Abstract

Background: Pi-GST and Mu-GST are subclasses of GLUTATHIONE S-TRANSFERASE that present on human SPERM surface and play an important role against oxidative stress. Therefore, any defects in the enzyme activity may be associated with MALE INFERTILITY.In this study the polymorphisms of GSTM1 and GSTP1 in association with enzyme activity and SPERM parameters were studied.Methods: This case-control study involved 95 men with oligoastenoteratozoospermia and 26 controls with normozoospermia. Semen analyses were carried out according to WHO guidelines. Blood DNA was extracted using salting out procedures. GSTM1 and GSTP1 POLYMORPHISMs gene were determined through PCR-RFLP and multiplex PCR, respectively. Finally, GLUTATHIONE S-TRANSFERASE activity was measured.Results: Frequencies of GSTM1 null genotype in oligoastenoteratospermic and normospermic groups were 52.1% and 53.8% respectively. There were no statistically significant differences in SPERM parameters and enzyme activity between GSTM1 null and positive genotypes in two groups. There were no statistically significant differences in GLUTATHIONE S-TRANSFERASE activity between oligoastenoteratospermia and normospermic groups (p>0.05). All the 121 men in this study had Ile/Ile genotypes at 105 codon of GSTP1. Frequency of normal homozygote (114Ala/Ala), heterozygote (114Ala/Val) and mutant homozygote (114Val/Val) genotypes in oligoastenoteratospermic group were 81.1%, 17.9% and 1.1% respectively but in the control group they were 88.5%, 11.5% and null.Conclusions: Total GLUTATHIONE S-TRANSFERASE activity and SPERM parameters were not affected by deficient GLUTATHIONE S-TRANSFERASE activity in GSTM1 null genotype. Compensate activity of other SPERM surface GLUTATHIONE S-TRANSFERASE isozymes, like GSTP1, may justify the cause.
