IVF over 40: realistic odds and the smartest path

What the registries actually show, and when to switch to donor. This guide uses public registry data (SART/CDC, HFEA, ESHRE) and is written for international patients comparing countries.

Key points

• Judge clinics on live-birth per transfer, not pregnancy or per-cycle spin.
• Plan for 2–3 cycles — think cost per baby.
• Donor eggs reset success to ~48% at any age.
• Country law decides if you're even eligible.
