Purpose: Infertility is described as unexplained when all of the tests of a basic infertility evaluation return within normal limits and present in 15% of infertile couples. Some studies indicate that there is an association between methylenetetrahydrofolate reductase (MTHFR C677T and A1298C) mutations and unexplained infertility in male or female grown adults. The objective of this study was to analyze the distributions of MTHFR’s C677T and A1298C genotypes in couples with unexplained fertility problems (UFP) and healthy controls. Materials and Methods: Two common variants C677T and A1298C of the MTHFR gene were screened in infertile couples (n =60 for C677T polymorphism; n=62 for A1298C polymorphism) and controls from the Cukurova region of Turkey. C677T and A1298C mutations in the MTHFR gene were detected by the SNP analysis (Fragment analysis) kit of the multiplex PCR amplification/ligation products. Homocysteine levels (in serum) were determined by the human hcy ELISA kit and folate values were determined by the Beckman coulter Unicel DxI 800 chemiluminescence test kit at the Central Laboratory of Balcali Hospital in Cukurova University. Results: In this study, an association between unexplained infertility and MTHFR C677T polymorphism was not found. However, we found an association between MTHFR A1298C polymorphism and males with UFP (%7) and controls (%19). A statistically significant difference was observed between the infertile and control groups regarding i) the folate and homocysteine values of MTHFR C677T heterozygous individuals; ii) the homocysteine values of the MTHFR C677T normal individuals; iii) the homocysteine values of MTHFR A1298C heterozygous, normal and homozygous individuals; iv) the MTHFR C677T heterozygous and normal individuals; v) the homocysteine values of MTHFR C677T normal individuals; vi) the folate values of the MTHFR A1298C heterozygous and normal individuals. Conclusion: The etiopathogenesis of unexplained infertility remains largely unexplored. However, the relationship of the folate/homocysteine findings with the MTHFR polymorphisms under study is not clear. The results of our study support a relationship between the MTHFR A1298C polymorphism and male fertility problems. |
