Do babies born with ambiguous genitals always need surgery immediately?

Not usually. Sometimes surgery is necessary to correct conditions that may be harmful to the baby’s health, but usually it is not medically necessary to perform surgery immediately to make the baby’s genitals appear more recognizably male or female. Parents, physicians, and intersex persons may have differing opinions about whether, how, and at what age surgery should be performed to change the appearance of ambiguous genitals. At this time, there is very little research evidence to guide such decisions.
