Congenital estrogen deficiency
# 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.
