Abstract

Despite enormous progress in the understanding of human reproductive physiology, the underlying cause of male infertility remains undefined in about 50.0% of cases, which are referred to as idiopathic infertility. Human apurinic/apyrimidinic endonuclease 1 (ApE1) is a multifunctional protein that has an important role in the base excision repair pathway. The present study aimed to evaluate whether two functional ApE1 polymorphisms (−656T > G and 1349T > G) are associated with the susceptibility of female infertility. Blood samples were collected from 100 patients diagnosed with female infertility and 100 control subjects and genotyped by tetra-primer amplification refractory mutation system PCR (T-ARMS-PCR). The results indicated that individuals with the variant TG genotypes had a significantly increased risk of female infertility (p = 0.035, OR = 1.98, 95% CI = 1.04–3.74). Whereas, a significant association between 1349T > G polymorphism and female infertility risk was not observed (p = 0.1). Larger studies with more patients and controls are required to confirm the results.
