Birth rates as a percentage of transfer, from fresh donated eggs

This graph shows the delivery rates per transfer in an IVF cycle with ovodonation, using fresh donor eggs.

Since these are donated eggs, the age of the recipient woman does not affect the success rate of the treatment as much. For example, the delivery rate in women under 35 years of age is 46.8%, while in women over 40 years of age it is 43.5%. As can be seen, the percentages are similar. These data have been collected from the latest statistical registry of the Spanish Fertility Society corresponding to the year 2021.
