Hi, just looking for a bit of advice/guidance as I've not really been able to find any statistics on this. I have 5 frozen blastocysts from an IVF cycle 3 years ago. I was 31 years old at the time and the fresh cycle resulted in twins, with the remaining embryos being frozen. I'm still undecided about whether I want a third child, and have been wondering if I would be decreasing my chances of success the longer I leave it, or do my chances stay fairly the same?
I know egg recipients are told that their chances of a successful pregnancy are good as the egg donors will be under 35. I'm just wondering what kind of issues I might develop/encounter as I get older in terms of implantation/carrying a pregnancy? Are the higher rates of miscarriage for older women linked to egg quality, or are other issues involved?
