title: GSTT1 and GSTM1 polymorphisms are associated with improvement in seminal findings after varicocelectomy.
abstract: To identify the best candidates for varicocelectomy, we evaluated the genetic polymorphism in glutathione S-transferase (GST) T1 and M1 in 38 infertile men with high-grade varicocele testis who underwent varicocelectomy. The response rate to varicocelectomy is significantly higher in patients with the GSTT1-wt genotype than the GSTT1-null genotype, and the response rate became higher in combination with the GSTM1 genotype.
