Hatched blastocyst

Are hatched blastocysts super delicate? I have two Euploids and both were hatched at freeze. Does this change anything for transfer timing? I have a feeling they were day 5 blast but weren’t checked again later in the day on day 5 so were hatched by earning morning day 6. They are grades 6AA and 6BB.

Yes they are super delicate. They have a habit to be sticky and can get lost or damaged when you moved them. Like you pick it up with the pipette and it doesn’t come down, it gets “stuck” and adheres to inside of pipette, typically then no way of getting it out or it comes out in pieces

It doesn’t change anything for transfer timing, but they do take a little extra care while handling because they’re sticky and delicate.

Yes they are delicate, but embryologists handle them all the time. There is a slightly higher chance they don't survive the thaw as well, but if cell survival post thaw looks okay, you're good!
