    Arrow Links: embryo & blastocyst grading explained

    I just came across these web pages and thought others might find them as useful as I have.

    Embryo grading system
    : There doesn't appear to be any standard grading system for embryos -- One clinic might grade on a scale of 1-4 with 1 being the best, while another might grade 1-5 with 5 being the best and so on -- but this page explains the different aspects of the embryo that are looked at when assigning a score.

    Blastocyst grading system: This page explains the most commonly used blastocyst grading system and what the numbers and letters refer to. (5AA, 3AB etc.) Full of great info, easy to understand.

    Happy reading!

    Hi Kim thanks for the link nice to see you are in Melb I am out Essendon way. good luck for your growing embies.
    Just wondering my clinic didn't give me any grading just said that the cells were a perfect formation. Are they supposed to give a grading.

    Hi rainbow,

    Some clinics say they don't grade their embryos. I'm with CFC, and I've never been given a grade on my 2 or 3 day transfers (though I haven't asked) -- I've just been told the number of cells and how much fragmentation there is. My first instinct is to ask about a grade next time, because I was always that annoying teacher's pet at school and liked to be at the top of the class ... but I think in general I'd rather not know if I don't have a top-shelf embie going in. The 2WW has enough anxiety without worrying that you're starting off behind the mark, on top of everything else. That's just me, though. A lot of women like to know.

    for your BT this week!

    I am with CFC too - just out of interest have you done any research on the ET without using U/S. We visited another specialist who suggested that ET wout transfer is flying blind. Funny about the teachers pet comment I am the same - knowledge is power
    BTW I got my period this morning so not my month - maybe next month..... Rainbow.

    I haven't done any research into it ... my FS seems to find the right spot without it.

    That's a good question actually, I've heard a bit both ways, makes me nervous! There doesn't seem to be a standard. Each clinic seems to have their own way Wish it was easier for people not doing the procedures to understand, and make a better choice based on that.

    There is an international consensus statement on embryo grading. If your clinic doesn't use it, get them to explain how what they use relates to this.

    http://humrep.oxfordjournals.org/con...ep.der037.full

    One of the problems is that embryo grading/quality does not really correlate with pregnancy at all.

    Yes, buffy is right. Embryo grading is only useful for the enbryologists to choose the best ones from the batch youve got, i.e. it helps with the selection process. So it can tell which ones might be better than others. It doesnt confirm whether the embryos actually are any good or will work.
