I appreciate that you only publish data on clinical, rather than chemical pregnancy rates, which is a much more accurate view. But can you give a broad indication on the delta between clinical pregnancy and live birth rates, when using donor eggs, in the over-40s (recipient) age bracket please? Is there a significant difference?

Clinicla pregnancy rates are those with a heartbeat and are usually at 7-8 weeks. To provide an indication age 40-45 years is 34% and 46-50 years is 25% (both using donor eggs). The pregnancy loss rate after 8 weeks is low, misscarriage rates are 2-5%, so this would give a live birth rate of 30% (40-45 years of age) or 20% (46-50 years of age).
