The EU median gives each reporting EU-27 country equal weight. It is the middle country result, rather than a pooled patient success rate. Each treatment uses its own denominator.

Own eggs · partner sperm
These national results use their registry’s age bands, years, treatment groups and outcome definitions. The EU reference uses different definitions, so a direct difference is not calculated.
Source: HFEA · national dashboard
About these statistics
HFEA national dashboard, 2023 only. The three selections use donor eggs / partner sperm (all cycle types), patient eggs / partner sperm with frozen ICSI, and patient eggs / partner sperm with fresh ICSI. Native HFEA age bands are retained. For own eggs the dashboard uses age at egg collection or transfer if collection age is missing; donor cycles use recipient age at treatment. Rates use embryos transferred as the denominator, rather than transfer cycles. Dashboard values are rounded and small values/rates can be suppressed. Displayed rates are read from the pregnancy-rate card after setting each age, treatment, egg/sperm source and year filter. They are not directly comparable with the EU 2020 benchmark.

Own eggs · fresh ICSI · first-transfer outcome
The result covers the first fresh transfer following the collection, rather than all future frozen transfers.
These national results use their registry’s age bands, years, treatment groups and outcome definitions. The EU reference uses different definitions, so a direct difference is not calculated.
Source: SART · national member-clinic report
About these statistics
SART covers its reporting member clinics. Own-egg results retain the source age bands and first-transfer cohorts. Fresh ICSI includes ICSI and excludes frozen eggs, frozen embryos and gestational carriers. Frozen results include only first frozen embryo transfers, excluding frozen eggs and gestational carriers. PGT is included. Donor results are live births per recipient start or thaw across all recipient ages, rather than clinical pregnancy rates. None of these rows is matched to the EU 2020 age benchmark.

Own eggs · fresh IVF and ICSI combined
These national results use their registry’s age bands, years, treatment groups and outcome definitions. The EU reference uses different definitions, so a direct difference is not calculated.
Source: CFAS / CARTR Plus · BORN Ontario
About these statistics
The 2025 CARTR Plus annual report covers 36 reporting Canadian clinics for 2024 treatment and pregnancy data. Its ongoing pregnancy endpoint requires at least one fetal heartbeat on ultrasound. Own-egg ages refer to the oocyte provider. The fresh series combines IVF and ICSI. Frozen own-egg results here exclude PGT-A. Donor results pool 2013–2023 across all recipient ages and exclude gestational carriers. The source numerator and denominator are used to calculate each displayed rate. These series do not match the EU 2020 clinical-pregnancy definitions and age bands.
Use the numbers for a better clinic conversation
Match the treatment
Compare the same age, egg source and treatment stage. A rate per transfer describes a different group from a rate per egg collection or thaw.
Read the outcome
The European tables measure clinical pregnancies. UK uses pregnancies per embryo; US donor data uses live births; Canada uses pregnancies with a heartbeat.
Put national results in context
Patient populations, treatment choices, reporting coverage and follow-up vary. National results help frame questions for a clinic; they do not predict your personal outcome.
Sources, age groups and EU benchmark method
The European comparison uses the published ESHRE/EIM 2020 country rates: S12 for donor eggs per transfer, S11 for own-egg frozen treatment per thawing cycle, and S10 for fresh ICSI per egg collection. Countries appear when at least one age-specific rate is published for the selected treatment. Missing values remain “Not published”, rather than zero.
Age labels follow the source exactly: <34, 35–39 and 40+. The source does not clarify the boundary for age 34. Donor age is recipient age; donor treatment variants are combined. These tables do not provide age-specific cohort sizes. The 2020 treatment year was affected by the pandemic.
EU reference values are unweighted medians of available EU-27 country rates, separately for each treatment and age. Donor eggs: 16 countries; frozen: 18; fresh ICSI: 19. Non-EU countries are shown in the shared registry comparison when available but do not contribute to the EU median.
UK HFEA 2023 uses its native ages and rates per embryo transferred, with own eggs and partner sperm for fresh/frozen ICSI and donor eggs with partner sperm for the donor table. Rounded source precision and suppressed results are preserved. US SART 2023 covers reporting member clinics, uses first-transfer cohorts for own eggs and live births per recipient start/thaw for donors. Canada CARTR Plus reports 2024 own-egg results and pooled 2013–2023 donor results; fresh IVF/ICSI is combined and the displayed own-egg frozen series excludes PGT-A.
US and Canadian donor tables group all recipient ages by treatment type. Their overall donor results are not repeated as age-specific rates. The three national sources retain their own definitions and are not numerically ranked against the European reference.

Questions to ask your clinic
- What are your clinical pregnancy and birth outcomes for patients of my age using the same egg source?
- Is the rate per started cycle, per egg collection, per thawing cycle or per transfer?
- Which treatment years and how many cases are included, and how do you account for missing follow-up?
- How do you follow up outcomes for patients who return to another country?
