The pooled results showed that there was no significant association between <i>AHR</i> rs2066853</span> gene polymorphism and male infertility risk (A vs. G: OR = 1.08, 95% CI = 0.83-1.39; AA vs. GG: OR = 1.16, 95% CI = 0.65-2.04; AA vs. GA + GG: OR = 1.17, 95% CI = 0.66-2.07; AA + GA vs. GG: OR = 0.99, 95% CI = 0.85-1.15).
Subgroup analysis by study population revealed there was no associationbetween AhR Arg554Lys polymorphism and susceptibility to male infertility in Asian population (G versus A, OR (95%CI) = 1.099 (0.940-1.286); GG vs AA, OR (95%CI) = 0.982 (0.781-1.235); GA versus AA, OR (95%CI) = 1.220 (0.726-2.052); GG + GA vs AA, OR (95%CI) = 1.221 (0.740-1.982); GG versus GA + AA, OR (95%CI) = 1.087 (0.919-1.286)).
To examine whether Arg554Lys polymorphism in the gene for aryl hydrocarbon receptor (AHR) and/or Pro185Ala polymorphism in the gene for aryl hydrocarbon receptor repressor (AHRR) constitutes a susceptibility locus for dioxin-related male infertility.
