Oral paroxetine for premature ejaculation: a randomized controlled study / 中华男科学杂志

<p><b>OBJECTIVE</b>To validate the therapeutic efficacy of paroxetine in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>Eighty PE patients up to the inclusion criteria were equally randomized to an experimental and a control group. We observed all the patients for 4 weeks and recorded the baseline data on intravaginal ejaculatory latency time (IELT) and sexual satisfaction scores, followed by oral medication of paroxetine at 20 mg/d for the patients in the experimental group and placebo for the controls. Thirty days after the treatment, we again recorded IELT and sexual satisfaction scores of the patients.</p><p><b>RESULTS</b>After the treatment, the experimental group showed significantly prolonged IELT ([5.75 +/- 1.24] min) and increased sexual satisfaction score (6.4 +/- 1.2) as compared with the baseline data ([0.89 +/- 0.21] min and [2.7 +/- 0.9]) (P < 0.01). The control group exhibited no significant differences before and after the medication either in the mean IELT or in sexual satisfaction scores ([1.06 +/- 0.28] min vs [0.97 +/- 0.18] min and 3.6 +/- 1.3 vs 3.1 +/- 1.1, P > 0.05).</p><p><b>CONCLUSION</b>Oral medication of paroxetine at 20 mg/d for 30 days could improve IELT and sexual satisfaction in PE patients.</p>

Ultrasonographic changes in the epididymis after long-term vasectomy / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the ultrasonographic changes in the epididymis after long-term vasectomy.</p><p><b>METHODS</b>Sixty-four patients with a history of vasectomy for more than 10 years (vasectomy group) and another 60 without vasectomy (control group) were included in the study. The patients were referred to scrotal ultrasonography for epididymal indications. The shape, thickness and internal echoes of the head, body and tail of the epididymis were observed with high frequency ultrasonography (HFU), and the blood flow changes were observed with color Doppler flow imaging (CDFI) or color Doppler power imaging (CDPI).</p><p><b>RESULTS</b>Significantly higher rates were found in the vasectomy group than in the control: thickened body (64.1% vs 15.0%) and tail (78.1% vs 51.7%) of the epididymis, thickened head, body and tail (42.2% vs 8.3%) of the epididymis, and epididymal tubular ectasia (54.7% vs 8.3%). However, increased blood flow in the epididymis was seen at a significantly lower rate in the vasectomy group than in the control (15.6% vs 61.7%).</p><p><b>CONCLUSION</b>The ultrasonographic changes in the epididymis after long-term vasectomy were mainly epididymis thickening and epididymal tubular ectasia, mostly with no or diminished blood flow in the epididymis.</p>
