom July to December 2018, a total of 21 patients met the enrollment criteria and volunteered to participate. Participants were diagnosed with premature ejaculation with an intravaginal ejaculatory latency time of less than 3 min and a Premature Ejaculation Diagnostic Tool score greater than 9. Participants performed 12‐week prone masturbation training.ResultsTen patients completed the entire treatment regimen. The mean age of the 10 participants was 30.4 ± 6.1 years, the mean frequency of sexual intercourse was 1.9 ± 0.83 times a week, and the median duration of premature ejaculation was 1.5 years. After 3 months of prone masturbation training, the median self‐reported intravaginal ejaculatory latency time significantly increased from 60 to 105 s (p = 0.011), and the mean Premature Ejaculation Diagnostic Tool scores decreased from 15.0 ± 3.7 to 12.7 ± 3.7 points (p = 0.119).ConclusionsThe regular prone masturbation training method, as a novel behavioral therapy, probably has a therapeutic effect on premature ejaculation.
