Rubbish eggs at 35? PGTA and implantation failure

[Zest11]

Hi,

I have a history of implantation failure/early miscarriage from IVF. I have 1 live birth and he is healthy. I wondered if my history indicates poor egg quality or is it sperm or both? I don't need anyone to be gentle...bluntness is welcome. At my age I thought to expect 60-65% euploid...

Age 30: AMH 11. Not sure on sperm but well within normal.
Age 31: EC 5 blastocysts from 10 eggs. (Fert: 8) 1 live birth. 3 of the other blastocysts were implantation failure, 1 early m/c.
Age 35: AMH 3.5 Sperm morphology down to 4% but all other parameters good. Sperm DNA frag 8% so normal.
EC: 3 blastocysts from 9 eggs (7 fert). 1 fail, 1 chemical. 1 still in storage.
Age 36: Amh untested. Morphology 2% but all other parameters good. EC: 5 blastocysts PGTA tested from 13 eggs (11 fert). 4 abnormal, 1 normal (the most poorly graded and day 6). Yet to transfer or request a follow up.

We have had 6 failed transfers in total (I appreciate 1 live birth!), 5 of which were for a sibling. 2 ECs we're not tested but the last one was.

@Zest11 hi I hope you are doing as well as can be expected in this journey. I have had two transfers both failed. I'm 34 years old. AMH 17.9 when it was tested at 32 years. My partners morphology was 2% first time and then all his parameters were borderline the second test. (I think he's still clueless as how they class that as MFI) every other test I've had its all been normal. And now we are soon to go into 3rd transfer and I'm so scared. Can I ask what you did different in your single successful transfer which resulted in a positive x
