分析当前男性节育的方法,无论是药物的、手术的或是工具的方法,总不外乎是三个方面的作用,即破坏精子的生成,切断精子逸出的通路,以及防止精子和卵子的结合。通常所用的男用避孕药物,如我国首创的男用口服避孕药棉酚等,是属于第一种情况,但是由于睾丸内存在着“血睾屏障”的阻挡作用,必须用大剂量的药物,才能起作用。而药物剂量加大,会带来副作用,这就在一定程度上限制了药物的使用。目前大量采用的输精管结扎手术和粘堵术等节育方法,是用机械的手段进行“断桥毁路”的方法。避孕套等工具的使用,则是为了不让已经逸出体外的精子进入女方和卵子结合而达到节育 Analysis of current methods of male birth control, whether drug, surgical or tool methods, are nothing more than three aspects of the role of the destruction of sperm production, cut off the path of sperm escape, and to prevent the sperm and egg Combined. Commonly used male contraceptives, such as China’s first male oral contraceptive gossypol, belong to the first case, but because of the testis there is a “blood testis barrier” blocking effect, we must use large doses of drugs to kick in. The drug dose increases, will bring side effects, which to some extent, limits the use of drugs. At present, a large number of methods of birth control such as vasectomy and sticking surgery are methods of mechanically breaking roads by breaking bridges. The use of condoms and other tools, is to prevent escaping from the body of the sperm into the woman and the egg to achieve birth control
