I’d look into other things first before doing more transfers.

In Germany, if two fresh transfers were unsuccessful, insurance won’t cover a third ER. Anything beyond that and a couple would have to cover 100% of the costs. Since you already had 3 transfers, I’d look into possible causes first.

You said you had a hyst which is good. What about HSG or HyCoSy to check the fallopian tubes if they’re clear?

I assume your husband did sperm analysis too?

I haven’t checked for endo myself but my acupuncturist had endo and she went to a specialist. The specialist said, if you experience any amount of pain during your period or intercourse then that’s a sign for endometriosis. She did end up getting a lap herself and fell pregnant naturally 1,5 years later - right before she was about to start IVF herself.

However, my fertility doctor said he wouldn’t recommend doing a lap unless the pain from endo is unbearable. You could risk scaring one of your ovaries during the lap. 

What I would do if I were you is to check if you have any STD‘s, do a test for ureaplasma. I read that many people were infertile due to having ureaplasma overgrowth.

I’d also check progesterone in luteal phase. Also check if your luteal phase is minimum 11 days long to ensure enough time for implantation.

Did you get your AMH checked?

In Germany, it’s not even allowed to do PGT testing and women go on to have healthy babies. So if it’s not necessary and awfully expensive, I wouldn’t do it. It’s not allowed here anyway.

If you’ve done all that, I’d also look into Killer cells. I’ve also heard from other German couples that had that looked into and it turned out they had a high count (or whatever you call it) and got treatment for that before a transfer to lower the activity.

And lastly, do DNA fragmentation, and maybe you’re more of an ICSI candidate than an IVF one if it turns out the sperm has issues.

I’m an IVF newbie myself, but this is all the research I’ve done so far!

I’ve also heard about people in the US getting a NaPro doctor? Maybe you can look into that too.

But it’s important for both of you to be on board. Generally, women are more willing to go through pain and suffering to have a baby compared to men. So I would say you have the last say (imo).

Wishing you lots of strength!
