About My Embryos

Thanks everyone for all the birthday wishes.  I had a low key but pretty nice birthday.  To celebrate, Babe and I went out to dinner at a fancy restaurant that provided complimentary wine and dessert.  He kept telling me he didn't know what to do for my big 40th, nor what to get me for a birthday gift.  In the end he ended up getting me what I wanted exactly, a Kin.dle Paper.white.  And I was just about ready to order it myself from Ama.zon!  Not only that, that stealthy hubby of mine managed to throw a SURPRISE birthday party with the family at the park near my house the day after my birthday.  Sneaky little bugger!  In the end, I had a pretty awesome 40th birthday.  Don't forget to sign up for my birthday giveaway if you have not already done so.  Tomorrow, Sunday is the last day to sign up.

Last Friday, I emailed Carol, the embryologist at NEDC and found a few more things about the embryos we adopted.

Carol was able to tell us the quality of our embryos when they were cryopreserved.  However, that does not mean that they will be the same quality when thawed and culture to transfer.  The embryos will be re-graded after the thaw.   We will be presented with pictures and their new grades at the time of transfer.

This was Carol's explanation of the embryos to me:
  • For blastocysts (which is what we adopted), the embryos are normally graded with a number and two letters.   
  • The number is how expanded the embryo was at the time of cryopreservation and really does not have anything to do with the quality.  Excellent embryos can be anywhere from 2-6, with a fully expanded embryo being a 5, and a hatched embryo being a 6.  
  • The first letter is the intercell mass which becomes the baby, and excellent quality are A & B, and then the letter goes down from there (C, D, etc.)
  • The second letter is the trophectoderm which becomes the placenta and again A & B are excellent quality.
  • From our first donor, the five embryos are graded at 3AA, 3AA, 3AA, 6AA and 4AA (all excellent quality embryos according to the embryologist).  The embryos are frozen in three vials - 2 vials with 2 embryos each, and one vial with one embryo.
  • From our second donor, all three embryos are graded at 4AA (again all excellent quality embryos according to the embryologist).  The embryos are frozen individually, one embryo per straw.
Because our embryos are all at the blastocyst stage, we will not need to do assisted hatching, which would have cost us an additional $525.  Also, all our embryos are already at NEDC so we do not need to pay any additional cost for shipping.  Yay!


  1. Be prepared for the donor costs that are due the day of transfer. Usually the reimbursement for storage and shipping. Ours was around $250 I think. Not sure if u have heard this or not or if your donors have no fees. :) getting close

  2. so glad your embryos all have such great gradings!!!

  3. I saw your blog on the list for ICLW and wanted to follow. We had talked a lot about embryo adoption. Its still an option in my opinion if future ivf doesn't work or if I don't get to do a future ivf. I think its a really awesome choice and such a miracle to be able to still the baby(s)!!! I'm so excited for you and the embabies you've adopted sound wonderful! :)

  4. Great news-I can't wait to hear your transfer details and beta number! September will be here soon. :)

  5. Yay! I agree with Kim, if you haven't already, ask about any attached fees that the embryos may have. I am glad a past NEDCer told us to ask!

  6. Awesome grading news! It won't be long now!

  7. YAY for the no extra fees!!! Thinking of you guys! :)

  8. Did nedc get back to you on fees associated with your embies? Have not seen a post for a couple of days and was just thinking about you. Luckily you dont have to pay assisted hatching so that should cover it!!

  9. That's awesome! Embryo adoption is definitely new territory for me. Interesting to read about how it works!
