Gretchen-
Having a hyst is a hard decision for most. I am 26 and Honestly I didn't
hesitate.
There is no guaranteed cure for endo, only the hope that it will.
The reason why it might not work is because some of the ovary might be
missed.
I am not trying to discourage you just talk to your Doctor and See if he
has had good luck removing the ovaries. And if you do get one please
make sure your estrogen replacement is "plant"estrogen.
If you want to talk more about it feel free to e-mail me
