The ban on the circumcision of boys in many Australian public hospitals has come under fire from 12 medical experts who say the latest evidence from around the world shows the procedure reduces risk of infections, cancer and painful conditions.

More than 80 per cent of Australian boys are uncircumcised, exposing them to significantly higher risk of urinary tract infections in childhood and in later life to other diseases including prostate cancer and, in their female partners, cervical cancer, their study finds.

The research leader, a Sydney University professor of medicine, Brian Morris, said it was the most comprehensive assessment of international evidence on the issue yet.

He said the evidence in favour of infant circumcision was so strong it made this simple procedure for baby boys about as effective and safe as childhood vaccination.
