I was going to leave this as a comment to my last post, but it was getting too long. And this is my blog, so what the heck.
It occurs to me that clinics don't have a real incentive to have better success rates if women continue to support them. More failures = more cycles = more money for them. That's a cynical view, I know, but ever since I was pg with DS, I am much more cynical about the medical profession. I'd rather think success rates in different DE clinics is due to differences in donor pools, but when their protocols significantly vary from the best (e.g., Crinone vs. PIO), I have my doubts.
Also, DE Daddy's father was a doctor. The protocols are not propietary. So if clinics aren't using the best methods, it's not because they are not available to them.
Of course, after our failed frozen egg cycle, our RE did discuss a learning curve. So changes in protocol do incur a learning curve. Our first clinic had a real set back moving from thawing 3 day old embies to thawing 5 day old embies. But by the time they learned how to do it, their success rate for FETs nearly doubled and approaches the success rate for their fresh cycles.
To be honest, we would have stayed at our first clinic if they had not failed so miserably at the frozen egg cycle. But then we finally understood that you can use any clinic in the country, or the world for that matter, for your IVF or DE cycle. Your home clinic can do all the monitoring and the more successful clinic can do the procedure. All you have to do is get to the clinic in time for the man to make a deposit and the woman be available for the transfer. What's an extra $1000 in plane tickets and hotel rooms when you're talking about a $25,000 procedure?
I think that's the only way we can get all the clinics to step up their success rates.
