What is circumcision?
The procedure of removing the foreskin of a newborn male's genitalia has been practised for religious and cultural reasons for centuries. It is a common practice among Jewish, Muslim and some Christian communities but is also undergone for cultural reasons as a mark of cultural identity. For Jews and Muslims, the practice is stipulated in religious texts. It's also been a practice among Indigenous Australians communities.
Benefits vs risks
The World Health Organisation (WHO) says neonatal, infant and child circumcision is generally safe if it is conducted by experienced providers in hygienic conditions, but there have been levels of risk outlined in some studies of child circumcision by medical providers.
The Royal Australasian College of Physicians (RACP) says while there is evidence that shows health benefits, there are also some risks from the medical procedure. It considers the potential health benefits are not sufficient to recommend routine circumcision of all infant males.
The RACP cites recent studies as showing circumcision may provide protection against urinary tract infections in infancy. Also in countries where sexually transmitted disease is high, the procedure can also reduce the risk of HIV/Aids.
How many people are circumcised?
In a 2010 report, the WHO estimated one in three males worldwide were circumcised. In Australia, it said 59 per cent of men were circumcised.
But there is evidence showing that is substantially declining with new generations.
Based on Medicare records, there were 6309 newborn males circumcised in the 2016/17 financial year.
That is a major drop from the 19,663 circumcisions of babies under six months of age from 2007/08.
RACP paediatrics and child health division's Professor Paul Colditz says the rates were four times greater a decade earlier and the numbers have been dropping rapidly.
"Only four per cent of boys are being circumcised so I guess parents are really making up their own minds on the basis of the available evidence," he told SBS News.
However, there may be a small number not captured by the data given it is based on Medicare claims for the procedure.
But Professor Colditz says that would be a fairly small number in relation to the 6000 babies circumcised in the past year.
"There will be a small number done by religious figures who may be very experienced," he said.
Why are rates dropping?
Professor Colditz says it is because of two aspects - more informed parents and more fathers not being circumcised themselves.
"The number of new fathers who are no longer circumcised is increasing and therefore if they haven't been circumcised, collectively between the two parents then they're making a decision that they don't feel it will confer any benefit to their son," he said.
Parents were also making up their own minds by researching available evidence.
"We've entered an era where everyone is looking at [it like], 'Is this operation, is this treatment worthwhile, will be effective, what are the risks?'" he said.
“[They're] doing this balance between the potential for any benefits against the potential for any harm and I think the whole of society is getting sophisticated in the way they do this."
