Testing when you start fertility treat??

We've been ttc for 2 years now with no luck. And we're in the process of starting <a href="https://glowing.com/glow-fertility-program">fertility treatment</a>. Our first apt is later this month. So far I've seen 2 gynos and a naturopath. I've had some bloods done for hormones like the day 2 and day 21 tests. I've also had my thyroid and a few other things tested. My BF has had a few SAs done and will have another before we go back to the dr. His SA came back normal with slower swimmers. Mine came back all good except very low progesterone.  
​I've also had a laparoscopy, hysteroscopy and D&C in June 2013 to remove endo, check my tubes and just check everything out. The results were; endo & cyst on my ovary was removed, my tubes are clear, I was diagnosed with adenomyosis and the surface of my uterus isn't smooth like it should be (possibly due to the adeno) 
​I've tried to do some google research and educate myself a bit before I go to the dr, but to be honest I'm not to sure where to starts. So I'm after some info or advice on things to ask the dr about when we go for our first appointment with a fertility specialist in a few weeks. So any advice or previous experiences would be great.
