Preliminary study of electric stimulation on premature ejaculation in patients with chronic pelvic pain syndrome or chronic prostatitis

Purpose: To investigate the clinical efficacy of electric stimulation on the treatment of premature ejaculation (PE) in patients with chronic pelvic pain syndrome (CPPS) or chronic prostatitis (CP). Material and methods: Fourteen patients who complained with voiding syndromes, defecation disorder, pelvic pain and sexual problems were included in this prospective study. The white blood cells in prostatic expressed secretion of these patients were less than 10 per high-power field. In addition to the therapy of alpha-blocker, muscle relaxant and anti-cholinergics, six weekly cessions of electric stimulation were given on lithotomy position for specific group of patients. These patients whose PE scale scored as 4 or greater and the intra-vaginal ejaculation latency time (IVELT) as 2 or greater were noted. PE was graded on a scale of 0 to 8 (0 = almost never, 8 = almost always). The IVELT was graded on a scale of 0 to 3 (0 = longer than 5 min, 3 = shorter than 1 min). These scales were graded before the initiation and 6 weeks after the treatment. Results: The mean age of 14 patients was 44 years old. The mean pre-treatment PE and IVELT scale was 5.78 ± 0.14 and 2.78 ± 0.18, respectively. The PE and IVELT scale after electric stimulation treatment was 4.0 ± 0.60 (P = 0.026) and 1.5 ± 0.35 (P = 0.006). Seven patients (50%) reported the improvement of PE after electric stimulation. The PE and IVELT scale after treatment was 2.2 ± 0.60 (P = 0.0022) and 0.14 ± 0.35 (P < 0.0001), respectively. Seven patients (50%) remained unchanged after treatment. The PE and IVELT scale after treatment was 5.71 ± 0.12 (P = 0.86) and 2.80 ± 0.38 (P = 0.55). Conclusion: Electric stimulation seems to have a benefit on improving PE in patients with CPPS/CP in our preliminary prospective study. Electric stimulation may be an important and encouraging part of the treatment modalities in PE.
