Babies with CAH, or Congenital Adrenal Hyperplasia, are often born with uterus and ovaries, but their genitalia may appear masculinized with a shallow vagina present. CAH is caused by the adrenal gland failing to make an enzyme needed for regulating androgen, aldosterone, and cortisol. People with CAH may suffer from severe salt-wasting which can be life threatening if not treated.
