So many questions you asked. But since I am much new to this infertility world. And I got to help women based on the knowledge I got either from the personal experience or over the forum discussion. As much as I know is that IVF works best with PCOS. I have read so much post where women had PCOS and they were having IVF. And many of them had a successful procedure. And yes egg quality does affect the results of IVF. It would be concerned about how many eggs got fertilized. And that would decide your success ratio.
