Hi Sararms,

Which clinics are you referring to? Sorry, I donk know where Berks is to work it out.

You want to be careful when comparing "success rates" between clinics. One clinic may have a differnet definition of success to the other. Make sure that you have all the facts. Although we all have the notion that IVF will be the miracle cure, it sometimes takes a couple of goes for the Drs to get the "mix" right so to speak. Before changing clinics I would have a word with your current clinic to find out what they think happened and your options. Then at least you can take that knowledge to your next clinic if that's what you decide to do.

There have been other threads where the pros and cons of blasts have been discussed - I'm not clever enough to put in a link, but if you have a look back through the old pages on LTTTC you'll come across it.

Hope that helps
