概要
OBJECTIVE
To assess the association between glutathione-S-transferase gene polymorphisms GSTT1, GSTM1 and GSTP1 and onset of azoospermia.
METHODS
Multi-PCR was used to detect GSTM1 and GSTT1 gene deletions. Polymorphisms of GSTP1 were determined with restriction fragment length polymorphism (RFLP) method in 236 azoospermia patients and 142 healthy fertile male controls.
RESULTS
The frequency of M1 (-/-) and P1 (Ile/Val or Val/Val) genotype was 24.65% in the control group, which was significantly higher than that of the patient group (15.68%, P=0.031). Frequency of M1 (-/-), T1 (+/+) and P1 (Ile/Val or Val/Val) genotype was 12.68% in the control group, which was significantly higher than that of the patient group (5.51%, P=0.014).
CONCLUSIONS
The M1(-/-) and P1(Ile/Val or Val/Val) genotype and the M1(-/-), T1(+/+) and P1 (Ile/Val or Val/Val) genotype are associated with reduced risk of azoospermia in ethnic Chinese Han population.
