Donor eggs vs own eggs — by age

The single most important chart in IVF after 40: own-egg success collapses with age, while donor eggs stay ~48% at any age (ESHRE 2019).

Donor eggs ≈ 48% at every age. So at 35 own eggs (~41%) are close; by 43 (~8%) donor eggs are ~6× more likely per transfer — and usually cheaper per baby.

What it means for cost per baby

At 43, ~8% success means ~4 cycles for a baby; donor eggs at ~48% mean ~2. Even at a higher per-cycle price, donor eggs win on cost per baby for most women over 40.
