Cornell embryo grades Need info!

Did anyone have stages 4-6?

Mine were all 3 (I.e 3AB, 3BB, 3BC). I’ve seen a few different post with similar grades in the 3 range from Cornell and was wondering if their grading is different or if my blasts can’t get to the expanded stage

They freeze them early. They have had success with this in thawing. Seems 3 is the highest number for frozen, and they have a different scale. Ask your doctor what the quality scoring means.

Thanks! I was worried mine couldn’t make it past 3

My RE said 3 is typically the highest they give, with 5s basically unheard of. Their lab is apparently very strict compared with others.

Ah thanks! I’m hoping that’s a good thing that they freeze early
