Each table measures a different treatment stage: transfer, thawing or egg collection. Compare the same treatment and age group across countries.

The EU reference is the median of available EU-27 country rates for the same treatment, age band and year (2020). Each country has equal weight. It describes the middle country result, not the pooled success rate of all EU patients.

About these statistics

These are clinical pregnancy rates, rather than birth rates or the cumulative chance of a baby from a full course of treatment. The 2020 reporting year was affected by the pandemic. Patient populations, registry coverage and reporting completeness differ between countries.

Age bands follow the source labels: <34, 35–39 and 40+. The source does not clarify the boundary for age 34. Donor results use recipient age and combine donor treatment variants. Age-specific cohort sizes and separate donor transfer variants are not provided in these tables. “Not published” means this report provides no corresponding age-specific rate.

EU-27 membership is used for the benchmark. Missing country rates are omitted, never counted as zero. Non-EU reporting countries are excluded from the reference. Country rates are descriptive; differences do not establish clinic quality or a personal prognosis.

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?

Frequently Asked Questions

Common questions about IVF in New Zealand.

Reciprocal IVF, also known as shared motherhood, is legally allowed in New Zealand for lesbian couples, and the law recognizes both partners as legal parents of the child.

In New Zealand, the woman who provides the eggs is considered the genetic mother, while the woman who carries the pregnancy is the gestational mother; however, both are legally recognized as parents. Couples pursuing ROPA generally need to meet residency requirements, such as being New Zealand citizens or residents with a valid work visa of at least two years, and women are typically required to be 39 years old or younger at the time of referral for publicly funded treatment.

Additional requirements for public funding often include specific BMI limits, being non-smokers, and demonstrating a cause of infertility or unsuccessful attempts at conception. While these criteria may not apply to privately funded ROPA, individual clinics will have their own assessment processes.
