Hi lalitearns,

For me after 4 transfers with never a hint of a BFP, I pressed my FS for these tests. I have heard that some FSs won't ask for these tests until up to 8 unsuccessful transfers. I think all my BTs cost approx $400, most I claimed back from Medicare


Hi everyone else,

I also wanted to post that my new FS gave me the results from an extra BT she requested. My last FS had requested a whole range of tests, see my earlier post in this thread, but had missed MTHFR for some reason, not sure if this was not requested just because of an error.

Anyway, lucky for me my new FS picked up that it was missing and my results showed positive for MTHFR. In the weirdest way I am over the moon as now I have something that could be contributing to my unexplained infertility.

From what I understand people with MTHFR factor don't produce folic acid, vitamin B6 and vitamin B12. Women with MTHFR factor can have early miscarriages and a lack of B6 and B12 directly affects rapidly reproducing cells... which is exactly what an embryo is. In fact, a lack of B6 and B12 causes rapidly reproducing cells to STOP reproducing. This is also linked to an increase in homocyctein levels and falls under the thrombophillia blood clotting disorder.

Some I am now on:
Low dose aspirin daily (100mg)
5mg folate daily
Mega dose of B6 and B12
Clexane injections daily from ET

I am yet to know if this will make the difference to me getting a BFP, will definitely post my results, but just wanted to stress how worth it it is to get all your tests done and make sure ALL of them are done. I don't want to think about what it would have meant if I didn't get this one result, (everything else tested normal), possibly endless more transfers.

Best of luck
