Success rates

The success rates of IVF in Australia are usually expressed as "clinical pregnancies" per embryo transfer procedure.

In a clinical pregnancy, a pregnancy sac may be seen on an ultrasound 4 weeks after the egg collection procedure, but a heartbeat may or may not be seen. A significant number of these pregnancies will miscarry. If there is a heartbeat, then the chance of miscarriage is less than 5%, so the "heartbeat positive" pregnancy rate takes us further.

Our most recent clinical and heartbeat positive pregnancies categorised by age are shown in the graph below. These data exclude egg donation cycles.
