OP I'm so very sorry for your losses
Regarding your question, I assume you mean PGS rather than PGD
PGS is pre implantation genetic screening, and checks whether the embryo has the right amount of chromosomes to become a person
PGD is pre implantation genetic diagnosis, which screens the embryo for specific inherited genetic diseases. It doesn't assess whether the embryo is chromosomally normal, just whether it is affected by the genetic disease in question
I had PGS - it is simply an embryo selection tool. It doesn't improve embryo quality - all it does is enable you to identify which embryos (if any) are euploid for transfer
Damaging the embryo shouldn't be a risk in a decent lab with an experienced genetics programme
Older techniques like array CGH are less accurate at detecting mosaicism so may incorrectly assess embryos as being aneuploid when they are in fact chromosomally normal
Next generation sequencing (NGS) is the newest PGS technique and is significantly more accurate
However it cannot improve the quality of embryos
It's only really worth doing if you have a lot of embryos and want to identify the good one (s)
To be blunt, at 44 the chances of a euploid embryo are about 2%
www.advancedfertility.com/age.htm
It is highly likely that to get a euploid embryo you would need to bank a decent number of blastocysts over multiple cycles to have enough embryos to make PGS worthwhile - and even then it's very possible to have no normal embryos
At age 34 I had 50% aneuploidy of my embryos - that's about normal. By age 40 that increases dramatically. By 44 it's over 95%
As we age the mitochondrial energy of the egg declines, which is another contributing factor to embryo competence. A euploid embryo of a 30 year old has more chance of becoming a baby than a euploid embryo of a 40 year old because the younger egg is likely to have greater mitochondrial energy to support successful embryo development
The cost of IVF with PGS depends on the number of rounds and the level of stimulation drugs
PGS requires all embryos to be frozen while the biopsies are tested and if there are any normal embryos, to be transferred in a subsequent frozen cycle
My first round of IVF cost around £2000 for drugs and £5000 for the IVF+blastocyst culture (£6000 for ICSI) but all the embryos arrested after day 3 and there was nothing to transfer
My second round cost £2000 for meds plus £5000 for IVF. Transferred one without testing - miscarried but was chromosomally normal. Had paid £1000 to freeze our remaining 4 blastocysts without PGS.
We paid £3000 to PGS test our already frozen embryos and all 4 were abnormal. I was 34 at the time of making those embryos.
Third round was £2000 for meds plus £5000 for IVF plus £3000 for PGS plus £1000 for embryo freezing
This time we got 9 blasts and 6 were euploid
The cost of a FET was a further £2000 including immunes meds.
I also miscarried this embryo
PGS is very very expensive and can only identify a good embryo. It can't create a good embryo
As you can see from the graphic, unfortunately the chances of a live birth at age 44 are very small indeed
Donor eggs are a very very difficult step to make emotionally and wouldn't be for everyone. It isn't a step to be taken lightly and would require a serious amount of implications counselling. But it would be worth considering as an option alongside IVF with PGS, because the chances of success are so much higher at the age of 44.
It's not impossible but very very unlikely.
Wishing you the very best of luck whichever path you opt for
