Seminal plasma anti-Müllerian hormone and inhibin B and serum inhibin B in predicting the outcome of routine IVF fertilization / 中华男科学杂志

Objective@#To analyze the correlations of seminal plasma (sp) anti-Müllerian hormone (spAMH) and inhibin B (spINHB) and serum INHB (serINHB) with semen parameters in oligoasthenospermia patients and explore their value in predicting the outcome of routine in vitro fertilization (IVF).@*METHODS@#We obtained the levels of spAMH, spINHB and serINHB as well as semen parameters from 88 infertile males undergoing IVF due to oligoasthenospermia or female uterine tubal factors from August 2016 to February 2017. Using the ROC curve and Pearson's correlation analysis, we examined the effects of the obtained parameters on the fertilization rate and assessed the correlation of the levels of spAMH, spINHB and serINHB with the semen parameters of the patients.@*RESULTS@#Concerning the predictive value for the outcome of IVF, Pearson's correlation analysis showed that the area under the ROC curve (AUC) of spAMH was 0.807 (sensitivity = 84.6%, specificity = 76%, cut-off point = 3.529, P <0.001) and that of spINHB was 0.768 (sensitivity = 84.6%, specificity = 88.7%, cut-off point = 31.117, P = 0.002). The serINHB level was found positively correlated with sperm concentration (r = 0.346, P = 0.001), total sperm count (r = 0.378, P <0.001), sperm motility (r = 0.521, P <0.001), and the percentage of progressively motile sperm (r = 0.343, P = 0.001).@*CONCLUSIONS@#The levels of spAMH and spINHB can be used as laboratory indexes to predict the fertilization rate of routine IVF and are correlated with semen parameters in oligoasthenospermia patients, while that of serINHB has a positive correlation with the semen parameters of the patients.

Relationship between ERCC2 single nucleotide polymorphisms and male idiopathic infertility in Ningxia / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the influence of the DNA repair gene ERCC2 single nucleotide polymorphisms (SNPs) rs13181, rs1618536, and rs1799793 on male idiopathic infertility in Ningxia, China.</p><p><b>METHODS</b>Using MassArray, we conducted a case-control study and genotyped three ERCC2 SNPs rs13181, rs1618536, and rs1799793 for 351 males (aged 31.0 +/- 4.2 years) with idiopathic infertility and another 327 normal fertile men (aged 33.0 +/- 5.9 years) as controls.</p><p><b>RESULTS</b>The ERCC2 AnyG-anyA-anyA genotypes were significantly associated with an increased risk of idiopathic infertility (OR 0.414, 95% CI 0.176 - 0.970), while the three single ERCC2 SNPs rs13181, rs1618536, and rs1799793 showed no significant differences between the cases and controls (P > 0.05).</p><p><b>CONCLUSION</b>The ERCC2 SNPs rs13181, rs1618536, and rs1799793 play a role of interaction in male idiopathic infertility in Ningxia, contributing to the risk of the disease.</p>
