I do agree that some unscrupulous places are probably out to grab as much money as possible, but i honestly don't think coventry is one of them. It is nhs self funded (the cost covers the cost of their research), and there have been a high number of positive results on the rmc board under their treatment. Although they haven't done a large scale trial yet, a scoping trial showed an increased rate of pregnancy success from 40% without treatment to 60% with treatment, which to me represents a improvement that is worth taking a chance on. Less than 10% of people tested for uNK cells at Coventry are found to have high levels, so the testing is much more stringent than blood nk testing, where i have noticed a large number of people tested show high results (perhaps they are the correct ones, but I prefer the idea of the testing being more stringent so the treatment isn't given potentially unnecessarily)
My nhs consultant is also very sceptical of Coventry and their treatment. She is the 'top' (one of two) rmc consultant in Edinburgh. She doesn't trust it because it's not in the nice guidelines. Rmc is not the only job she does. She is also a consulting gynae on the labour ward. The bottom line is, she doesn't have any interest in complicating her life by following other people's treatment plans that haven't yet gone through rigorous testing. It's easier to just say it won't work and hope the patient goes away.
Unfortunately for us, this mistrust between rmc specialists of anyone else's research In their field seems to be a common feature and imo is inhibiting understanding, as everyone refuses to believe other theories. Coventry are equally sceptical/ scathing of the immunes theories (mr shehata et al), yet people spend absolute fortunes on these treatments, many successfully.
I think everyone needs to do their own research and decide how far they go. For me, Coventry was a last resort and it turned out to have an answer for me. If this pg fails on treatment then i really don't know where that leaves me, but at least I've tried coventry.
