Abstract:
Objective to investigate the correlation between glutathione S- transferase gene M1,t1 and P1(GStM1,GStt1 and GStP1)poly-morphism and sperm DNA fragmentation index(DFI)in male patients with idiopathic infertile. Methods the study included 246 male patients with idiopathic infertility. Polymerase chain reaction(PCR)and polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP) were used to identify the genotype of GStM1,GStt1 and GStP1,respectively. Sperm DFI was analyzed by flow cytometry with acridine orange staining. Results the sperm DFI was significantly higher in GStt1 gene null type group than in GStt1 gene wild type group(P < 0.01);and there were no significant differences in GStM1 and GStP1 gene mutation type groups when comparing with the wild type group(P > 0.05). Conclusion GStt1 gene deletion was positive associated with the sperm DFI in male idiopathic infertile patients.
