　　今日在悉尼进行的第4届国际AIDS协会会议上发表的一项研究令一些研究者受挫，他们本希望通过性后洗涤阴茎来达到像包皮环切一样的预防HIV效果。该实验有超过2500名未受割礼的乌干达男性参与者，实验发现性后用肥皂和水清洗并未降低感染HIV的风险。 

　　以前的研究显示男性包皮环切可以减少60%的性交感染HIV几率。 

　　当前研究中的男性呈HIV阴性，并且他们已经坚持18个月记录他们性后清洗的习惯了。几乎85%的人称他们每次都会清洗。大多数仅仅使用肥皂和水，纵然还有一些人同时也使用布或仅仅使用一块干布。 

　　“我们发现持续的清洗与HIV发生的下降并无关系。”乌干达Makerere大学的Fred Makumbi博士说。似乎那些使用更多水清洗的男性有更高的风险。同样地，那些立即清洗而不是过10分钟之后再洗的男性的感染率更高。尽管Makumbi称这一发现“很可能并不可靠”，他说，“看起来水的使用以及[立即]清洗可能便利了病毒的存活和阳性感染。”先前的研究已经发现女性阴道清洗与高HIV感染率之间有关联。 

　　“如果[阴茎清洗]可以替代[包皮环切]，那是非常好的。但是确实没有足够的证据可以证明这一点。”伊利诺伊大学的Robert Bailey教授说。

AUSTRALIA: Post-Sex Washing Doesn't Lower HIV Risk: Study

Australian Associated Press (07.25.07) - Wednesday, July 25, 2007Tamara McLean  

Researchers who had hoped post-sex washing of the penis might confer circumcision-like protectionagainst HIV infection were disappointed by a study presented today at the 4th International AIDS Society Conference in Sydney. The trial, involving more than 2,500 uncircumcised Ugandan men, found that washing with soap and water after sex did not reduce the risk of HIV infection.  

Previous studies have shown male circumcision reduces the risk of female-to-male HIV infection by 60 percent. 

The men in the current study were HIV-negative,and for 18 months they recorded their post-sex cleansing habits. Almost 85 percent reported washing every time. Most used only soap and water, though some also used a cloth or a dry cloth alone.  

"We found that consistent washing was not associated with a reduction in HIV incidence," said Dr. Fred Makumbi of Uganda's Makerere University. There appeared to be a higher risk for men who used more water during washing. Likewise, men who washed immediately instead of waiting more than 10 minutes had a higher rate of infection. Though Makumbi called this finding "possibly unreliable" he said, "It appears that the use of water and [immediate] cleansing may facilitate viral survival and positive infection." Earlier research had found vaginal cleansing associated with a higher HIV rates in women.  

"It would be nice if [penile cleansing] could be an alternative to [circumcision], but there's really not enough evidence to support it," said Professor Robert Bailey of the University of Illinois.
