Abstract

INTRODUCTION:

Current evidence suggests that Cognitive Behavioral therapy (CBT) has a limited role in the contemporary management of premature ejaculation (PE).

AIM:

The aim of this study was to determine the efficacy of a new CBT for the PE called Sphincter Control Training (SCT) in combination with a masturbation aid device.

METHODS:

The present study included 35 patients' 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. Participants completed all phases of a randomized controlled clinical study with a parallel group design, which was approved by the Ethical Committee of the Hospital Morales Meseguer of Murcia (Spain).The two treatment groups completed SCT over 7 weeks. The SCT consists of four different exercises and an educational session. Its objective is to provide patients with greater knowledge, awareness, and control of the external urethral sphincter. The only difference between groups was the use of a masturbation aid device called Flip Zero (TFZ-001) from the Japanese company Tenga Co., Ltd.

OUTCOMES:

The main measure was the "fold increase" (FI) of the IELT, which was calculated using the geometric mean pre-treatment and post-treatment. In addition, Premature Ejaculation Profile PE was used as a secondary measure.

RESULTS:

The geometric mean of the measurements corresponding to the 7 weeks of treatment was calculated, and both groups were compared by means of an ANCOVA test, finding a statistically significant difference (F: 10.51, 1; p = .003) in the increase experienced by subjects in the group with the device (GWD) mean = 166.63, SD = 106.54) compared with that experienced by subjects in the group without device (GWtD) (mean = 86.99, SD = 59.98).Using Student's t-test, the Fold increase (FI) corresponding to both groups were compared. The results showed statistically significant differences (p = .008) between the measurements corresponding to the GWtD (1.38 (0.50)) and those relative to the GWD (2.69 (1.81)).

CLINICAL IMPLICATIONS:

The FI in the GWD at the end of the trial allow us to consider this new CBT as a potential and viable PE treatment alternative. No side effects were observed in either treatment group and it required little therapeutic input and no partner involvement.

STRENGTHS & LIMITATIONS:

The main limitation of this study is the lack of a 3- to 6-month follow-up of the treatment and placebo control.

CONCLUSIONS:

This SCT exercise program combined with the use of a masturbation device shows promise because has numerous advantages in relation to current recommended treatments in patients with PE.
