Page 3 of 4 Cheryl Chase, founder of the Intersex Society of North America, advocates a non-interventionist approach: No surgery unless it's medically necessary and let children decide for themselves if they want to have their genitals surgically changed. Chase says the problem is that early genital plastic surgery damages sexual sensitivity, produces genitals that are severely scarred, and it gives a message to the child that they are unwanted "as is."
