This study - unlike others - found no effect of age of circumcision on HIV acquistion, even if the circumcision took place after sexual activity began and after HIV was prevalent.
This suggests that circumcision itself is not the key factor.
So circumcising insertive men could readily increase HIV transmission to their partners.
Yet already this study is being touted as a reason for gay men to get circumcised.] Studies that claim to find a correlation between intactness and HIV transmission are not uncommonly misreported in a way that plays up the "protective effect".
The circumcised men were more likely to be married and to have more than one wife, less likely to have ever been with a sex worker, or with more than three sex workers.
