Congenital estrogen deficiency

Okay kiddo, so there's something called estrogen which is a hormone that girls and women have that helps them grow and develop into who they are as they get older.

However, some girls can be born with something called congenital estrogen deficiency which means they don't have as much estrogen as they should. This can make it harder for them to grow certain parts of their body like their uterus and breasts.

It can also make it harder for them to do things that girls with more estrogen can do like getting their period or having a baby when they grow up.

But don't worry, there are ways to help girls with congenital estrogen deficiency. They can take special medicine with estrogen in it to help their body grow and develop like it should.
