近年,有人发现猴在输精管切除术后,动脉粥样硬化的患病率增加,而人类在术后并无类似改变。作者通过对血清脂质水平的研究对此进行探讨。 62名经输精管切除术绝育的男性,24～62岁,术前第7天和第15天及术后2,6和12个月分别测定体重和血压,同时静脉取血测定非酯化脂肪酸、总脂类、甘油三酯、总胆固醇及α、β、前β脂蛋白。结果示在输精管切除前后的男性平均体重和血压无明显改变,血清脂质各项平均值在术前与术后2、6和12个月时相比,无显著性差异。在二分之一或三分之二的接受输精管切除术男性当中,出现凝集和抑制精子运动的抗体,可能是因为附睾漏出可溶性精子抗原。这种抑制精子运
In recent years, it has been found in monkeys after vasectomy, the prevalence of atherosclerosis increased, while humans did not change after surgery. The authors explore this by studying serum lipid levels. 62 vasectomized men, 24 to 62 years of age, preoperative 7 days and 15 days and 2, 6 and 12 months after surgery were measured body weight and blood pressure, while venous blood determination of non-esterified fatty acids, Total lipids, triglycerides, total cholesterol and alpha, beta, pre-beta lipoprotein. The results showed no significant changes in mean body weight and blood pressure of men before and after vasectomy. The mean values of serum lipids did not differ significantly between preoperative and postoperative 2,6 and 12 months. Among one-half or two-thirds of men who underwent vasectomy, antibodies that agglutinated and inhibited sperm motility were likely due to the leakage of soluble sperm antigen by the epididymis. This inhibits sperm transport
