Cumulative live birth rate
The chance of having a live birth after using all embryos from one egg collection, across a fresh transfer and any subsequent frozen transfers.
In plain English
It's your total chance of a baby from one round of egg collection, adding up the fresh transfer and any frozen ones that follow from the same batch of eggs.
Why it matters
It gives a fuller picture than a single fresh transfer's success rate, especially when several embryos are frozen for later use.
