摘要
目的:探讨谷胱甘肽S-转移酶T1基因多态性(GSTT1)与特发性无精子症和少精子症的关系。方法:按WHO手册标准,采用WLJY-9000伟力彩色精子质量检测系统对研究对象进行精液分析,根据精液检测结果将研究对象分成特发性无精子症组(n=34)、少精子症组(n=40)和正常对照组(n=53),各组研究对象年龄、吸烟史、饮酒史无统计学差异。基因组DNA来自研究对象提供的外周血有核细胞,采用聚合酶链反应(PCR)方法对研究对象GSTT1基因进行分型。结果:特发性无精子症组、少精子症组GSTT1缺失型基因频率分别为76.5%和72.5%,明显高于正常对照组(49.1%),差异有统计学意义(无精子症组vs正常对照组,OR=3.13,95%CI为1.20～8.16,P=0.020;少精子症组vs正常对照组,OR=2.53,95%CI为1.06～6.11,P=0.038)。结论:GSTT1基因多态性与特发性无精子症、少精子症有相关性;GSTT1缺失基因型是特发性无精子症和少精子症发病的危险因素。
Objective： To investigate the association of glutathioneS-transferase T1 （ GSTT1 ） gene polymorphism with azoospermia and oligospermia. Methods ： Semen samples from 34 patients with idiopathic azoospermia, 40 patients with idiopathic oligospermia and 53 healthy controls with normal sperm concentration and motility were assessed according to the standards of WHO. The GSTT1 genotypes were identified by muhiplex polymerase chain reaction （PCR） with peripheral blood DNA samples. Results： The frequencies of null GSTT1 genotypes in the patients with idiopathic azoospermia, idiopathic oligospermia and the healthy controls were 76.5%, 72.5% and 49.1%, respectively. There was a significant association between the null alleles of GSTT1 and idiopathic azoospermia （ odds ratio 3.13,95% CI 1.20-8.16, P =0.020） and idiopathic oligospermia （odds radio 2.53,95% CI 1.06-6.11, P =0.038）. Conclusion ： The null alleles of GSTT1 are a strong predisposing risk factor for idiopathic azoospermia and oligospermia.
