MTHFRC 677T Gene Polymorphism and Homocysteine in North China Patients with Varicocele

Figure 2

Comparison of plasma homocysteine content, sperm motility, sperm density, MDA in seminal plasma, and PO₂ in spermatic vein between different genotypes of MTHFR C667T in VC group and NC group. The difference of plasma homocysteine content, sperm motility, sperm density, and MDA in seminal plasma between the VC–CC and NC–CC groups was not significant ( ; a–d), while (a) the VC–CT and TT groups had higher lasma homocysteine content () and (b, c) lower sperm motility and sperm density compared to the NC groups ( ). (d) MAD content was not significantly different in the VC–CT and NC–CT groups ( ), while the CT–TT group was significantly higher than the NC–TT group (). (e) And for PO₂ levels, VC–CC was significantly higher than both VC–CT and VC–TT groups ().
