ERA: The Test You Never Knew About

WHO THIS POST IS FOR:

  • IVF couples who have defied every statistic thrown their way despite her body doing everything its “supposed” to do.

————————————————————————-

Last week was a tough week to say the least. We learned Wednesday (after waiting two extra days in our 2WW— a whole other drag) that we are once again not pregnant. While I am no longer shocked by this news, this one stung a little harder because they used 2 perfect embryos (my $13,000 investment in PGD tells us this) and my lining was the thickest its ever been (around a 9.5). But despite the perfect conditions, once again the transfer failed.

LETS TALK STATS

As a 29 year old woman with no explanation for my infertility, I should have been pregnant well…. 2 years ago. But if we are going by science/stats, we are talking two transfers ago. I have now entered the zone where I am in the extreme minority of IVF parents. We know I have awesome embryos (7 out of 18 are genetically perfect) and my lining is being very cooperative. We can presume from the PGD test that its not an egg or sperm issue (although we can not say this definitively). I have had a  hysteroscopy to make sure my uterus was squeaky clean and HSNs periodically to make sure it remained polyp/scar tissue free. The only place left to examine is when my uterus is most likely to receive an embryo and now we are doing just that.

ERA TEST

I learned of the ERA (Endometrial Receptivity Array Test) test prior to our transfer when we talked potential outcomes with our doctor. He explained that 99.99999999% of women only need progesterone for 6 days before a transfer. For example if you have a transfer on a Thursday, you start your progesterone on Saturday night. The 6 day period gets your uterus to accept an embryo at the peak time for a transfer. However .0000001% (I made that up but its something like that) of women may need one or two or three days more of progesterone to give the embryo the perfect opportunity to find a new home. Thus, the next step for us is to examine if my uterus needs some extra time to bake.

WHY THE ERA TEST MAKES MY BLOOD BOIL

I know I post about this ALL of the time but I REALLY HATE BEING ON TRANSFER MEDS. I feel and look like shit. I am usually physically ill and always mentally exhausted. I wallow in a place of low self confidence when I am on meds and yearn to be off of them entirely or to be on them and pregnant (in which case I will suck it up and love each side effect).  I am a positive person and can put a rose-y  lens on most things but when I am on my meds I struggle to find the sunshine in the clouds. I have now spent over 150 days on these meds and the end is no where in sight.

In order to do the ERA test you have to do a mock transfer. Yup thats right, I have to go through an entire cycle of meds but do not get the opportunity to transfer. What this means is, once I get my period (it has arrived) I will start back on estrogen, I will go to the doctors twice a week, start on progesterone and go to the hospital for my “procedure.” However instead of having a transfer, they will scrape my uterus, grab a sample and send it to the lab to be biopsied. HURRAY! I will then have a 2WW for my test results (HURRRRRAYYYYY- can you feel the sarcasm oozing out of my pores) and then start back up on my meds for a transfer.

IS IT THE RIGHT TEST?

Of course only time will tell but from all of the literature Ive read, I am the prime candidate. My doctor did this test with a patient recently and she is pregnant. At this point in the game, that gives me little hope because each time I go through something new, I am told a story by someone that fits this framework.

“OH so many people have a successful transfer by the 2nd time.”

“Statistically most women are pregnant by the 3rd transfer, thats why insurance covers 4 retrievals.”

“This one patient couldn’t get pregnant but once she got her embryos tested she was successful her first time.”

The list goes on.

In a month or so we will once again be waiting patiently to find out test results. The highs will be high and the lows will be incredibly low. We are still on the worst rollercoaster that never seems to end.

**** I called my insurance to ask if its covered because I was told by doctor it wasn’t. (side note: Thankfully this is not near the cost of PGD). It is such a new and rare test that they had never heard of it (neither did the genetic counseling center that manages my referrals). I asked the doctor to submit it with a letter making the case as to why I need it. We shall see if they agree. If you are on the road to the ERA its worth calling your insurance directly to ask because your doctor may presume they won’t cover it which may not be the case.

  1. I’ve never heard about that test/biopsy. I wonder if its right for me. I was told by a gyno that I have scarring on my uterus. They asked if I ever had an abortion. I’ve never had an abortion or any procedure that would scar me. My infertility doctor didn’t seem concerned. I too had perfect embryos implanted, and got a BFN.

    1. The link I posted explains who a great candidate is. My doctor is a lead researcher for IVF and knows about the more obscure tests. If you have had a number of failed transfers you should definitely explore it!
