Hatching blast

Hello, just wondering do all blastacysts hatch? Even low grades? I had a 5BC transferred and it has started to hatch a little before being transferred, wondering if this is a good sign?

Hi Tilly, hatching is def a good sign. Best of luck!

All blasts have to hatch 🐣 in order to attach and implant. Think they have to be transferred prior to day 6 as the onward process needs to happen in the uterus. If it's only started to hatch I would think that would be fine as there is a process called assisted hatching which you can pay for prior to transfer, as some blasts struggle to hatch. I'd take the initiation of hatching as a good sign that things are working well and it could attach soon after transfer. All the best 💖🤰

Hiya, it had literally started to hatch as we were waiting for it to be implanted, our transfer was delayed a few hours as the hospital was behind with transfers. I’ve never had a hatching one before but it’s a 5BC so not the best grade x

I'm glad you asked this question as it's the same as me ,so it's interesting to listen to people ,is what I'm not sure of is does it need to fully hatch to form a pregnancy or can it still happen if it only just begun to hatch x

The wait is a nightmare only 3 days and have cramps so jump to assuming the worse need to stop thinking about it! When’s your test day? Its numerical not alphabetical at my clinic we had 5 day 1:1.

Here's some positive research in relation to grade 5 (hatching) blastocysts:

Transfer of spontaneously hatching or hatched blastocyst yields better pregnancy rates than expanded blastocyst transfer

Extending culture of expanded blastocysts by a few hours to allow transfer of spontaneously hatching/hatched blastocysts gives higher implantation and pregnancy rates with no added risk of multiple gestations. Spontaneously hatching/hatched blastocysts have a better potential to implant and develop into a positive pregnancy.

Let’s hope this gives me a positive result. It must mean it’s still growing, the only thing is the hospital don’t do pgs testing so no idea if it is abnormal or normal. X
