So sorry for your losses op. I feel the struggle. I've lost 3, 2 rounds of IVF, 12yrs TTC and no actual cause for sub-fertility found. The only thing mentioned was 'old eggs'.
Have you read 'It starts with an egg'? I bought a copy off ebay. I thought it was worth a few, minor lifestyle changes to see if it helped. Changing from tinned tomatoes to cartons for example.
I started DH on a supplement of lycopene. Although his sperm analysis was borerline normal, I thought it cant hurt. Its found naturally in red/orange fruit and veg anyways, and some studies have shown an improvement in sperm count and motility.
I started on ubiquinol. I did a fair bit of reading, and apparently ubiquinol is more easily absorbed part of C0Q10 (or the active ingredient, I cant recall now). I bought NUYU brand, 200mg off ebay.,
Sorry if TMI. My 1st pregnancy had patau syndrome, discovered on NIPT, and the autopsy confirmed this. I sent the 2nd and 3rd miscarriages off for testing. The 3rd one, they did genetic testing which showed a different genetic issue- but again, likely due to older eggs.
If, sadly, you MC again, I would keep a sterile urine pot and collect the foetus for testing. Once again, sorry if this is TMI, but I found it reassuring' to know it wasn't molar, and also what that genetic issue was. Genetic testing isnt always possible though.
Happy to answer any questions you have ❤
