tomatotoes :  it’s typically a blood draw that can provide some pretty useful information in terms of explaining why things might be happening (maybe you’ve had recurrent miscarriages). Based on results it can influence best path forward to become pregnant, and can also guide you in terms of whether you might want to consider PGS testing if you do pursue IVF. 

There can be genetic reasons behind infertility (for example, maybe you have all pieces of your chromosomes, but two happen to be swtiched in a certain spot. you’d be fine, but when you go to make a new cell/baby, they don’t align properly with your husbands, so the cell will not be viable). In this case the doctors treatment of the interfertility diagnosis might be different than someone who has a different karyotpying result.

It can also tell you if you’re more at risk for having a child that will have a genetic condition based on whether you or your husband are carriers – if it is high risk, it may change your decision to pursue one route or another.

If you know for sure you won’t be doing IVF and will only be doing IUI, then the only value I see is having RE input on the chance of success. If IUI has a very small (or no) chance of working based on the results, at least you would know beforehand and can be mentally prepared. Or vice versa, maybe they find nothing at all and think there’s a high chance it will work. It would also let you know, if you do conceive, whether there’s any chance that child carries one of the commonly screened genetic conditions (like CFTR).
