ABSTRACT

<p><b>Background</b>Currently available evaluation criteria for penile tumescence and rigidity have been fraught with controversy. In this study, we sought to establish normative Chinese evaluation criteria for penile tumescence and rigidity by utilizing audiovisual sexual stimulation and RigiScan™ test (AVSS-Rigiscan test) with the administration of phosphodiesterase-5 inhibitor.</p><p><b>Methods</b>A total of 1169 patients (aged 18-67 years) complained of erectile dysfunction (ED) underwent AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor. A total of 1078 patients whose final etiological diagnosis was accurate by means of history, endocrine, vascular, and neurological diagnosis, International Index of Erectile Function 5 questionnaire, and erection hardness score were included in the research. Logistic regression model and receiver operating characteristic curve analysis were performed to determine the cutoff value of the RigiScan™ data. Then, the multivariable logistic analysis was used in the selected variables.</p><p><b>Results</b>A normal result is defined as one erection with basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5% and base at least 50.5%, average maximum rigidity of tip at least 62.5% and base at least 67.5%, △tumescence (increase of tumescence or maximum-minimum tumescence) of tip at least 1.75 cm and base at least 1.95 cm, total tumescence time at least 29.75 min, and times of total tumescence at least once. Most importantly, basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5%, and base at least 50.5% would be the new normative Chinese evaluation criteria for penile tumescence and rigidity. By multivariable logistic regression analysis, six significant RigiScan™ parameters including times of total tumescence, duration of erectile episodes over 60%, average event rigidity of tip, △tumescence of tip, average event rigidity of base, and △tumescence of base contribute to the risk model of ED. In logistic regression equation, predict value P < 0.303 was considered as psychogenic ED. The sensitivity and specificity of the AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor in discriminating psychogenic from organic ED was 87.7% and 93.4%, respectively.</p><p><b>Conclusions</b>This study suggests that AVSS-RigiScan test with oral phosphodiesterase-5 inhibitors can objectively assess penile tumescence and rigidity and seems to be a better modality in differentiating psychogenic from organic ED. However, due to the limited sample size, bias cannot be totally excluded.</p>

ABSTRACT

Objective To detect the expression of HBV in human early embryos of infertility patients combined with hepatitis B virus (HBV) infection after undergoing in vitro fertilization and embryo transfer (IVF-ET) treatment,so as to provide reliable evidence for the vertical transmission of HBV through human germ cells.Methods We collected the abandoned early embryos of patients combined with HBV infection after undergoing IVF-ET treatment in the department of reproductive medicine of the First People's Hospital of Yunnan Province,total genomic DNA was obtained by single cell PCR,and then polymerase chain reaction (PCR) was used to detect the expression of HBV-DNA and covalently closed circular DNA of hepatitis B virus (HBV-cccDNA) in early embryos.Results Both HBV-DNA and HBV-cccDNA were detected in the early embryo among the mother or father or parents HBV infected patients.The positive detection rate of HBV-DNA in mother,father and parents HBV infected patients was 78.9%,76.3% and 100%,and the positive rate of HBV-cccDNA was 63.2%,78.9% and 100%.The difference between the mother and the father was not significant (P>O.05).However,the positive rate in parents HBV infected patients group was significantly higher than the mother or father group,showing a significant difference (P<0.05).Conclusion HBV can be transmitted from mother or father to early embryos via IVF-ET treament,and the risk of vertical transmission increases significantly when the couple are HBV infected.

ABSTRACT

ObjectiveTo analyze the clinical features,diagnosis and treatment of male idiopathic hypogonadotropic hypogonadism (IHH).MethodsClinical data of 92 male IHH cases were analyzed retrospectively.ResultsThe mean age at evaluation was 21.0 ± 3.2 yrs,and 52 patients were diagnosed with Kallman syndrome (KS; IHH with anosmia/hyposmia) while the remainder were normosmic IHH (nIHH).All had normal radiological imaging of the hypothalamic and pituitary areas.The level of serum LH,FSH and T was low,and the clinical parameters (development of secondary sexual characteristics,sexual function,and serum testosterone levels.) were significantly improved after hormone replacement therapy.ConclusionsDiagnosis and differential diagnosis of IHH can be clearly defined based on clinical features and laboratory results.Hormone replacement therapy is an effective treatment option.
