Hey I am in a similar situation and maybe can help shed some light to your infertility issues 
I actually had UC ages 13-20 and had my Jpouch done in 2006. So here I am 10 years later and my hubby and I've been trying for the past 12 months as well with no luck. We've been to fertility docs and I have a wonderful ObGyn. She is now suggesting that I have a laporoscopy prior to spending $20,000 on IVF to see how things look. My tubes are patent per the HSG, but the Ob feels like the ovaries may be spun in scar tissue. My GI also reminded me of the high risk of infertility because of our surgery but that a newish study found that pregnancy rates among women with JPouch and pregnancy rates in the general population are essentially the same with IVF. I'll probably go forward with the lap simply bc it's the last step before IVF without costing me thousands. Good luck to you... and please know you're not alone in this struggle. It's a sad thing at times I know ❤️ All you can do is keep on keeping on, which any girl with our history is an expert at doing!
