Ivf. Does embryo grade sway gender?

[ChildOfTheMoon]

Just curious as I heard someone saying low grade embryos tend to be girls
Wondering how much truth there is to that

When I googled it, the information I found was based on our embryo grade. We got a 5AA back and it gave a 70% chance of it being a boy. I'm 13 weeks now and it looked like a boy at the last scan. We're getting our NIPT gender result back on Monday.
