We paid privately and went to the London's women clinic (then the Cromwell) in Swansea.
Excellent excellent service - we only chose to go there as we'd been waiting for two years on the NHS, and all they had offered us was clomid - which was useless as it was a male factor fertility issue, not a female one
We had five lots of IUI, the first two ended in miscarraige, the third was abandoned due to lack of stimulation, the fourth falied and the fifth i got pregnant with triplets - which resultewd in my now healthy five year old son.
We also went on to have a course of IVF, doing an egg share, in the hope of a sibling for ds, but that wasn't meant to be, and failed.
All in all, i can't fault the treatment we had from them. They always took the time to explain things. Yes, we were paying them to, but that shouldn' make a difference.
