采用两阶段抽样的方法，对山东省潍坊地区三个县农村采用输精管栓堵法节育术的受术者１５０５例进行了问卷调查。又从其中随机抽取１６．５％的受术对象２４８例采集精液做精子计数。研究结果表明，并发症总发生率为０．７３％。术后一年，精子消失率为８８．３％，９５％可信限为８４．２～９２．４％。按赵生才制定的标准，节育有效率为９５．９％，９５％可信限为９３４～９８．４％。调查发现，术后精子计数在４００万／ｍｌ以下的１９例受术者中，有６例女方仍然使用宫内节育器，７例正值哺乳期，５例未采用措施，１例不详。因此，作者指出，不能证明栓堵术后精子计数小于４００万／ｍｌ可以作为判定男性节育术有效的评价标准。作者认为，判定男性阻塞性节育术效果应以精液两次离心沉淀中精子消失为标准。
A two-stage sampling method was used to survey 1505 patients who underwent vas deferens blockage in the rural areas of three counties in Weifang, Shandong Province. Again from the random sample of 16.5% of 248 subjects collected semen sperm count. The results show that the overall complication rate was 0.73%. One year after surgery, the rate of sperm loss was 88.3% and the 95% confidence limit was 84.2-92.4%. According to the standard set by Zhao Sheng-cai, the effective rate of birth control was 95.9%, with a 95% confidence limit of 934-98.4%. The survey found that postoperative sperm count of 4 million / ml in 19 patients underwent surgery, 6 women still use IUD, 7 positive lactation, 5 did not take measures, an unknown. Therefore, the authors point out that it can not be proved that sperm count less than 4 million / ml after plugging can be used as an effective evaluation criterion for determining male contraception. The author believes that the determination of obstructive male sterility effect should be sperm semen centrifuged two centrifuge precipitation as the standard.
