Outcome definition
A positive pregnancy test, clinical pregnancy, ongoing pregnancy and live birth are different outcomes and should not be presented as interchangeable.
Outcome transparency
Success numbers need context
A percentage alone cannot tell you what may happen in your care. We explain what should sit behind any fertility outcome figure before it is used for comparison or decision-making.
Methodology and reporting context pending
Why we are not publishing a headline rate here
The current official source includes aggregate cycle-volume and success statements, but it does not provide the outcome definition, denominator, age bands, treatment mix, reporting period or cohort needed for a transparent comparison. Until those fields are published together, the figures are withheld from this staging page.
Read the number carefully
Six details that change what a result means
Denominator
A result may be calculated per started cycle, egg retrieval, embryo transfer or patient. The denominator changes the meaning of the percentage.
Age and individual circumstances
Age is one factor among ovarian reserve, sperm factors, diagnosis, prior treatment and other individual circumstances considered by the clinical team.
Treatment and patient mix
IVF, ICSI, frozen embryo transfer and other pathways should not be combined without explaining what is included.
Time period
Readers need to know when care occurred and whether the figure covers one cycle, cumulative treatment or a defined reporting period.
Fair comparison
Clinic or benchmark comparisons require equivalent definitions, populations and periods. Without them, a ranking or superiority claim is not reliable.
Questions about interpreting outcomes
This information is educational and does not predict an individual outcome. Discuss your circumstances and options with a clinician.
Start with your questions, not a headline percentage
A clinician can explain the factors relevant to your circumstances without guaranteeing an outcome.
