pesky I'm a bit (lot!) of an odd one as my ovarian reserve changed a lot in a short space of time
I had one at 28 which showed I had spectacular ovarian reserve, but was the means by which my PCOS was diagnosed - so I was aware before TTC that I would have a fertility issue of some sort - I just didn't rush to start TTC earlier because the tests showed my biological clock was looking good
Aged 33 we decide to start TTC - anticipating that we are likely to need some treatment because of the issue identified 5 years previously. I ovulate my first month off the pill - which would have been great news for anyone else, but for me was a warning sign something seemed to have changed (given I was expecting to still be PCOS)
Went for another fertility mot straight away and discovered my ovarian reserve had absolutely plummeted beyond all belief
Now, low ovarian reserve doesn't mean you can't conceive naturally IF all the other bits of the building blocks are in place. It's just a measure of quantity, and in a natural cycle you're just ovulating one egg a month - which is where quality, not quantity, counts . But it does mean the clock is ticking much much faster
A couple of monitoring cycles and more tests with a private gynae showed that yes, my ovarian reserve situation looked pretty dire, and also that I had persistent thin lining issues that meant although I was ovulating, had patent tubes, DH swimmers were fine, as nothing could implant, I'd need monitoring cycles with lining support if we decided to TTC naturally
We didn't want to take the risk of getting a year down the line having not conceived and our chances of IVF having been significantly less then they would have been a year prior - given how fast my ovarian reserve was depleting
The tests for me showed two things
- it can lull you into a false sense of security
- but the second one when we decided we were ready to start TTC meant we found out earlier rather than even later that things had changed so drastically
We didn't have quantity on my side, but we did have quality - which is primarily determined by age. My consultant said even if we didn't get many eggs, the fact I had age on my side meant we had a better chance of there being a good one in there. He said if I'd been 5 years older with the same ovarian reserve - ie aged 38 rather than 33 - the picture would likely have been very different
We conceived on our second IVF cycle, aged 34. Sadly I miscarried at 10w, however the tissue testing showed the miscarriage wasn't due to chromosomal abnormalities - ie it wasn't due to embryo quality, and I did indeed have some good eggs left
We're going again, and hopeful that if I had one good egg, I'll hopefully have another
Very long-winded story, and mine is NOT a representative example - ovarian reserve doesn't normally decline so drastically between 28 and 33! But being proactive did identify a number of issues earlier on.
