1) Almost no-one in Europe circumcises unless they're Jewish or Muslim, yet they have lower rates of STI's.
2) Female genital hygiene is far more complicated than male genital hygiene, but we don't cut parts off baby girls to make it easier.
3) Health benefits? This is what some national medical organizations say:
Canadian Paediatric Society
"Recommendation: Circumcision of newborns should not be routinely performed."
"Circumcision is a 'non-therapeutic' procedure, which means it is not medically necessary."
"After reviewing the scientific evidence for and against circumcision, the CPS does not recommend routine circumcision for newborn boys. Many paediatricians no longer perform circumcisions."
Royal Australasian College of Physicians
"After reviewing the currently available evidence, the RACP believes that the frequency of diseases modifiable by circumcision, the level of protection offered by circumcision and the complication rates of circumcision do not warrant routine infant circumcision in Australia and New Zealand."
(almost all the men responsible for this statement will be circumcised themselves, as the male circumcision rate in Australia in 1950 was about 90%. "Routine" circumcision is now *banned* in public hospitals in Australia.)
British Medical Association
"to circumcise for therapeutic reasons where medical research has shown other techniques to be at least as effective and less invasive would be unethical and inappropriate."
The Royal Dutch Medical Association
"The official viewpoint of KNMG and other related medical/scientific organisations is that non-therapeutic circumcision of male minors is a violation of children's rights to autonomy and physical integrity."
"[30 September 2013] - At a meeting today in Oslo, the children's ombudspersons from the five Nordic countries (Sweden, Norway, Finland, Denmark, and Iceland), and the children's spokesperson from Greenland, in addition to representatives of associations of Nordic paediatricians and pediatric surgeons, have agreed to work with their respective national governments to achieve a ban on non-therapeutic circumcision of underage boys."
German Pediatric Association
"Therefore it is not understandable that circumcision of boys should be allowed but that of girls prohibited worldwide. Male circumcision is basically comparable with FGM types Ia and Ib that the Schafi Islamic school of law supports"
"The other claimed health benefits, including protection against HIV/AIDS, genital herpes, genital warts, and penile cancer, are questionable, weak, and likely to have little public health relevance in a Western context, and they do not represent compelling reasons for surgery before boys are old enough to decide for themselves."
(Written in direct response to the AAP's position statement on male circumcision, and signed by 38 senior physicians, about half of them presidents or chairs of national paediatric or urological organisations).
