text: # Congenital estrogen deficiency
  
  Congenital estrogen deficiency is a congenital form of hypoestrogenism in which the body is unable to produce or use estrogens. Such conditions include:
  
  * Aromatase deficiency, a condition in which aromatase is absent and androgens cannot be converted into estrogens.
  * Estrogen insensitivity syndrome, a condition in which the estrogen receptor is defective and unable to respond to estrogens.
