Terminology for pregnancy loss prior to viability: A consensus statement from the ESHRE early pregnancy special interest group

Abstract

Pregnancy loss prior to viability is common and research in the field is extensive. Unfortunately, terminology in the literature is inconsistent. The lack of consensus regarding nomenclature and classification of pregnancy loss prior to viability makes it difficult to compare study results fromdifferent centres. In our opinion, terminology and definitions should be based on clinical findings, and when possible, transvaginal ultrasound. With this Early PregnancyConsensus Statement, it is our goal to provide clear and consistent terminology for pregnancy loss prior to viability.
