Recently Journal of law,  medicine and ethics published a report that parental consent for newborn male circumcision is both legal and ethical. Please see report below:

"Newborn male circumcision is a minor surgical procedure that has generated significant controversy. Accumulating evidence supports significant health benefits, most notably reductions in urinary tract infections, acquisition of HIV and a number of other sexually transmitted infections, penile cancer, phimosis, paraphimosis, balanitis and lichen sclerosis. While circumcision, like any surgical procedure, has risks for complications, they occur in less than 1 in 500 infants circumcised and most are minor and require minimal intervention. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) believe that health benefits of circumcision outweigh the risks. For this reason, the AAP believes that parents should be allowed to make the decision concerning circumcision of their male infants after receiving non-biased information on health risks and health benefits."
