Sorry, lurking here - any update on your friend... was it a +ive.?

I have heard of FS quoting upto 50% success rates - but as others have said - it really depends on the individual, not just age and quality.

Even the poorest quality embryos can turn into take-home babies, just the same as top AA grade embryos fail to implant - there are no guarantees with IVF.

Hoping your friend got a positive though, especially after the FS getting her hopes up so high.
