4BC blastocyst not worth freezing?

[Greenfig123]

Wondered if anyone who has been in a similar situation can help?

I had two blastocysts this cycle from 3 eggs, which was a fantastic result. Today, Day 6, one has hatched and has been sent for pgta testing (which I’m obviously very pleased about) but the other is a 4BC.

Clinic says this 4BC is currently too low quality for freezing, and it will have to make 4BB over today or tomorrow. Currently it’s poor, with a small number of visible cells when the cells should be around 100, i’m told.

If more development happens, we will have a choice between just freezing or pushing to biopsy.

Likely, I will just have to take the clinic’s advice if it’s unsuitable for freezing. But at the same time, would be sad to lose any blastocyst (I have low AMH). Has anyone been in the same position and can offer any advice?

Thinking of you Hope you have people around you for support Still a small chance the blastocyst will grow stronger Sending good luck wishes and a hug

Take care of yourself

I'm not overly expert in what the gradings mean and if different clinics have different rules on what they will freeze, but just to send out some encouragement/positive vibes I'm currently 23 weeks pregnant with my frozen 4BC after 4 higher grade blasts failed to implant, so there's always a chance 😊 good luck ✨️✨️

Thanks and congratulations!!! Hope you are doing well.

The embryologist said that the grading systems do vary between clinics and a 4BC might be a 4BB elsewhere. Very frustrating as I thought 4BC didn’t sound that bad! They said it needs to get to 4BB- at least…

And this happens all the time !

Congratulations, I had done 2 transfer with AA and they didn’t work for us we thought they we’re the best we still have one AB so I hope so that one is the one

I literally just saw a lady in this page saying that she just had her son born from a 5bc embryo! One of my frozen embryos is a 3bc....

[Sarah770]

outrageous!!!! My baby no. 3 is a 3BC! Of course it is worth freezing!!!!! Absolutely do NOT discard, no matter what they say!!! The things we hear!!!!

[Twiglet2]

my son was a frozen 4BC!! Is it more than just the rating that makes it unsuitable for freezing? As that is a suitable grading for freezing and can defo make a baby! I would ask for more info before they discard it for sure xx

My 5 month old is a day 6 4bb or 4bc. Xx

My advice… Don’t discard the embryo. Grading system is not flawless and it is not exact science. It is frequently used by clinics that want to maximize their success numbers at the expense of embryos that might make it if given a chance. (Better success rate means more future clients and more money). With all that being said I am currently 39 weeks pregnant with an ungraded 5 days morula. So almost no chance of success but here we are. Of course things can still go wrong but that won’t be due to embryo quality. Good luck.

My clinic don’t freeze anything with a ‘C’ in, that’s their lab protocol. But I pushed back and I said I wanted them frozen and they froze 3 x 4BCs for me. All of them survived the thaw. Although none of the them worked (but probably a problem with me rather than the embryos after 7 transfers)

Can you have a fresh transfer? Just because an embryo isn't good enough quality to freeze doesn't mean it won't stick and become a healthy baby so if you have done the prep I would just go for a fresh transfer and if not, then I would ask them to freeze it and if they won't find out if there are any options such as clinics that will. Next time I would make sure that you insist they prep you for a fresh transfer in case you get blastocysts that can be transferred but might not be good enough quality to freeze and unfreeze again.

[Greenfig123]

Hi, unfortunately I haven’t been prepped for fresh transfer. I’ve been interested in a flexible approach preparing for both routes depending on the embryo/s I have, but my clinic makes me choose between fresh and frozen from the outset.

Being older at 43, we decided to freeze and test due to a relatively high risk of miscarriage if an embryo did take.
