Dioxins (eg, 2,3,7,8-tetrachlorodibenzo-p-dioxin/TCDD), as environmental endocrine disruptors and toxic carcinogens, can affect male reproductive health. The influence of dioxins is mediated via the aryl hydrocarbon receptor (AhR) pathway and its repressor (AhRR). In this study, we investigated the association of AhRR-c.565C>Gtransversion polymorphism with male infertility. In a hospital-based case-control study, 221 semen samples (111 infertile and 110 healthy controls) based on World Health Organization guidelines were collected from in vitro fertilization centers of Babol, Iran. The AhRR-c.565C>G (rs2292596) polymorphism was genotyped using a polymerase chain reaction-restriction fragment length polymorphism analysis. The difference in the allele frequency of AhRR-c.565C>G transversion polymorphism did not reach a significant level. The genotype frequency was statistically significantly different between fertile and infertile men. We found that polymorphism rs2292596
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
