From Jeremy Steinberg
I think that there are other factors behind the finding that foreskin removal is linked to reduced HIV infection (6 August, p 5). Some people who have had their foreskin removed complain of decreased sexual drive. Perhaps circumcised men have a lower rate of HIV because they are having less sex.
The editor replies:
• Bertran Auvert reports that his study found exactly the reverse: circumcised men reported 18 per cent more sexual contacts than those uncircumcised.
