Looking for advice/research
Hello! 38, AMH .16, and AFC anywhere from 4-9. On my second round with a retrieval set for Tuesday. First round, we retrieved 6, 5 mature, 2 degenerated during fertilization, 2 out of 3 remaining fertilized and froze on day 3 because I go to CNY and they recommend freezing at day 3 if you have less than 4. This time, I’m looking at maybe 3-4 for retrieval. I consulted with one of the doctors at CNY and she highly recommended I push to blast. I’m leaning toward doing that, just nervous of course that we won’t end up with anything. So my question, is there really any research based advantage to freezing at day 3 over pushing to blast?
