Circumcision is an effective means for reducing HIV infections in Africa. It has been endorsed by the WHO. It should be practised all over the world to help to prevent the spread of HIV.
I just read the WHO's recommendations and you're oversimplifying it's position. They recommend circumcision for "countries with high rates of heterosexual HIV infection" not the entire world. Furthermore, the WHO claims that circumcision reduces the risk of infection by 60%, but other agencies dispute that figure. Some argue that circumcision offers little or no protection, and may actually increase the risk.
So if you consider the United States, for example, you're talking about circumcising millions of men, many of whom aren't even at risk, in order to prevent--at best--a few thousand HIV infections. It would be far more effective and economical, for men who are at risk of contracting HIV to use condoms, plus there would be no risk of the physical or psychological problems
caused by circumcision.
None of the following medical organizations recommend the practice of non-therapeutic circumcision:
American Medical Association
American Academy of Pediatrics
American Academy of Family Physicians
Canadian Paediatric Society
Royal Australasian College of Physicians
Australian Association of Paediatric Surgeons
Australasian Association of Paediatric Surgeons
Australian Medical Association
Australian Paediatric Association
New Zealand Society of Paediatric Surgeons
Urological Society of Australasia
Paediatric Society of New Zealand
British Medical Association...
and a whole bunch of other British organizations. It's late and I'm too tired to keep typing, but I probably could find more.
