Sociedad Española de Fertilidad (Spanish Fertility Society)

Overview

SEF is the Spanish national fertility society and operates the Spanish Fertility Registry (Registro Nacional de Actividad y Resultados de los Centros de Reproducción Humana Asistida), which publishes annual outcome data for IVF clinics in Spain. SEF membership is voluntary but the registry submission is required for clinics performing assisted reproduction techniques.

Founded: 1979 · Headquarters: Madrid, Spain

What It Covers

SEF registry data includes clinic-level cycle counts, age-stratified pregnancy rates, multiple-pregnancy rates, and complication rates. The registry is one of the more granular national fertility-outcome datasets internationally and allows direct clinic-to-clinic comparison within Spain.

Limitations

SEF registry submission is mandatory for licensed clinics but specific cohort selection criteria can affect the published rates. Comparison between clinics requires careful consideration of the patient mix (age, prior treatment, donor cycles). Membership of the Society itself is voluntary.

Renewal and Validity

Registry submission is annual; SEF Society membership is annually renewable.
