Original filing
A PubMed search of "thrombophilia" and "infertility" yields only 98 articles, the majority found in foreign medical journals and subspecialty journals with narrow readerships. Outside of Assisted Reproduction Clinics at academic medical centers, health care providers have limited awareness of the literature supporting thrombophilia evaluation and treatment in patients with recurrent pregnancy loss. As a result, women may suffer through years of repeated miscarriages before a thrombophilia evaluation is performed. By the time thrombophilia has been diagnosed as the cause of recurrent pregnancy loss, couples have often exhausted their personal savings on costly assisted reproductive therapies and present frustrated and psychologically exhausted. In this study, we will evaluate the frequency of thrombophilia as a cause of recurrent pregnancy loss and provide insights into our patient care experience at BWH.
