Excision necessary before IVF?

Any of you ladies out there with severe endo know if it’s necessary to have excision surgery before <a href="https://glowing.com/glow-fertility-program">IVF</a>? I was just diagnosed by lap with severe endo and she removed some but said it wasn’t safe to remove most of it as it was on my organs and blood vessels and everything was basically plastered together, this doc is not an excision specialist.. Now waiting for an appt with fertility clinic, but wondering if I should expect them to say that I should have excision surgery with a specialist, or if they think <a href="https://glowing.com/glow-fertility-program">IVF</a> could be successful without a more thorough excision. Just curious to hear if anyone else has been in this situation. It’s so tough waiting weeks and/or months to get appts to make a plan :( it’s been such a long road already, I was really hoping I’d have the surgery and be able to get pregnant on my own :(
