在四川省成都市远郊的7个公社,对4,596名已做输精管结扎和4,340名未做输精管结扎的农民进行了一次输精管结扎术对心血管系统的远期影响的回顾性定群研究。结扎者平均结扎年限为14.5年,范围10～25年。研究结果:结扎者在心血管临床症状、静息心电图改变,踏车运动试验,心电图阳性及眼底异常等广泛的健康指针方面,普遍的较未结扎者为佳。本次研究是在心血管疾病发病率低和危险因素也低的人群中进行的,结果表明输精管结扎术远期没有危害健康的作用。
A retrospective cohort study of the long-term effects of a vasectomy on 4,596 azoospermia ligation and 4,340 unveiled vegetative tracts was performed in 7 communes in the outskirts of Chengdu, Sichuan Province. The ligation group had an average ligation period of 14.5 years and a range of 10 to 25 years. RESULTS: The ligation group was generally better than the non-ligated group in terms of clinical symptoms of cardiovascular disease, changes in resting electrocardiogram, treadmill exercise test, positive electrocardiogram and abnormal fundus. This study was conducted in a population with low incidence of cardiovascular disease and low risk factors. The results showed that vasectomy had no harm to health in the long term.
