Michael Dahan, MD, Assistant Professor in the Obstetrics and Gynecology Department at McGill University, Associate at OriginElle Fertility Centre, has been recognized by Marquis Who’s Who Top Doctors for dedication, achievements, and leadership in fertility medicine.

With more than 20 years of experience in the field of women’s health, Dr. Dahan is an associate for the OriginElle Fertility Clinic and Women’s Health Centre, as well as an assistant professor for the division of reproductive endocrinology and infertility in the department of obstetrics and gynecology at McGill University. He joined the staff at OriginElle in 2010 and has remained passionate about his work at the center since then. In addition to his primary roles, he has been active with Stanford University as a clinical instructor in the division of general obstetrics with the department of obstetrics and gynecology, a supervisor with the medical school summer research internship program, a research scholar in women’s reproductive health, and a teaching assistant with the Human Health and Disease 223 Gynecology Laboratory.

Dr. Dahan previously worked as an assistant professor with Washington University, having been with the University of California, Davis, as a supervisor in the undergraduate summer research internship, and a supervisor, clinical instructor, medical student lecturer, peer tutor and supervisor with the University of California, San Diego. He has also served as an academic physician with McGill University and a clerk of biochemistry, neuroscience, and nephrology in epidemiology and statistics with the State University of New York at Stony Brook.

Throughout his career, Dr. Dahan’s research has moved reproductive health forward, and he was the first physician to describe vasospasm causing pituitary hypofunction and resultant permanent damage, known today as Dahan’s Syndrome. In addition, he facilitated the first successful pregnancy and live birth obtained with serial vitrification of embryos collected through in-vitro maturation of oocytes and array-cgh and pgd. Dr. Dahan also set a world record egg collection, collecting 125 eggs from a single patient undergoing in-vitro maturation of human oocytes without any gonadotropin stimulation. By utilizing this method, there was no risk of ovarian hyperstimulation syndrome.

Dr. Dahan began his career as a student at McGill University, obtaining a Bachelor of Arts in archaeology with great distinction. He then joined the State University of New York at Stony Brook, earning a Doctor of Medicine. He went on to complete a residency in obstetrics and gynecology at Long Island College Hospital, followed by a fellowship in reproductive endocrinology and infertility at the University of California, San Diego. He is recognized as a fellow of the American Congress of Obstetricians and Gynecologists and a board certified physician in reproductive endocrinology and infertility. Dr. Dahan is certified by the Royal College in obstetrics and gynecology, by the American Board of Obstetrics and Gynecology in general obstetrics, gynecology, reproductive endocrinology and infertility, and he is licensed to practice in Quebec, Missouri, California and New York.

A leading voice in the field, Dr. Dahan has published more than 100 peer-reviewed medical articles and more than 100 peer-reviewed abstracts. He authored seven book chapters, and more than 130 newspaper and magazine articles have been written regarding his findings. In addition, Dr. Dahan has been invited to give medical presentations in more than 50 cities and more than 20 countries. In 2017, his research article was identified by the American Board of Obstetrics and gynecology as an essential reading for applicants seeking board certification and recertification.

Dr. Dahan believes that the most gratifying part of his career is helping couples conceive a child after many failed attempts at other infertility centers. This drives him to always perform his best work and to continue in the research that has led to his achievements. In recognition of his contributions, Dr. Dahan was nominated 12 times as a Guardian Angel of the Royal Victoria Hospital Foundation, and he was also selected by Stanford University to fill its Women’s Reproductive Health Research Scholar position. He earned an Outstanding Clinical Scholar/Fellow Teaching Award from Stanford University, an R. Howard Webster Foundation Research Award and Grant for his contributions in reproductive medicine and menopausal research, and he was selected by the Consumers’ Research Council of America as one of America’s Top Obstetricians and Gynecologists. Looking to the future, Dr. Dahan intends to continue working hard for his patients’ continued success while taking on new research opportunities in his field as they arise.

Some of the noted accomplishments in his career since his fellowship have been his work on the Canadian Human Immunodeficiency Virus (HIV) Pregnancy Planning Guidelines and being the first to describe vasospasm causing pituitary hypofunction and resultant permanent damage that has been named Dahan’s Syndrome. In addition, Dr. Dahan was the first to describe sever early ovarian hyperstimulation syndrome (OHSS) after GnRH-agonist trigger and 1500 IU of hCG.
