Oh and NotSpartacus, I am very much a medical enigma, so I’m not sure the variation in my aneuploidy rate is terribly representative, as my hormones have been completely all over the shop beyond recognition.
I went from PCOS (fantastic ovarian reserve, brilliant FSH, AMH great) at 28, came off the pill to start TTC when I was 33, expecting to still have PCOS. My PCOS has gone, alone with all my eggs. In the space of 5 years my AMH has declined by 95%. My AFC is beyond pitiful. My FSH is horrific (17.6!), and it looks like I’m hurtling towards premature ovarian failure
On the basis of all investigations pointing to severely diminished ovarian reserve, we rushed to IVF very very quickly
We don’t know what happened for my hormones to have changed so drastically, but they did - and now, equally strangely, they seem to be returning to where there were before
ie I went from PCOS - DOR - PCO
First cycle I was def DOR. 7 eggs, 4 fert, all conked over after day 3 (ie all duds)
Second cycle I was DOR-ish - AMH of 1.5 but didn’t respond like a DOR person. 17 eggs, 12 fert, 5 blasts - one put back, and 4 frozen.
I got pregnant from the one that was put back, and subsequently miscarried at 10w - however tissue testing on the products of conception showed the foetus was chromosomally normal (ie the mc wasn’t due to embryo quality). And now that we’ve had the frosties tested, it turns out that one embryo was the only good one out of the five
The ovarian environment was likely still not brilliant, with hormones all over the place, and ongoing very low oestrogen issues. So, quantity wasn’t consistent with DOR, quality wasn’t consistent with my age.
Post pregnancy, we check my hormones and do a scan. Holy shit. My FSH is amazing. Actually, my bloods look like someone with PCOS cos the FSH:LH ratio is mental. So Dr says, hmm, let’s do a scan. Suddenly my ovaries are polycystic again. He says whatever the DOR was, it was some kind of blip, and we’re now seeing my true ovarian reserve again
Prev two cycles we’ve had to hit my ovaries over the head with the sledgehammer dose of stims. This time I’m on the mildest of mild doses. 10 months prior I had a total antral follicle count of 5. Now we’ve got 28 eggs. Which turned into 9 blasts suitable for biopsy and 6 of which were euploid.
So, the high abnormality rate in the 2nd cycle is likely to do with whatever craziness was going on with my hormones - esp my low oestrogen (oestrogen being very important for egg quality)
Third cycles my hormones were less all over the place, my oestrogen was decent, and the ovarian environment was healthier. So the aneuploidy rate was much more consistent with my age
My consultant said he’s been a fertility Dr since 1992 and I’m the most perplexing case he’s ever had. And he trained with Prof Robert Winston and knows his stuff
But thank god we did PGS. If we had gone through all 4 frosties and had multiple failed FET or more miscarriages I don’t think we’d have had the strength to carry on.
