Comparison dashboard
The easiest mistake when comparing IVF success rates and costs across countries is putting figures with different methodologies side by side. Every entry shown here is labelled with its source, sample size, methodology, confidence interval and data year — understand the methodology first, then the numbers.
Data inclusion criteria
These five gates must be passed before any entry goes up. If an entry falls short, we would rather leave it empty.
- A source is required, and clickable
- Every success-rate entry carries a source link, labelled with the source's domain (e.g. www.sart.org). Data without a source is not entered.
- Sample size, methodology and confidence interval, all three
- The SART floor. Data missing any one of them is visible on the institution page (flagged) but does not enter the dashboard.
- Different methodologies, separate tables
- Per egg-retrieval, per transfer, per treatment and per thaw cycles are four different denominators. Figures from different methodologies live in different tables; you will never see them in one column.
- Derived values must declare themselves
- Figures the source did not state directly, converted by us, are labelled with the derivation method and cross-check source (recorded in
is_derived/derive_note) - Data year and age in days
- Success-rate data lags by nature (the newest verified data in 2026 is still from earlier years), so every entry is labelled with its year and its age in days — you judge how much to trust it.
