Dr. Mary Stephenson is internationally renowned for her clinical and research expertise in Recurrent Pregnancy Loss. Her postgraduate training in reproductive immunology and genetics has facilitated her “bench to bedside” approach to patient care.
She is Board Certified in Obstetrics & Gynecology, and in Reproductive Endocrinology & Infertility.
Dr. Stephenson is an expert in the management of early pregnancy loss, recurrent pregnancy loss, fetal demise, Antiphospholipid Syndrome, autoimmune disorders in pregnancy, and recurrent IVF failure. Click here to learn more about the UI Health Recurrent Pregnancy Loss Program.
Over the past two decades, Dr. Stephenson has assessed therapeutic interventions for recurrent pregnancy loss and infertility. She recently completed the largest trial to date on the use of intravenous immunoglobulin (IVIG) in recurrent miscarriage. Although the results showed IVIG was not of benefit, preconception care and close monitoring resulted in a live birth rate of 94%, once a pregnancy was seen on ultrasound.
Dr. Stephenson emphasizes the importance of finding out why miscarriage occurs. She recommends sending miscarriage tissue for chromosome testing to determine whether the miscarriage is “explained,” due to an abnormal number of chromosomes, or “unexplained,” when the normal number of chromosomes are found.
Dr. Stephenson has a longstanding research collaboration with the University of British Columbia, to identify submicroscopic chromosomal imbalances in miscarriages which may lead to the discovery of “miscarriage genes”.
In 2010, Dr. Stephenson co-authored the textbook, “Early Pregnancy”, which embraces a multidisciplinary approach to the evaluation and management of recurrent pregnancy loss. The second edition is in press. Dr. Stephenson is featured in the popular book by Jon Cohen, “Coming to Term: Uncovering the Truth about Miscarriage”.
Dr. Stephenson is Associate Editor for the journal Human Reproduction Update, Associate Editor for the journal Fertility & Sterility, and past Associate Editor for the journal Human Reproduction. Dr. Stephenson is the International Advisor, Early Pregnancy, for the European Society for Human Reproduction & Embryology (ESHRE). In 2016, Dr. Stephenson became the President of the International Gynecologic Society.
Dr. Stephenson has been awarded Best Doctors® (top 5% nationally) since 2005, America’s Top Doctors® Castle Connolly’s (top 1% nationally) since 2014, and Chicago Magazine's Top Doctors for Women: Reproductive Endocrinology (top 1% in Chicago) since 2014.
