It would not be the only method. In my anecdotal experience it seems like the stats did bear out better results (at least in DC). Yes there can be a lot of confounding factors like if the clinic only does IVF on unexplained infertility in people younger then 35 they will have a very high success rate as opposed to a clinic that does all comers. I guess, I think it pays to get as much info as possible-other infertile couples opinions, doctors opinions, IVF success stats etc. when making a decision on what clinic to go to. Most are good but there are definently some that are less good.I agree that facilities are not all the same. I just think IVF success rate stats are ineffective in distinguishing the good from the bad.Yes this can be true. However, if the numbers are complete butt you need to be leary that there lab sucks. Believe me all fertility clinics are not the same.Actually, these statistics are highly misleading and don't really say anything about the quality of the facility. The rates are heavily influenced by whether the doctors are willing to do IVF in less-than-ideal situations. Some places will refuse to treat women who are too old or have certain specified problems.Make sure you ask fertlity clinics what there IVF success rate is and then measure it against other clinics and the national average.
