Abstract
Meta-analysis Polymorphism Studies of the relationship between male infertility and CYP1A1 polymorphisms are inconclusive. To drive a more precise estimation, we performed a meta-analysis based on 1,060 cases and 1,225 controls from 7 published case-control studies. PubMed and CNKI literature search were conducted to identify all eligible studies investigating such a relationship. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association in the additive model, dominant model, recessive model, and allele-frequency genetic model. In the overall analysis, the frequency of CYP1A1*2A genotype was significantly associated with susceptibility to idiopathic male infertility. Further stratified analysis by ethnicity showed notable association between the polymorphism and risk of idiopathic male infertility in Asians. In conclusion, these results support that the CYP1A1*2A genotype polymorphism mainly contributes to idiopathic male infertility susceptibility in Asians but not in Caucasians.
