Evidence-based investigations and treatments of recurrent pregnancy loss

Abstract

Purpose of review: The majority of investigations and treatments offered to women with recurrent pregnancy loss are not evidence-based. In this review a critical analysis is given of the current management of recurrent pregnancy loss often recommended in meta-analyses and guidelines.

Recent findings: Our knowledge of genetic, endocrine, thrombophilic and immunological causes of recurrent pregnancy loss has been improved significantly, primarily by the introduction of modern laboratory techniques. Most clinical trials in this area, however, are still subject to serious methodological flaws.

Summary: At present, the clinician must base their clinical practice on the few high-quality observational studies and intervention trials available rather than on meta-analyses, as there is a scarcity of good clinical trials. More high-quality clinical studies are urgently needed in this area.
