2007年7月10日《公共科学图书馆·医学》(PLoS Medicine)发表的一项研究成果表明:男性包皮环切能够减少60%的艾滋病感染几率。世界卫生组织也给予了极大的关注。其相关机理可能为:①艾滋病病毒是极易被氧化而丧失功能的,在常温下空气中的氧就可以有效地抑制或杀灭艾滋病病毒(也可能是空气中的其它气体起作用,但这种可能性较小,因那些气体都是惰性气体)。②男性包皮过长造成局部相对无氧,可使感染的艾滋病毒长期藏身于其中,有利于其繁殖并侵入皮肤。
A study published in the July 10, 2007, issue of the journal PLoS Medicine shows that circumcision in men reduces the chances of a 60% HIV infection. The World Health Organization has also given a great deal of attention. The relevant mechanism may be: ① HIV is extremely vulnerable to oxidation and loss of function, at room temperature, oxygen in the air can effectively inhibit or kill the AIDS virus (may also be the role of other gases in the air, but It is less likely that those gases are inert gases. ② male overcast caused by the local relative lack of oxygen, HIV can be infected for a long time to hide in them, is conducive to their breeding and invade the skin.
