It is bothering me that I've seen several comments here recently questioning Check's lab without any facts to back it up. It could be potentially very misleading to others considering Check. Sure there may be better labs out there, but I have found Check's lab to be quite good. I did have an unsuccessful IVF last July with Check but then had a successful IVF right after that and just gave birth in June. Egg/embryo quality are much more relevant.
