Can a woman still have healthy eggs after chemo?

I read and article of a young woman who had Ovarian Cancer and got treatment for it. She was at stage 3. One of her ovaries was removed but the other one is just fine. They say she will be able to have children some day still. So I was wondering if she had chemo and if she did, how does the eggs not get affected. Women are born with all of their eggs so that means she doesn’t make new ones. Won’t her eggs be damaged?
