CAH refers to a group of disorders that manifests with varying degrees of physical stigmata including virilization of female patients.

Dr. Dix Poppas - A Life Changing Journey: Preethi Davis

Amazing Patient Stories : Preethi Davis was born in India with a rare and complex congenital abnormality in which her reproductive, urological, and gastrointestinal systems were combined into a single opening. She underwent multiple surgeries and treatments in India, and while her doctors did the best they could, they were unsuccessful. Ultimately, Preethi’s parents were unable to care for her, and placed her in an orphanage for children with no hope.
