Does age influence fertility treatments?

In vitro fertilisation

The rates for pregnancy with in vitro fertilisation depend on the patient’s age. We can see on this graph the rates for pregnancy by age groups after the transfer of fresh and frozen embryos from the same cycle.

 Egg donation

The rates for pregnancy with egg donation do not depend on the patient’s age. We can see on this graph the rates for pregnancy after the transfer of fresh and frozen embryos from the same cycle.
