RESUMO

Objective@#To investigate the correlation of the single nucleotide polymorphism (SNP) rs4880 of the superoxide dismutase 2 (SOD2) gene with the risk of male infertility.@*METHODS@#This casecontrol study included 519 male patients with idiopathic infertility (aged 19-40 [28.93±4.93] years) in the case group and 338 fertile men (aged 19-40 [28.40±4.25] years) in the control group. We collected the clinical data, genotyped the SNP rs4880 of the SOD2 gene by Sequenom Mass Array, and analyzed the association of different genotypes with male infertility using the logistic regression model.@*RESULTS@#Statically significant differences were observed between the case and control groups in the level of folliclestimulating hormone (FSH) ([4.72±2.51] vs [15.65±17.24] U/L, P< 0.01), the percentage of progressively mobile sperm ([9.12±13.5] vs [41.95±9.03]%, P< 0.01), and sperm concentration ([12.95±24.38] vs [72.88±45.60] ×106/ml, P< 0.01), but not in other parameters. No correlation was found between male infertility and the heterozygous genotype TC (OR = 0.90, 95% CI: 0.65-1.25, P = 0.516) or the homozygous genotype CC (OR=1.49, 95% CI: 0.38-5.81, P = 0.566) as compared with the wild genotype TT, and similar results were obtained in the analysis of the subgroups.@*CONCLUSIONS@#The SNP rs4880 of the SOD2 gene was not correlated with male infertility, which, however, is to be supported by further studies with larger samples from more areas.

RESUMO

Objective@#To investigate the correlation of the single nucleotide polymorphism (SNP) rs1042522 of the tumor protein p53 (TP53) gene with the risk of male infertility.@*METHODS@#This casecontrol study included 380 male patients with idiopathic infertility and 398 normal fertile men as controls from the Nanjing area. We genotyped the SNP rs1042522 of the TP53 gene by Sequence Mass Array and analyzed the correlation of the SNP with male infertility using the logistic regression model.@*RESULTS@#Compared with the normal controls, the patients with idiopathic infertility showed significantly decreased sperm concentration ([77.34±49.24] vs [13.13±24.96] ×106/ml), percentage of progressively motile sperm ([42.55±9.57] vs [10.38±5.57]%), serum testosterone level ([14.07±5.36] vs [11.89±4.50] nmol/L), and folliclestimulating hormone level ([16.80±18.20] vs [4.55±7.17] U/L) (P < 0.05) but no statistically significant differences in other parameters. No correlation was observed between the SNP frequencies and male infertility and similar results were found in the subgroups of the cases.@*CONCLUSIONS@#SNP rs1042522 of the TP53 gene is not significantly correlated with the risk of male infertility.

RESUMO

<p><b>OBJECTIVE</b>To determine the correlation of the CYP1A1 (rs4646422) gene polymorphisms with male infertility in the Chinese Han population.</p><p><b>METHODS</b>Using the Mass ARRAY iPLEX GOLD technique, we conducted a case-control study on theCYPlA1 (rs4646422) gene polymorphisms in 636 infertile males aged 21-49 years (case group) and 442 normal healthy men aged 23-47 years (control group) of the Chinese Han population. We analyzed the genotypes and allele frequencies in the two groups ofsubjects with the SPSS 20.0 software.</p><p><b>RESULTS</b>Compared with the wild homozygous genotype GG, the heterozygous genotype AG (OR = 1.06, 95% CI 0.81-1.38) and homozygous genotype AA (OR = 1.11, 95% CI 0.56-2.21) showed no correlation with male infertility, nor did the mutant allele A (OR = 1.06, 95% CI 0.85-1.32) in comparison with the wild allele G.</p><p><b>CONCLUSION</b>The CYP1A1 (rs4646422) gene polymorphisms might not be correlated with male infertility in the Chinese Han population.</p>
