Introducing myself - PCOS, endometriosis and Hashimoto

Hello all. I’ve been perusing the boards for many months now and feel it’s time to jump in too. I’m 36 and DH is 40 turning 41 in a few months. We’ve been TTC for 15 months but since we are both AMA we’ve recently visited a RE. I’ve been dx with PCOS and Hashimoto which I take 100mg levithyroxine and 100mg (or mcg I can never remember) metformin to manage. The main issue is that I’m not ovulating. We did 50, 100 and 1 round of 150 before doing laparoscopy this past March. During the procedure my OB discovered tubes were clear, cysts were drained and stage 2 endometriosis was also found and cleared out. We then did another round of 150 clomid and I still did not ovulate. DH has a slight male factor, I’m not sure the exact numbers, but Dr. said it’s not terribly bad but the fact that neither of us has had children, I’ve never been pregnant before and he’s never impregnated anyone are all wild cards in our situation. The RE has given us the option of IUI or IVF and I have a 9.4 AMH level. Our insurance does not cover anything for infertility and after getting as much info as I could from one of the nurses in the RE’s office she said that couples with our circumstances usually at least try one round of IUI. As we all know, BFNs are the worst and I can only imagine how devistating it would be to go through an unsuccessful IUI but I would also always wonder if we could have saved some and gone with IUI. I’m currently leaning toward trying the IUI. I would greatly appreciate any insight offered and welcome all opinions.
