ABSTRACT
Background: The definition of recurrent pregnancy loss varies according different authors and consensus: the American Society for Reproductive Medicine (ASRM) defines RPL when two or more pregnancy losses occur, and the European Society of Human Reproduction and Embryology (ESHRE) defines it as three or more pregnancy losses, not necessarily intrauterine. To this day, there is no uniform approach that serves as a guide in the diagnosis and treatment of this condition; this is why, in up to 50% of the cases of RPL, it will not be possible to identify the specific etiology. Objetive: To report on the recurrent pregnancy loss, in order to harmonize concepts and suggest a diagnosis and treatment for this condition approach. Method: The search strategy included, but was not limited to keywords like: recurrent abortion, infertility, habitual abortion, primary antiphospholipid syndrome, lupus anticoagulant, anti-cardiolipin antibodies and anti B2 glycoprotein I.
