Might want to ask WHO that question.
WHO | World Health Organization
"male circumcision should be considered an efficacious intervention for HIV prevention in countries and regions with heterosexual epidemics, high HIV and low male circumcision prevalence.
Male circumcision provides only partial protection, and therefore should be only one element of a comprehensive HIV prevention package which includes:
- the provision of HIV testing and counseling services;
- treatment for sexually transmitted infections;
- the promotion of safer sex practices;
- the provision of male and female condoms and promotion of their correct and consistent use."
... in lack of living in a mud hut in africa, it's safe to say that the -much more effective- methods of preventing HIV (condom use, regular std testing of partners, post-exposure prophylaxis) can do just fine.
Circumcised men can and do get HIV- and there's just as many studies which dispute the HIV benefit in circumcision as those which support it. Given that condoms are virtually always effective in preventing HIV, it is clear that the WHO's recommendations are aimed at countries with low rates of condom use or social acceptance and high rates of HIV: aka, mudhut countries in Africa. Places where -some- reduction in the risk of HIV is still harm reduction because HIV is so widespread. This is NOT the case in the US, and WHO policy should not be taken as US policy.
The WHO policy also allows for re-stitching female genital mutilation as long as it is not to a degree that would impede future sexual function, when one attends a childbirth where it needs to be open, because the WHO understands that women in such countries might not have a medical attendant at their birth if they fear their genitals will not be "returned to normal" after the birth. Likewise, the guidelines allow for women to ask to not have their FGM fully reversed, and the provider is not allowed to do a complete reversal even though we understand FGM is wrong and dangerous.
Does that mean they sanction female genital mutilation? Of course not. But they operate as best they can within the standards of where they are.
Playing in the sandbox you're in does not = recommending routine infant circumcision in developed countries with access to condoms, healthcare, post-exposure prophylaxis, etc.
