OBJECTIVETo investigate the correlation of sexual dysfunction with psychological abnormalities by analyzing the sexual function and mental state of the patients with redundant prepuce or phimosis.

METHODSThis study included 216 randomly selected patients with redundant prepuce or phimosis and 85 normal male controls. We conducted investigations among the subjects using a questionnaire on the general data of the patients, Chinese Index of Sexual Function for Premature Ejaculation (CIPE), International Index of Erectile Function (IIEF), and Symptom Checklist 90 (SCL-90). Then we assessed the status of premature ejaculation (PE) and erectile dysfunction (ED), calculated the incidence of psychological abnormalities, such as depression and anxiety, and analyzed the correlation of PE and ED with the mental state of the patients.

RESULTSThe PE and ED patients scored significantly higher than normal controls on SCL-90, somatization, compulsion, depression, anxiety and other factors (P < 0.05). CIPE scores were correlated with the scores on SCL-90, somatization, compulsion, interpersonal sensitivity, depression, anxiety and other factors, while ED-related scores showed no correlation with the scores on SCL-90 and other factors.

CONCLUSIONPatients with redundant prepuce or phimosis have poor mental health, and there is an interaction between PE and the mental state of the patient.

OBJECTIVETo observe the clinical effects of needle-pricking therapy, a newly medical and minimally invasive technique, for functional retrograde ejaculation and to explore its mechanism. Methods Thirty-six patients with functional retrograde ejaculation were randomly divided into an observation group(19 cases) and a control group(17 cases) In the observation group,needle-pricking therapy was used at Guanyuan(CV 4) and bilateral sacral plexus nerve,lumbar 1 nerve and greater occipital nerve stimulating points,once a week. In the control group, midodrine tablets were prescribed orally,three times a day. All the treatment was given for 9 weeks. The clinical effects of the two groups were observed, and the levels of luteinizing hormone(LH), testosterone(Tes) and estra4 diol(E2) were compared between the two groups.

RESULTSThe total effective rate of the observation group was, 89. 47%(17/19), which was better than 47.06% (8/17) of the control group(P<0. 05). The LH and Tes were obviously increased and E2 was decreased compared with those before treatment in the observation group(all P< 0. 01). Tes was raised(P<0. 05) and E2 was apparently declined in the control group(P<0. 01). After treatment, the differences of serum LH and Tes were statistically significant between the two groups(both P<0. 01).

CONCLUSIONNeedle-pricking therapy has advantages for functional retrograde ejaculation probably in that stimulating lumbosacral nerves can strengthen the function of pelvic floor muscles and urethral expansion muscle and regulate sexual gland axis.

OBJECTIVETo investigate the prevalence of male sexual dysfunction in males with Parkinson's disease and the pathogenesis and related factors of the problem.

METHODSWe evaluated the sexual function of 140 men with Parkinson's disease using Mini-mental State Examination (MMSE), Unified Parkinson's Disease Rating Scale (Part III) (UPDRS III), Hoenhn-Yahr Staging (HYS), Hamilton Depression Scale (HAMD) and Sexual Dysfunction Standard of ICD-10. We calculated the Levodopa equivalent doses (LED) for all the patients.

RESULTSSexual dysfunction was found in 58 (41.43%) of the patients with Parkinson's disease. There were no significant differences in age, education, age of onset, course of disease and scores on UPDRS III, HYS and LED between the sexual dysfunction and normal sexual function groups. The HAMD score was 14.95 +/- 9.12 in the sexual dysfunction group, significantly higher than 10.96 +/- 9.82 in the normal sexual function group (P < 0.05), and it was positively correlated with the inci- dence of male sexual dysfunction (P < 0.05).

CONCLUSIONSexual dysfunction is a common symptom in males with Parkinson's disease, and is correlated with the high HAMD score of Parkinson's disease patients.

Animal models in sexual dysfunction were reviewed to further improve the modeling methods and to promote the effectiveness of drug evaluation translation from animal models to humans. A MEDLINE search was performed to retrieve articles relating to animal models in sexual dysfunction. Researches on a variety of animal models in sexual dysfunction, with their own merits, has to a certain extent contributed to the understanding of sexual function. However, no models could give a fully accurate assessment of sexual function. The existing sexual function studies on animal models of interpretive function, the development mechanisms, the effects of drugs on sexual function and the clinical translation still have some deficiencies, but with their basic principles and ideas for the improvement of the models and the preservation of the valuable data of drugs and clinical trials.

OBJECTIVETo investigate the influence of chronic prostatitis on premature ejaculation (PE) and erectile dysfunction (ED) and the correlation of chronic prostatitis with PE and ED.

METHODSWe adopted NIH-CPSI, CISFPE and IIEF-5, interviewed 623 patients with chronic prostatitis, and recorded their scores on the above systems.

RESULTSThe incidence of PE was 39.0% and the rates of the mild, moderate and severe types were 26.2%, 12.0% and 0.8%, respectively. It developed mostly among the younger patients, accounting for 42.9% (103/240), 37.0% (95/257) and 35.7% (45/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. The incidence of ED was 16.9% and the rates of the mild, moderate and severe types were 14.9%, 1.0% and 1.0%, respectively. It occurred mostly among the older patients, accounting for 13.8% (33/240), 11.3% (29/257) and 34.1% (43/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. Analyses revealed no significant correlation among the scores on NIH-CPSI, CISFPE and IIEF-5.

CONCLUSIONThere is a high incidence of PE and ED among patients with chronic prostatitis, but without significant correlation between the severity of chronic prostatitis and that of PE and ED.

We evaluated the genotypes of the serotonin transporter gene (5-HTT) in patients with premature ejaculation (PE) to determine the role of genetic factors in the etiopathogenesis of PE and possibly to identify the patient subgroups. A total of 70 PE patients and 70 controls were included in this study. All men were heterosexual, had no other disorders and were either married or in a stable relationship. PE was defined as ejaculation that occurred within 1 min of vaginal intromission. Genomic DNA from patients and controls was analyzed using polymerase chain reaction, and allelic variations of the promoter region of the serotonin transporter gene (5-HTTLPR) were determined. The 5-HTTLPR (serotonin transporter promoter gene) genotypes in PE patients vs. controls were distributed as follows: L/L 16% vs. 17%, L/S 30% vs. 53% and S/S 54% vs. 28%. We examined the haplotype analysis for three polymorphisms of the 5-HTTLPR gene: LL, LS and SS. The appropriateness of the allele frequencies in the 5-HTTLPR gene was analyzed by the Hardy-Weinberg equilibrium using the chi2-test. The short (S) allele of the 5-HTTLPR gene was significantly more frequent in PE patients than in controls (P<0.05). We suggest that the 5-HTTLPR gene plays a role in the pathophysiology of all primary PE cases. Further studies are needed to evaluate the relationship between 5-HTTLPR gene polymorphism and patient subgroup (such as primary and secondary PE) responses to selective serotonin reuptake inhibitors as well as ethnic differences.

OBJECTIVETo observe the effect of Uighur medicine gu-jing-mai-si-ha tablet (GJMSHT) for treatment of premature ejaculation (PE) and to explore part of its mechanism.

METHODSThe condition of patients was scored by related questionnaire, and the intravaginal ejaculation latency time (IELT) was observed before and after GJMSHT treatment, with the blood levels of nitric oxide (NO) and prostaglandin F2alpha (PGF2alpha) detected in PE patients as well. The results were compared with those in the control group.

RESULTSAfter treatment, the scores of PE and IELT, as well as the levels of NO and PGF2alpha, all increased significantly compared to those before treatment in the treated group (P<0.01), while in the control group, all the parameters were insignificantly changed (P>0.05). Therefore, the difference of these parameters between the two groups after treatment all showed statistical significance (P<0.01).

CONCLUSIONGJMSHT could treat PE effectively, its mechanism is possibly by strengthening the coordination of the related smooth muscles through increasing the blood levels of NO and PGF2alpha, and the endurance of patients to the cavitary effect of prostatico-urethral pressure, thus postponing the arrival of urgent ejaculatory feeling.
