There has been increasing interest in the psycho-socio-relational and sexual disorders of infertility, as the risk of psychological burden among infertile men with sexual dysfunctions is significant. The purpose of this study was to develop and to validate a predictive model to estimate individual psychological burden among infertile men with sexual dysfunction and study the association between them. Comprehensive data were collected for infertile men (n = 480) who sought treatment for infertility in a reproductive medicine center between June 2012 and December 2013. Using independent predictors of psychological burden from the least absolute shrinkage and selection operator, univariable and multivariable analyses were developed into two models. Predictive accuracy was compared between the models. We explored the association between sexual dysfunction and psychological burden. A total of 480 patients were analyzed using 10-fold cross-validation. Independent predictors of psychological burden were incorporated into a model to measure anxiety (corrected-area under curve (AUC): 77.3%) and a model to measure depression (corrected-AUC: 70.2%). Anxiety and depression were both associated with erectile dysfunction (P < 0.05), with anxiety demonstrating the strongest association. Only anxiety was associated with premature ejaculation (P < 0.05). Premature ejaculation was not found to be associated with depression (P > 0.05). Predictive models for psychological burden among infertile men with sexual dysfunction are presented, and we found that there is an association between psychological burden and sexual dysfunction. According to the models, proper counseling and treatment of sexual dysfunction in infertile men may reduce the psychological burden, help attain natural pregnancy, and improve the quality of life.

ObjectiveTo study the clinical application value of the penile erectile strength measurement (PESM) band in the differentiation of psychogenic from organic erectile dysfunction (ED).

METHODSEighty ED patients unable to achieve or maintain adequate penile erection to complete sexual intercourse were included in the experimental group and another 40 healthy subjects with normal erectile function enrolled as controls. The ED cases were classified into mild, moderate and severe ED according to the IIEF-5 scores and divided into psychogenic and organic ED based on the results of the nocturnal penile tumescence (NPT) test. Then all the subjects underwent a three-night continuous monitoring with the PESM band and, according to the band fracture rate, the ED cases were also classified into psychogenic and organic ED. The rates of missed diagnosis, misdiagnosis and diagnostic coincidence of PESM were calculated with the results of NPT as the standard for differentiating psychogenic from organic ED.

RESULTSThe results of NPT tests revealed 51 cases of psychogenic and 29 cases of organic ED in the experimental group. The band fracture rate in PESM was 95.0% in the mild, 80.9% in the moderate and 52.8% in the severe ED patients. Of the 51 cases of psychogenic ED detected by NPT test, 43 were diagnosed as psychogenic and the other 8 as organic ED with the PESM band, with a coincidence rate of 84.3%. Of the 29 cases of organic ED revealed by NPT test, 5 were diagnosed as psychogenic and the other 24 as organic ED by PESM, with a coincidence rate of 82.8%. Normal erectile function with three-level fracture of the band was observed in the PESM of the normal controls, which showed a coincidence rate of 100% with the results of NPT tests. Based on the standard of the NPT test, the rates of missed diagnosis, misdiagnosis and diagnostic coincidence of the PESM band in differentiating psychogenic from organic ED were 15.7%, 17.2%, and 83.8%, respectively, with a Kappa value of 0.656 (P <0.05).

CONCLUSIONSThe penile erectile strength measurement band can be used as a screening tool for initial differentiation of psychogenic from organic ED.

BACKGROUNDSexual health positively correlates with overall wellbeing. Existing therapeutics to enhance male sexual health are limited by factors that include responsiveness, adherence and adverse effects. As the population ages, safe and effective interventions that preserve male sexual function are needed. Published research suggests that various preparations of Kaempferia parviflora, a plant in the Zingiberaceae (ginger) family, support cardiovascular health and may ameliorate erectile function.

OBJECTIVEThe aim of this study was to examine the effects of KaempMax™, an ethanol extract of the K. parviflora rhizome, on erectile function in healthy middle-aged and older men.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONSWe conducted an open-label, one-arm study on 14 generally healthy males aged 50-68 years with self-reported mild erectile dysfunction, who were not using prescription treatments. Participants took 100 mg KaempMax™ daily for 30 days.

MAIN OUTCOME MEASURESEvaluations were conducted at baseline and on the final study assessment. Primary efficacy analyses included the International Index of Erectile Function (IIEF); secondary efficacy analyses included the Global Assessment Question about erectile function.

RESULTSThirteen participants completed the 30-day study. Supplementation with KaempMax™ resulted in statistically significant improvements in erectile function, intercourse satisfaction and total scores on the IIEF questionnaire. KaempMax™ was well tolerated and exhibited an excellent safety profile.

CONCLUSIONOur results suggest that KaempMax™ may improve erectile function in healthy middle-aged and older men. While the effects were not as pronounced as what might be seen with prescription medication, most participants found them satisfactory. Additional, longer and placebo-controlled clinical trials will be needed.

Objective: To evaluate the effects of three different medications with tadalafil on erectile dysfunction (ED) in young men with primary sexual failure. METHODS: This study included 76 male ED patients aged 21－35 years who had primary sexual failure but normal nocturnal penile tumescence and rigidity and failed to respond to psychotherapy. We randomly assigned them to receive oral tadalafil once daily, on demand, or once-daily + on-demand. After 2－3 months of treatment, we evaluated the effects based on the scores of the patients in the five domains of the International Index of Erectile Function (IIEF-5). RESULTS: After medication, all the patients showed significantly increased scores in the four domains of IIEF-5, namely, erectile function, orgasmic function, intercourse satisfaction, and overall satisfaction. The on-demand group achieved even higher scores in erectile and orgasmic functions but a lower score in sexual desire than the once-daily group. However, the patients in the once-daily + on-demand group exhibited more significant improvement than those in the other two in all the five domains. CONCLUSIONS Once-daily + on-demand medication with tadalafil can significantly enhance the therapeutic effect on psychogenic ED in young men with primary sexual failure.

Objective: To explore the topological properties of the degree and strength of nodes in the binary and weighted brain white matter networks of the patients with psychogenic erectile dysfunction (pED) and analyze the changes of myelin integrity, number and length of the white matter fibers in the topological space. METHODS: Diffusion tensor imaging data were obtained from 21 patients with pED and 24 healthy controls matched in sex, age, and years of education and subjected to preprocessing. The whole cerebral cortex was divided into 90 regions, followed by fiber tracking, construction of the binary and weighted white matter networks, and calculation of the node degrees and connectivity strengths in different brain regions. The property values were compared between the two groups using the two-sample t-test, the results were corrected by multiple testing correction, and the correlation of the property values with the erectile function of the patients was subjected to Pearson's correlation analysis. RESULTS: Compared with the healthy controls, the pED patients showed significantly decreased node degree of the left triangular part of inferior frontal gyrus (IFG) (7.54±1.44 vs 5.95±1.28, t = －3.88, corrected P = 0.02), medial orbital part of superior frontal gyrus (SFG) (10.08±3.60 vs 6.29±3.30, t = －3.67, corrected P = 0.02), and amygdala (6.50±2.11 vs 4.29±1.31, t = －4.16, corrected P = 0.01) in the binary networks, as well as the connectivity strength of the left triangular part of IFG (2.50±0.68 vs 1.72±0.50, t = －4.35, corrected P = 0.01), medial orbital part of SFG (3.17±0.97 vs 2.08±1.10, t = －3.53, corrected P = 0.03), and amygdala (1.80±0.69 vs 1.11±0.39, t = －4.03, corrected P = 0.01) in the fractional anisotropy (FA) weighted networks. The node degree of the left amygdala was negatively correlated with the total score (r = －0.47,P = 0.04), second item score (r = －0.46, P = 0.03), and third item score of IIEF-5 (r = －0.45, P = 0.04) in the pED patients. CONCLUSIONS The myelin integrity of the white matter fibers in the left frontal lobe and amygdale is impaired in pED patients, which leads to the aberrant generation, processing and regulation of their emotions. The decreased pivotal role and importance of the white matter fibers connecting the left amygdale may be associated with pED.

Objective: To investigate the relationship of erectile dysfunction (ED) with psychological factors in male patients with infertility. METHODS: We conducted a questionnaire investigation among 252 male patients with infertility, which involved the general condition, results of semen routine examination, sexual life, and scores in IIEF-5, self-reported 9-item patient health questionnaire (PHQ-9) and 7-item generalized anxiety disorder scale (GAD-7). We analyzed the prevalence of ED, depression, and anxiety and their correlations among the patients in comparison with 100 fertile male controls. RESULTS: In 245 of the infertility patients, the most common symptoms of depression and anxiety were "feeling tired or no vitality" and "easily getting worried or impatient", 20.4% of them with depression disorder and 42.9% with anxiety disorder. The PHQ-9 and GAD-7 scores were significantly higher in the infertile males than in the normal fertile controls (P <0.05), and so was the incidence of ED (28.6% vs 12.4%, P <0.05), while the IIEF-5 scores were markedly lower in the former than in the latter group (P <0.01), and so were sex frequency and sexual satisfaction (P <0.05). The PHQ-9 and GAD-7 scores were remarkably higher in the infertility patients with ED than in those without (P <0.01). Logistic regression analysis showed that the level of libido and results of semen routine examination were the risk factors for depression disorder, while age, education level, disease course and experience of assisted reproduction were those for anxiety disorder. CONCLUSIONS Male infertility patients have a poorer mental health and a higher incidence of ED than normal fertile men, and there is some interaction between psychological status and ED prevalence.

ObjectiveTo evaluate the effect of the oral-appliance combined with tadalafil in the treatment of erectile dysfunction (ED) induced by severe obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODSWe equally randomized 90 patients with severe OSAHS-induced ED to groups A, B, and C to be treated with the oral-appliance, tadalafil (10 mg daily qd), and oral-appliance plus tadalafil, respectively, all for 3 months. Then we compared the therapeutic effects among the three groups of patients using the IIEF-5 questionnaire, Sexual Encounter Profile (SEP) diaries, and the intercourse satisfaction rate of the patients' partners.

RESULTSTotally 87 of the patients accomplished the treatment, 29 in group A, 30 in B, and 28 in C. After treatment, group C, as compared with A and B, showed significant increases in the IIEF-5 score (4.18±1.19 vs 2.66±1.63 and 2.77±1.74, P=0.009 and P=0.026), the success rate of penile intromission (SEP2) (85.7% vs 58.6% and 53.3%, P=0.023 and P=0.008), and the success rate of intercourse (SEP3) (64.3%% vs 37.9% and 33.3%, P=0.047 and P=0.018). The overall satisfaction of the female partners was remarkably higher in groups A and C than in B (P=0.027 and P=0.007).

CONCLUSIONSOral-appliance combined with tadalafil can improve erectile function in patients with severe OSAHS-induced ED, with a better efficacy than either of them used alone.

ObjectiveTo investigate the correlation between the premature ejaculation diagnostic tool (PEDT) and International Index of Erectile Function-15 (IIEF-15) in different types of premature ejaculation (PE).

METHODSWe performed a cross-section survey among 352 PE patients received in the andrology clinic from December 2014 to December 2015 and 104 healthy men from the health examination center using basic demographic information (as on age, height, weight, education status, occupation, income, etc.), PEDT results, and IIEF-15 scores of the subjects.

RESULTSThe PE patients had remarkably higher PEDT and lower IIEF-15 scores than the healthy men (P<0.01). The PEDT score of the PE patients was negatively correlated with their total IIEF-15 score as well as with the scores in the domains of erectile function, sexual intercourse satisfaction, and overall satisfaction after adjusted for age (P<0.01). The patients with acquired PE (APE) showed a lower IIEF-15 score than those with lifelong PE (LPE) (P<0.01). The PEDT score of the APE patients was correlated negatively with the total IIEF-15 score (r=－0.391, P<0.01) and the scores in the domains of erectile function (r=－0.362, P<0.01) and overall satisfaction (r=－0.621, P<0.01), but not correlated with intercourse satisfaction, sexual orgasm, or sexual desire. The PEDT score of the LPE group was correlated negatively with intercourse satisfaction (r=－0.286, P<0.05) but not correlated with either the total IIEF-15 score or the scores in the domains of erectile function, overall satisfaction, sexual orgasm, or sexual desire.

CONCLUSIONSPE patients have a higher PEDT score and a lower IIEF-15 score than normal males. The PEDT score of APE patients is significantly correlated with the total IIEF-15 score, while that of LPE patients is correlated not with the total IIEF-15 score but with intercourse satisfaction.

ObjectiveTo study the psycho-social risk factors of sexual failure among newly married young males in the Uyghur population.

METHODSWe conducted a paired case control study of 186 newly married Uyghur young males (aged 17－30 ［23.4±2.9］ yr) with sexual failure and another 186 (aged 18－34 ［24.0±3.1］ yr) with no such problem as controls. We performed a logistic regression analysis on the possible psycho-social risk factors of this condition.

RESULTSLogistic regression analysis showed that the risk factors of sexual failure among the newly married men included personality (OR=0.271, 95% CI 0.176－0.420), income (OR=0.391, 95% CI 0.264－0.580), history of masturbation (OR=0.824, 95% CI 0.710－0.956), premarital sex (OR=0.757, 95% CI 0.677－0.847), sense of obligation (OR=1.756, 95% CI 1.157－2.693), equality of the social status (OR=0.574, 95% CI 0.435－0.756), degree of mutual care (OR=1.605, 95% CI 1.268－2.032), female's psychological obstacle (OR=2.832, 95% CI 1.221－6.569), and religion (OR=0.643, 95% CI 0.472－0.967). There was a statistical significance in the correlation between these factors and sexual failure in the newly married males (all P<0.05).

CONCLUSIONSSexual failure of newly married Uyghur young males are associated with many psycho-social factors, which necessitates sexual education among young males and particularly pre-marriage sexual education and psychological guide among both males and females.
