Objective(s); The aim of this study was to determine the efficacy of a new Cognitive Behavioral Treatment (CBT) for the Premature Ejaculation (PE) called Sphincter Control Training (SCT) in a variation of the classical stop-start technique first introduced by Semans in 1956 and the possible benefit of using a masturbation aid device for the treatment.

Material and Method(s); The present study included 35 patients’ ≥18 years that met diagnostic criteria for PE including intravaginal ejaculatory latency time (IELT) of ≤2 minutes and had a Premature Ejaculation Diagnostic Tool (PEDT) score ≥11. Subjects were randomized to a one experimental group that used the device with 7 weeks exercise programme (n=18) a second experimental group that only used the exercise programme (n=17). There was one outlier subject identified by Cook's distance. As a main outcome measure used the fold increase of the IELT, it was calculated by the geometric mean IELT value after treatment divided by the geometric mean IELT value at the start of treatment by stopwatch-measured.

Result(s); The fold increase of the IELT was 2.7 in experimental group number one (exercise and device), and in experimental group number two (exercise) was 1.3 at endpoint.

Conclusion(s); Results provide support for the efficacy of this novel cognitive behavioral therapy. The combination of device and exercise programme appears to be better than only exercise and could be a promising first line treatment for patients with PE, which has clear advantages over other available treatment options. Much more research is necessary to determine if CBT intervention could be a real alternative to pharmaceutical PE treatment.
