Clinical efficacy of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation for premature ejaculation / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>Totally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.</p><p><b>RESULTS</b>One patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).</p><p><b>CONCLUSION</b>Oral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.</p>

Cigarette smoke affects sexual function of male rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the effect of cigarette smoke on the sexual function of male rats.</p><p><b>METHODS</b>Based on Ozyurt's smoking model, we equally divided 30 male adult Sprague-Dawley rats into a control and a smoking group, and exposed the latter to cigarette smoke for 60 days. A week before the end of the experiment, we added 5 female rats to each group and observed their mating through 24-hour video surveillance. Sixty days later, all the rats were killed for the determination of the level of testosterone (T) in the plasma and the activity of nitric oxide synthase (NOS) in the corpus cavernosum, and Masson-dyeing image analysis of the penile tissue.</p><p><b>RESULTS</b>Compared with the controls, the rats in the smoking group showed a significant reduction in the times of mating, the level of plasma T (P < 0.05) and the activity of NOS in the penile cavernous tissue (P < 0.05), but a slight increase in the collagen fibers and obvious changes in the blood sinuses.</p><p><b>CONCLUSION</b>Cigarette smoke seriously affected penile erection in the experimental rats. The decrease in plasma T, NOS activity and the area of smooth muscle may be an important mechanism underlying their erectile dysfunction.</p>

Etiology analysis of male pseudohermaphroditism / 中华泌尿外科杂志

Objective To discuss the etiology of male pseudohermaphroditism. Methods The clinical data of 42 male pseudohermaphroditisms were retrospectively analyzed.Among the 42 cases (mean age of 10 years,range from 8 to 19 years),39 caseg social gender were female sex and 3 were male.Physical examination indicated abnormal external genitalia,cryptorchidism,hypospadias and mass of pelvis or inguinal.Chromosome examination showed that 39 cases were 46,XY,2 cases of 45,X/46.XY and 1 case of 45,X/47,XXY.Etiology analyses were established in 42 cases by eytogeneties,endocrinology,B-ultrasound or CT examination,celiac exploration and pathology examination.Results All the 42 cases received operation.All cases were treated by hormone replacement according to the social gender which they selected.Thirty-three cases were followed up for 7 to 10 years. Conclmion The etiology of male pseudohermaphroditism includes anti-androgen syndrome,testosterone synthetase deficiency,resistant LH/hCG by testis,simple gonadal dysgenesis,mixed gonadal dysgenesis and resistant mullerian duct syndrome.
