I wanted to share my story in case it gives a ray of hope to those suffering from recurrent implantation failure.
I am currently 14 weeks pregnant so still early days but it's a huge step forward for us. This is the result of the 11th embryo transferred (over 9 transfers as did a couple of double transfers), and prior to this we had always got negative results. Before this transfer I'd been thinking about giving up and looking at adoption but I'm so pleased I kept going.
A bit more of our story: we were initially treated in our local NHS clinic. We were both 34 when treatment started and although my husband's sperm was sub optimal, we were told we had unexplained infertility. We had one egg collection which resulted in 9 high quality day 5 and 6 embryos.
We had one fresh embryo transferred and then proceeded to transfer the remaining 8 frozen embryos. On two transfers we did double transfers.
Before our 6th transfer, we had NK cell testing done privately and found I had a slightly raised level. We therefore were prescribed steroids for the final two transfers but it didn't make a difference.
Once we'd used up all of our NHS embryos, we moved to a private clinic which we chose by looking at the rates of success of FETs for my age group.
The new clinic was very thorough and did so many tests. My AMH levels came back much lower than they had been for our first collection and so we were prescribed a pretty intense protocol for egg collection. Collection went pretty well and they used PIMSI to combat my husband's sub optimal sperm quality. We got 7 good blastocysts and after PGTA testing, 3 were said to be viable.
We then went through lots of more testing including repeated NK cell testing, ERA, Alice and Emma. Other than slightly raised NK cell counts everything was normal and the timing of the mock transfer was good.
I was prescribed steroids and intralipids to address the raised NK cell count.
Our first FET failed which was a massive blow. On the second transfer (which worked), they kept everything the same other than prescribing me buserilin in my prep and then they used an embryo glue and an HCG wash at the time of transfer.
Who knows what made the difference and whether the positive result would have happened regardless but I wanted to share this for anyone who is in the place I was before this most recent transfer.
Happy to share more details if helpful
