【摘要】 目的：测定精子中3β-羟基甾体脱氢酶（HSD）。方法：采用酶组织化学方法对27例精子活率正常和20例精子活率低下的男子精子进行了研究。结果：3β-HSD主要分布在精子颈部，其着色面积不等，精子活率正常组3β-HSD着色面积为616．48±108．48μm2／100个精子，精子活率低下组为354．37±50．58μm2／100个精子，两组差异极显著（P＜0．001）。结论：3β-HSD可能通过某种途径间接参与精子的运动。更多还原

【Abstract】 Objectives and Methods: 3β-HSD of spermatozoa in 27 men with normal sperm motility and 20 men with asthenospermia was studied by method of enzymatic histochemstry. Results: 3β-HSD was mainly located in the neck of spermatozoa. There was a significant difference concerning the stainig area of sperm between two groups. The staining area in the group of normal sperm motility was 616. 48±108. 48 μm2/100 spermatozoa; that of the group of low sperm motility was 354. 37± 50. 58 μn2/100 spermatozoa. Significant difference was detected between the group of normal sperm motility and the group of low sperm motility (P＜ 0. 001). Conclusions: It suggested that 3β-HSD may be indirectly associated with sperm movement via an unknown pathway.更多还原
