We present cases in which eugonadal men show a measureable objective improvement in functioning and symptoms after testosterone supplementation. Case report: After testosterone supplementation two eugonadal men (total testosterone>8.00 ng/ml) improved on nocturnal penile tumescence and rigidity monitoring (RigiScan®) with a 48.5 minutes increase (greater than 60% rigidity) at the base and 43.2 minutes at the tip compared to before supplementation. The second case an increase (greater than 60% rigidity) of 39.2 minutes at the base and 44.4 minutes at the tip. Furthermore International Index of Erectile Function (IIEF) and Aging Male’s Symptom (AMS) scale improved after initiation of testosterone treatment. Discussion: There seems to be a discrepancy between laboratory findings in eugonadal men and symptoms of hypogonadism such as objective nocturnal penile tumescence and rigidity, free testosterone and scores of questionnaires which address these symptoms. This inconsistency is discussed according to the literature. Conclusion: Controlled studies are desirable to verify that eugonadal men with testosterone deficiency symptoms can objectively and subjectively benefit from testosterone supplementation.","PeriodicalId":15029,"journal":{"name":"Journal of andrology","volume":"6 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44689453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: It was a descriptive and cross-cutting study which took place in CNHU HKM and Menontin district hospital over a period of one month from 15th May to 15th June 2016. Outcomes: 42.2% of the study population are faced with premature ejaculation. The average age of premature ejaculators was 39.0 years ± 13.5. The average intravaginal ejaculation latency time (IELT) among premature ejaculators was 7.8 min ± 8.4 against 11.95 min ± 8.9 for non-premature ejaculators. 74.9% of respondents’ partners were satisfied with the intravaginal ejaculation latency time of their spouse. Only 28.1% of premature ejaculators resorted to treatment at least once to improve their intravaginal ejaculation latency time. Conclusion: Premature ejaculation is a cross-cutting issue in the population but the absence of consensus on its parameters prevents a satisfactory research.","PeriodicalId":15029,"journal":{"name":"Journal of andrology","volume":" ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-0250.1000176","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48317130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Males with SCAs are known to have variability in their developmental profile. Aim of this paper is to illustrate clinical variability in the different SCAs. The sample was composed by 53 subjects (mean age=21.16 years, range: 13-54) with karyotype 47, XXY (73%), 49, XXXXY (7%), 48, XXYY (9%), mosaicism 47, XXY/48, XXXY (2%), 47, XYY (5%), 48, XXXY (2%), 49, XXXYY (2%). Only 5 subjects have been diagnosed prenatally (4 KS and 1 XXYY). Primary caregivers completed a comprehensive questionnaire detailing birth, medical, developmental and psychological history. Cognitive and behavioral assessment was performed with clinical interviews with DSM IV criteria and psychometric questionnaires (WISC-R, WAIS-R, CPM, Token Test, VABS, SCL90, and SCQ). Twenty-one sex and age matched subjects karyotypically normal were also evaluated from the behavioural point of view. Mean IQ in typical KS was 87.45 ± 2 ds (sd=20.12) range 45-123, VIQ 91.74 (sd=19.55) range 50-130 and PIQ 86.87 (sd=20.87) range 50-126.

In CPM KS subjects scored 27.75 (range 13-36) and 31.50 in the Token Test (range 21-35) while in CPM the other SCAs subjects scored 22.27 (range 10-35) and 22.50 (range 9-31) in the Token Test (p<0.05). VABS scores documented more marked impairment on adaptive behavior in atypical SCAs subjects. SCL90 documented an elevation of paranoid scale in the 70% of KS subjects and 50% of other SCAs. Autistic traits were present in 67% of the other SCAs subjects and in the 18% of KS at the SCQ.

Results: Prevalence of PE as a ‘sexual dysfunction’ according to the modified ISSM definition of was 3.3% (n=81), whereas the prevalence of PE as a ‘sexual complaint’ (i.e., men who estimated their time to ejaculation was occasionally very short, suffered to some extent from PE and had a lack of ejaculation control) was 14.5% (n=356). Men attributed PE predominantly to particularly high sexual arousal (75%) or a long time since the last sexual intercourse (53%), but less than one third of all men with PE (30%) considered PE a ‘disease’. Potential selfreported risk factors showed significant differences (P<0.05) for overweight (21% vs 30%), depression (9% vs 14%) and erectile dysfunction (3% vs 15%) between men without and with PE. Conclusions: All men perceived PE as a ‘sexual difficulty’ and suffered from a very short time to ejaculation and/or the inability to control that time.","PeriodicalId":15029,"journal":{"name":"Journal of andrology","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44846209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate expression changes of microRNA (miRNA) associated with stress-induced ageing in Leydig cells.Methods: Brown Norway rats were separated into three groups, young control group, stress group and age group. Physiological changes, including serum corticosterone and testosterone levels, 11β-HSD (11β- hydroxysteroiddehydrogenase) activity, GSH/GSSG (glutathione/glutathione disulfide) ratio and DNA damage after chronic stress treatment were tested by radioimmunoassay and Immunohistochemistry. Differentially expressed miRNAs in Leydig cells between young control group and stress group were identified by miRNA microarray analysis, followed by target prediction of miRNAs. Functional annotation of predicted targets of miRNA was carried out using GeneSpring software and miRNA-target gene interaction network was built by String software.Results: Under chronic stress, increased serum corticosterone levels and reduced testosterone levels were observed. Meanwhile, decline of 11β-HSD activity and GSH/GSSG ratio, increase of DNA damage were also shown in stress group. After performed miRNA microarray analysis, three differentially expressed miRNAs were screened out, including rno-miR-31a-5p, rno-miR-192-5p and rno-miR-191a-3p. Targets of them were mainly involved in apoptosis, cell cycle and transport. In miRNA-target gene interaction network, targets of miR-31a-5p (Tp53, Ywhae and Ndel1), and targets of miR-192-5p (Cdk2, Rac2, Stk3) were with higher degree.Conclusion: These data suggest a central role of miRNA-regulated gene expression in response to chronic stress, especially dys-regulation of rno-miR-31a-5p and rno-miR-192-5p play a vital role in ageing of Leydig cells in testis.","PeriodicalId":15029,"journal":{"name":"Journal of andrology","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70784218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interestingly, the lack of efficacy and toxicity are known major failure causes during pharmaceutical drug development. Toxicity screening is therefore a mandatory procedure during pharmaceutical development. Renal and hepatic toxicity are the most common toxicity matters encountered during the development of new compounds. Nonetheless, the male reproductive system may also be a target for drug toxicity. However, developmental and reproductive toxicology testing is rarely performed both in pre-clinical and clinical trial phases. As a result, there are several risks for human fertility brought on by putative toxic chemical compounds. As there is a low incidence of reproductive and testicular toxicity (TT) found at the early stages of pharmaceutical development, several companies devote the majority of research investments to more frequent areas of occurrence. Such prioritization has resulted in scarce rigorous efforts aimed at improving detection methods to understand the causes of TT. Pharmaceutical companies should include comprehensive studies and more precise methods for TT evaluation when developing new pharmacological drugs, and should focus on the effects of the new chemical compound on male’s reproductive functions.","PeriodicalId":15029,"journal":{"name":"Journal of andrology","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-0250.1000185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70784007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
