不同的國際組織對於反覆性流產(recurrent pregnancy loss)的定義有所差異,可以分成美國、歐洲、英國等國家,大多數定義都是要超過兩次第一孕期內的流產,美國生殖醫學學會(American Society for Reproductive Medicine, ASRM)的定義需要用超音波或組織學確認多次流產才能符合設定,歐洲生殖醫學會(European Society of Human Reproduction and Embryology, ESHRE)不論是否連續只要兩次就可以診斷為反覆性流產,而英國的皇家婦產科學院(Royal College of Obstetricians and Gynaecologists, RCOG)則規定要流產三次以上才能符合,因此在閱讀各家指引的時候,需要特別注意每個指引中對於名詞定義的微妙差異,才能妥當使用。
