输精管结扎术是一种最安全、简单和有效的避孕方法。Alexander 等曾指出输精管结扎术引起精子抗体产生,该抗体复合物对机体有有害作用。Al-exander 和 Clarkson 的研究发现给猕猴行(Mac-aca fascicularis)输精管结扎并喂高胆固醇饮食,明显增加动脉粥样斑块形成。另外还发现给恒河猴(Macaca mulatta)输精管结扎9～14年,并定期喂低胆固醇饮食也证明了腹主动脉、髂动脉和颈动脉有动脉粥样硬化形成。上述发现使已做了结扎术或正计划做结扎术的男性产生了心理负担,也引 Vasectomy is the safest, simplest and most effective method of contraception. Alexander et al. Have pointed out that vasectomy causes the production of sperm antibodies that have a detrimental effect on the body. Al-exander and Clarkson’s study found that macrophages of Macaca acuminatus (Lactating Macaca fascicularis) were ligated and fed a high-cholesterol diet, significantly increasing atherosclerotic plaque formation. In addition, Macaca mulatta vasectomy was also performed for 9 to 14 years and regular low-cholesterol diet was also found to have atherosclerosis in the abdominal aorta, iliac artery and carotid artery. The above findings have placed a psychological burden on men who have already had a ligation or plan to have a ligation,
