Effects of Transcranial Direct Current Stimulation on the Treatment of Premature Ejaculation in Men with Sexual Dysfunction

Abstract

Background: Premature ejaculation (PE) is a common sexual dysfunction in men, affecting various aspects of life, including mental and emotional health and interpersonal relationships with spouses. Objectives: The present study aimed to investigate the effects of transcranial direct current stimulation (tDCS) on the treatment of PE in men with sexual dysfunction. Methods: This was a quasi-experimental study with a pretest-posttest control design and a two-month follow-up. The statistical population included all men with PE living in Tehran, Iran, in 2021. A total of 30 people within the 25 - 66 age group were selected and placed in the experimental and control groups. The experimental group underwent tDCS for one month (8 sessions), and the control group received no intervention. The research instrument included the international index of erectile function (IIEF). The data were analyzed using descriptive and inferential statistics (ANCOVA) with SPSS. Results: The experimental and control groups had a significant difference in the components of PE, including orgasmic function and overall satisfaction (P < 0.001). The results suggested that tDCS improved orgasmic function and overall satisfaction in men with sexual dysfunction. Furthermore, this method remained effective for two months. Conclusions: The tDCS method was influential in improving PE. Considering the effectiveness of tDCS in treating PE and increasing sexual satisfaction, it is recommended to use this method to treat this disorder.
