Published success rates
The measures YourIVFSuccess publishes for No. 1 Fertility, each with the prediction range and the national figure for the same age band and measure. Treatment years differ by measure and are shown against each.
Before comparing these figures
YourIVFSuccess states: “It is very important that you do not choose a clinic based only on success rates. It is difficult to compare clinic success rates fairly, as these vary greatly depending on the types of patients a clinic treats and a clinic’s individual treatment strategy.”
- A prediction range that overlaps the national figure means the difference is not distinguishable from chance. Most Australian clinics overlap on most measures.
- No success rates are reported for women over 42, due to the small number of cycles in that age group.
- These rates describe the clinic’s reported patient mix, not your own chance of a birth. Clinics treating different case mixes are not directly comparable.
