Hi Oonagh,
Sorry to read that you have been trying for so long with no success. We have not tried DIUI as my DH is currently dead-set against using donor sperm.
I used Humira and IVIG but with a ICSI and a FET cycle.
It's really difficult as the immune angle makes things so expensive and so complicated and on top of that there is MF or other causes. Sending lots of sympathy to you as this is all so hard and unfair.
Wishing you all the best.
With warmest regards,
