advice?

I'm 42 and have a 22 year old and 17 year old. Got married on 12-13-14. DH has a 21 year old, 18 year old (who is married and die Nov 2) and a 7 year old. We have decided to try for one of our own. I stopped bc in Feb and my periods are regular. Before his 7 year old he had a vasectomy and then a reversal then he got his youngest. He bought (an expensive!) test for men from Walgreens and it showed he has low sperm count. I kinda got bummed. He called for an actual appt with the dr on the 9th. I'm worried they'll tell him his count is too low. I'm going back and forth on this whole idea now. He's 43. I really do want another baby and for it to be with my high school crush would be awesome. We've even talked about wanting twins lol  and of course I'm in my TWW which is making me really bitchy lately. Ha, I'm supposed to start AF the day he has his test. Would anyone keep trying, despite the cost and the fact that we won't really be able to retire when we want. That's not much of an issue. He said there's <a href="https://glowing.com/glow-fertility-program">IUI</a>, but I get freaked out about how much all these treatments can add up to.    <a href="https://glowing.com/glow-fertility-program">IVF</a> will not be an option. We just can't afford that. We make very good money. All the kids are working and/or in school. Maybe my TWW is driving me crazy. Would you all just keep trying and go the <a href="https://glowing.com/glow-fertility-program">IUI</a> route if recommended?  I know I ovulate so I don't really know how that works if it is the mans "fault".
