en who have been circumcised may be six times less likely to contract the HIV virus than uncircumcised men, research carried out in India suggests.
If we had a vaccine that reduced infection 6-fold we'd be singing in the streets. This is damned amazing -- if true. It seems too great an effect to be real.
But if it is ...
Whack 'em off. (ouch!)
PS. I've circumcised lots of (male) babies. It's pretty barbaric, though nowadays we at least use anaesthetics. I hated it, but figured it was an American cultural tradition I just had to put up with. Now it looks like there might be an amazingly good reason to lose the foreskin. Circumcising adults is more challenging.
