My first DE cycle was with a 26 y/o proven donor that had four previous cycles resulting in three singleton births and one twin birth. She also had a child of her own. We got a negative on fresh cycle, BFP that ended on m/c at six weeks, and embryos that did not survive thawing. Our second cycle we picked a first time donor, 23 y/o that has no children. We are now 13 weeks pregnant from fresh blastocyst transfer. Although our clinic would not give us the actual numbers they did tell us her day three testing was excellent. Because we were in a guarantee program and knew we could get add'l cycles at no cost if it didn't work we were willing to take the chance on unproven because we liked everything else about her. GL!
