Background ― Genetic polymorphisms analysis of metabolic and antioxidant systems pathway genes are associated with male infertility is the most perspective and developed field in andrology. Purpose ― the aim of the research is to reveal the association of the glutathione S-transferase gene GSTP1 polymorphism C/T (rs1138272) with risk of pathospermia in Russian men in Moscow region. Material and Methods ― Case control study was conducted on 68 fertile men and 70 infertile men with various forms of pathospermia. Sperm analysis was performed according to WHO guidelines (WHO, 2010). DNA was extracted from peripheral blood leukocytes. Genotyping of the GSTP1 gene polymorphisms was carried out by generated amplicons from melting curve analysis after real time PCR. Results ― statistically significant association of polymorphism GSTP1 C/T (Ala/Val; rs1138272) with asthenozoospermia (χ2=8.58, p=0.003) and teratospermia (χ2=6.81, p=0.009) risk was found. The frequencies of homozygous and heterozygous carries (CT+TT genotypes) for polymorphic locus GSTP1 gene (rs1138272) are 3 times higher for men with disturbance of motility of spermatozoa and 2.5 times higher for men with abnormalities in morphology of spermatozoa, then for men with normozoospermia. Conclusion ― The GSTP1 C>T polymorphism (rs1138272) associated with risk of teratospermia and asthenozoospermia in male of reproductive age.
