Abstract
Aim: To investigate the association between serum homocysteine (HCY) levels, red blood cell folate (RCF) levels, methylenetetrahydrofolate reductase (MTHFR) gene polymorphism and infertility.Materials & methods: Serum HCY and RCF levels and C677T polymorphism of MTHFR gene were analyzed in 149 infertile patients and 223 women of normal reproductive age with healthy childbirth history.Results: The HCY level of MTHFR C677T TT genotype infertility patients was higher than that of women of normal reproductive age, while the RCF level was not significantly different between the two groups.Conclusion: Serum HCY levels increased in infertility patients, and the MTHFR C677T TT genotype in childbearing-aged women are associated with a higher risk of infertility. The results showed that HCY level and MTHFR C677T genotype were closely related to infertility.
