Implantation chances

Hi all - I just had my first embryo transfer yesterday, an euploid AA. I got pregnant naturally in Dec 2022 but miscarried. I asked my doctor who did the transfer what the % chance of a live pregnancy from that transfer, he put me at 25%. That seems a lot lower from what I have been able to gather online etc. He said it was lower because I am 41. I thought âge at the time of implantation had minimal impact, particularly when dealing with a genetically tested embryo. Would love to hear what you’ve heard! Thank you!
