As someone who is suffering from PCOS, myself, I can just tell her that it's not the end of the world. There are solutions available. She shouldn't lose hope. You're doing the right thing by suggesting her IVF. It almost definitely works with PCOS. Good luck to your friend. If she's reading this, just let her know that she shouldn't feel alone, there are many women out there who are going through this, and that she can do this!
Sorry to hear about your condition. Just know that you are not alone. This actually happens to more people than you think. Its good to know that you are handling it well. My friend couldn't conceive the first time. But she finally did after the second transfer. It all worked out.
