对１５例正常生育男性和３８例精索静脉曲张不育男性精浆中附睾功能的特异性标记酶α－１．４－糖苷酶（α－Ｇ）活性进行测定，以探讨精索静脉曲张不育患者附睾功能有无异常以及精索静脉曲张程度、治疗效果与α－活性的关系。结果显示，精索静脉曲张不育患者α－Ｇ活性较正常人明显下降（Ｐ＜０．００１）；亚临床型以及临床各级精索静脉曲张者精浆α－Ｇ活性无差别。手术治疗病人中，精子质量无改善者精浆α－Ｇ活性较改善者降低更为明显。说明附睾功能异常及其异常程度与精索静脉曲张不育的形成和预后有一定的联系。亚临床型精索静脉曲张有必要积极治疗
The activity of α-1,4-glucosidase (α-G), a specific marker of epididymis, in 15 normal fertile men and 38 infertile men with infertile men’s seminal plasma was determined to investigate whether varicocele Educated patients with or without epididymis abnormalities and varicocele, the therapeutic effect and a-activity relationship. The results showed that α-G activity in patients with varicocele was significantly lower than the normal (P <0.001); subclinical and clinical varicocele at all levels of seminal plasma α-G activity was no difference. Surgical treatment of patients, no improvement in sperm quality seminal plasma α-G activity decreased more significantly improved. Epididymis dysfunction and abnormalities that explain the formation and prognosis of varicocele infertility have a certain connection. Subclinical varicocele is necessary for active treatment
