EuMAR 1
EuMAR 1 was a three-year project (2023-2025), co-funded by the EU4Health program at the European Commission (DG SANTE) and run by ESHRE. Its aim was to develop a pan-European registry of prospective cycle-by-cycle data on the use and outcomes of medically assisted reproduction (MAR) treatments. EuMAR addresses the need for:
- Transparency and accessibility of data
- Quality assurance and surveillance
- Standardisation of parameters and definitions for comparability of data
- Flexibility to connect to other registries in the future
- The possibility to calculate cumulative outcomes and understand cross-border care trends
- A patient-centred approach, where patients' perspectives are heard, and they have power over their own treatment data

EuMAR 1 Pilot Study
The EuMAR registry was tested in a pilot study from 1 July to 31 December 2024 in some clinics in Germany, Portugal, Slovenia and Estonia. The EuMAR pilot study was a feasibility project aimed at testing different methods for the submission of cycle-by-cycle data on MAR treatments from EU Member States into a single registry. The pilot study helped us to identify challenges and best practices before the registry is extended to all European countries.
The pilot study was evaluated following a previously defined pilot study plan. The results of the pilot study were published in D6.1 Validation Report. The pilot study demonstrated the feasibility of establishing a cycle-by-cycle MAR registry in Europe, which led to the transition towards EuMAR 2.
