Ambiguous genitalia is a rare condition where a baby is born with genitalia (sexual organs) that are not clearly male or female. About 1 in 4,500 babies is born with ambiguous genitalia, which is usually diagnosed by a doctor at birth. With ambiguous genitalia, the baby's sexual organs may not be fully developed and the baby may have characteristics of both sexes, or the internal sexual organs might not match the external sexual organs. Ambiguous genitalia may be caused by abnormal amounts of hormones (important chemicals) during development. The steps for managing ambiguous genitalia depend on the family's choice, but it is important to have genetic testing to determine whether or not the condition is caused by mutations to certain genes or missing or extra chromosomes. In some cases, surgery to correct ambiguous genitalia or hormone medication may be used, but these options are not for everyone. Most children with ambiguous genitalia are otherwise completely healthy. Talk with your baby's doctor as well as genetic and other specialists to determine the best care plan for your child. Connecting with other families affected by ambigous genitalia may also be helpful.
