Effect of MTHFR 665 polymorphism on plasma Hcy level and impact of Hcy level variation on sperm counts. (A) Box plot showing Hcy levels according to MTHFR 665 genotype. (B) Linear regression of sperm counts according to Hcy levels. Gray lines represent the 95% CIs of the sperm counts distribution and predictions. Hcy levels are expressed in μmol/L.
