Background:
Acupuncture therapy has been used by many researchers in both male and female sexual dysfunction studies.
Objective:
To determine whether acupuncture is effective as a premature ejaculation (PE) treatment compared with paroxetine and placebo.
Design, Setting, And Participants:
The study was conducted with methodologic rigor based on Consolidated Standards of Reporting Trials (CONSORT) criteria. Ninety patients referred to the urology clinic at a tertiary training and research hospital with PE were included in this randomized controlled trial and randomly assigned into paroxetine, acupuncture, and placebo groups. Heterosexual, sexually active men aged between 28 and 50 yr were included. Men with other sexual disorders, including erectile dysfunction; with chronic psychiatric or systemic diseases; with alcohol or substance abuse; or who used any medications were excluded.
Intervention:
The medicated group received paroxetine 20 mg/d; the acupuncture or sham-acupuncture (placebo) groups were treated twice a week for 4 wk.
Measurements:
Intravaginal ejaculation latency times (IELTs) and the Premature Ejaculation Diagnostic Tool (PEDT) were used to assess PE. IELTs were calculated by using a partner-held stopwatch. Data were analyzed statistically.
Results And Limitations:
Median PEDT scores of paroxetine, acupuncture, and placebo groups were 17.0, 16.0, and 15.5 before treatment, and 10.5, 11.0, and 16.0 after treatment, respectively (p=0.001, p=0.001, and p=0.314, respectively). Subscores after treatment were significantly lower than subscores before treatment in the paroxetine and acupuncture groups but remained the same in the placebo group. Significant differences were found between mean-rank IELTs of the paroxetine and placebo groups (p=0.001) and the acupuncture and placebo groups (p=0.001) after treatment. Increases of IELTs with paroxetine, acupuncture, and placebo acupuncture were 82.7, 65.7, and 33.1 s, respectively. Extent of ejaculation delay induced by paroxetine was significantly higher than that of acupuncture (p=0.001). The most important limitation of the study was the lack of follow-up.
Conclusions:
Although less effective than daily paroxetine, acupuncture had a significant stronger ejaculation-delaying effect than placebo.
