Recent conflicting findings on possible health risks related to vasectomy have underscored the need for reliable and representative estimates of numbers and rates of vasectomies in the United States. The purpose of this study was to estimate the annual US number, rate, and characteristics of vasectomies in 1991.
A national survey of urology, general surgery, and family practice physician practices was conducted with probability sampling methods (n = 1685 physicians).
An estimated 493,487 (95% confidence interval = 450,480, 536,494) vasectomies were performed in 1991, for a rate of 10.3 procedures per 1000 men aged 25 through 49 years. Most vasectomies were performed by urologists, and most were done in physicians' offices with local anesthesia and ligation as the method of occlusion. The rate of vasectomies was highest in the Midwest.
This survey provides the first national estimates of the number and rate of vasectomies in the United States, as well as the first estimates of occlusion method used. Results confirm previous findings that urologists perform most vasectomies and that most vasectomies are performed with local anesthesia. Recommendations include the monitoring of vasectomy numbers and rates as well as demographic studies of men obtaining vasectomies.
近期关于输精管切除术可能存在的健康风险的相互矛盾的研究结果，凸显了在美国对输精管切除术的数量和比率进行可靠且具代表性估计的必要性。本研究的目的是估计1991年美国输精管切除术的年度数量、比率及特征。
采用概率抽样方法（n = 1685名医生）对泌尿外科、普通外科和家庭医学医生的执业情况进行了全国性调查。
1991年估计进行了493,487例输精管切除术（95%置信区间 = 450,480, 536,494），每1000名25至49岁男性中的手术率为10.3例。大多数输精管切除术由泌尿科医生进行，且大多数手术在医生办公室进行，采用局部麻醉并以结扎作为闭塞方法。输精管切除术的比率在中西部地区最高。
这项调查提供了美国输精管切除术数量和比率的首个全国性估计，以及所使用闭塞方法的首个估计。结果证实了先前的研究发现，即大多数输精管切除术由泌尿科医生进行，且大多数输精管切除术采用局部麻醉。建议包括监测输精管切除术的数量和比率，以及对接受输精管切除术男性的人口统计学研究。
