  ABSTRACT: Aim of the study: Examing the role of Methylene tetra-hydrofolate reductase (MTHFR C677T) polymorphisms in unexplained female infertility. Methods: The study was conducted on women with unexplained infertility attending the Infertility Clinic at El-Shatby University Hospital, Alexandria, during the period from October 2020 to October 2021. Uterine artery Doppler assessment and detection of MTHFR C677T gene mutation were done. The frequencies of homozygous and heterozygous gene mutations were determined. Results: In group I, 35 cases had abnormal uterine artery Doppler compared to 22 normal cases in group II. As regards MTHFR C677T gene mutation, 19 cases were positive in group I (7 were homozygous and 12 were heterozygous) and only one case was positive in group II (heterozygous) which was statistically significant. Conclusion: MTHFR C677T gene polymorphisms may play a role in unexplained infertility.
