Yesterday, I had a Day 5 transfer of one early blastocyst. We used an egg lot of 7 from DEB USA and my husband's sperm. Of those 7, 5 fertilized, on day 3, we had 2 good embryos, 1 fair, and 2 poor, and only two made it to early blastocyst stage on day 5. We learned today (day 6) that none of the remaining embryos (including the early blastocyst that was not transferred) stopped developing. Does that sound normal for a donor in her early 20's? Are there any implications for the early blastocyst that we did transfer (or are the odds of success with that one completely independent of the others)? What is the success rate with day 5 early blastocyst transfers?
