Association between methylenetetrahydrofolate reductase C677T polymorphisms and male oligozoospermia, asthenozoospermia or oligoasthenozoospermia: a case-control study.

ABSTRACT: Mutation of methylenetetrahydrofolate reductase (MTHFR) C677T leads to the decrease of folate utilization and the impairment of spermatogenesis. This study attempts to investigate the association between MTHFR C677T polymorphisms and nonobstructive oligozoospermia, asthenozoospermia or oligoasthenozoospermia in the Chinese population. The study cohort comprised 189 patients diagnosed with oligozoospermia, asthenozoospermia or oligoasthenozoospermia, and 626 controls based on clinical examinations. The MTHFR c.677 genotype of all subjects was determined by fluorescence staining in situ hybridization and the significance of different genotype frequencies was further analyzed by Chi-square test. The results showed that the frequency of MTHFR 677 CT genotype in the oligozoospermia, asthenozoos
