Dr. Mary Stephenson is internationally renowned for her clinical and research expertise in recurrent pregnancy loss. She is double board-certified in both Obstetrics & Gynecology and Reproductive Endocrinology & Infertility, with additional training in reproductive immunology and genetics. She 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.
A tireless patient advocate, Dr. Stephenson emphasizes the importance of finding out why miscarriage occurs. She recommends sending miscarriage tissue for chromosome testing to determine whether the miscarriage was “explained”, due to an abnormal number of chromosomes, or “unexplained”, with correct number of chromosomes. Dr. Stephenson founded the University of Illinois Recurrent Pregnancy Loss Program, which offers comprehensive evaluation and management, and close monitoring of pregnancy in the first trimester.

For over two decades, Dr. Stephenson’s research has focused on therapeutic interventions for recurrent pregnancy loss and infertility. Dr. Stephenson led the largest clinical trial to date on the use of intravenous immunoglobulin (IVIG) in recurrent miscarriage. Although the results showed IVIG was not of benefit, with preconception evaluation and close monitoring in early pregnancy, once an intrauterine pregnancy was seen on ultrasound a live birth rate of 94% was attained.
Dr. Stephenson joined the UIC Department of Obstetrics and Gynecology in 2012 as the Department Head and Theresa S. Falcon-Cullinan Professor.
Presently, Dr. Stephenson is Site Investigator for three randomized trials:
- The TRUST Trial (NTR1676), which evaluated whether hysteroscopy metroplasty improves reproductive outcomes in women with a septate uterus, has recently been published.
- ACTorNOT Trial (NCT02152696) which compares three currently available management strategies for women with a persisting pregnancy of unknown location (PPUL). The results of the trial will be published shortly.
- ALIFE2 Trial (NTR3361) which evaluates whether prophylactic low molecular weight heparin (LMWH) improves live birth rate in women with recurrent miscarriage and an inherited thrombophilia. Patient enrolment is complete, the results of the trial will be published shortly.
Dr. Stephenson has longstanding research collaborations with the University of British Columbia to identify submicroscopic additions or deletions to miscarriage chromosomes, with the ultimate aim of discovering “miscarriage genes”.
In 2017, the second edition of “Early Pregnancy” was published (Dr. Farquharson and Dr. Stephenson, Co-Editors, Cambridge University Press); this textbook embraces a multidisciplinary approach to the evaluation and management of recurrent pregnancy loss.
Dr. Stephenson is featured in the popular book by Jon Cohen, “Coming to Term: Uncovering the Truth about Miscarriage” (Rutgers University Press).
Dr. Stephenson was an Associate Editor for the journals Human Reproduction Update, Huma Reproduction and Fertility & Sterility; she is still an active reviewer for several high-impact journals. Dr. Stephenson served as the International Advisor for the Early Pregnancy Special Interest Group for the European Society for Human Reproduction & Embryology (ESHRE) from 2007-2019. She was the Founding Chair of the Early Pregnancy Special Interest Group for the American Society of Reproductive Medicine.
In 2016, Dr. Stephenson was 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.
In June 2018, Dr. Stephenson was awarded Fellow Ad Eundem by the Royal College of Obstetricians and Gynaecologists, a prestigious award bestowed to individuals who have made significant contributions to the advancement of Obstetrics Gynaecology. Dr. Stephenson was recognized, “for her work as one of the world’s leading clinicians and translational researchers in the field of recurrent pregnancy loss.”
