To be clearer, the study shows no significant difference in rates of transmission, though it is true as you say that eight more women in the circumcision group contracted the virus, something that is alarming all on its own. 

I suppose that if circumcision were consistently found to decrease men's risk of acquiring the virus it could be argued to decrease the risk to the women who have sex with them, but it seems to early to be able to say that with confidence. Condom use still seems necessary... and more effective.

A question I have is about whether men (or women) in the US are particularly resistant to the use of condoms on a regular basis.
