Mobaby and oneof14 - My clinic preffers to transfer blasts so that is why they are not doing fresh. They can't do the fresh transfer on day 7 b\c the embryo's will be out of sync with my body at that point (thansk to DaisyQ for explaining this all to me!) Many clincs do transfers before blast and plenty of women get pregnant. I guess they grow to blasts inside you and then implant. I don't know if they implant before becoming blasts or not
Mrs. C - our lab closes twice a year, once in the summer and again around Christmas, so that it may be cleaned. I think those embryologists just need a well deserved vacay! This only impacts IVFers, not people doing IUI.
Blue, to answer your question, an embie must make it to blast to implant. Successful IVF cycles where day 2 or 3 embies, or day 5 morulas are transferred - those embies continued to develop in utero to blast, and then implanted. You are right - our clinic likes to do only blast transfers. They have very high success rates, and so this is what they thinks works best. That's why they will continue to grow out your embies until blast. And like you said, by the time your embies are blasts, your uterus will no longer be receptive. So it's best to wait, and do the FET. The FET success rates are stellar. DON'T worry. Are you doing CCS/PGD?
Thanks for explaining that. They do deserve a vacation! A good cleaning is also a good thing.
Got the call from my nurse. My E2 levels have not yet risen, it's right around 65. I'm to increase my follistim/gonal F from 300 units to 375 units, and my low dose Hcg from 15 units to 30 units. Yikes. Hope something starts to happen - and of course that it happens to ALL the follicles equally and at the same time.
Fx for you!
