Day 5 transfer

[Jenny_]

I had 12 fertilised eggs on day 3, but today, when I went to hospital for day 5 transfer, only 1 of them managed to develop into a blastocyst. I was quite surprised as usually 30% could grow into blastocyst.

Now, the questions are:

1. Are ICSI embryos less likely to become blastocyst?

2. If an embryo couldn’t become blastocyst in the culture, would it more likely to survive in the body?

Hiya jenny

I had normal IVF may last year and 4 made it to blasto. 1 put back but none to freeze.

I had ICSI last November. Out of the 12 fertilised 5 made it to blasto. 1 put back and 4 to freeze. so dont think its the icsi.

I did make a few changes to my lifestyle to improve egg quality too but nothing major xx

That’s good to hear. Thank you.

When I heard that 11 embryos died at the blastocyst stage, I really regretted that ICSI choice. Now, I feel much better.

ICSI is the preferred technique for most embryologists. 'Cause of the number of advantages that if offers in comparison with classical IVF. However, there exist a series of factors that can affect the outcomes of ICSI, I mean egg quality, sperms morphology etc. It's not necessarily the procedure itself.

If an embryo couldn’t become blastocyst in the culture, would it more likely to survive in the body?--Many embriologists prefer transferring 3 day embies to give them the chance to be harvested further, though not of the best quality. So probably this makes sense as well. Stay well, hun, this is a tricky game.

Thank you. Your comments are really valuable for me. I will probably do day 3 in the future if this cycle fails.
