Evaluation and management of recurrent early pregnancy loss.

Recurrent pregnancy loss affects up to 5% of couples trying to establish a family. Evaluation classically begins after 3 consecutive miscarriages of less than 10 weeks of gestation but may be warranted earlier if a prior miscarriage was found to be euploid, or if there is concomitant infertility and/or advancing maternal age. The evaluation begins with an extensive history and physical, followed by a diagnostic screening protocol. Management must be evidence-based; unproven treatments should be avoided. If no factor is identified, many couples will still eventually have a successful pregnancy outcome with supportive therapy alone.
