Michael H. Dahan, MD, FACOG, FRCSC

Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, McGill Reproductive Center, McGill University, Royal Victoria Hospital, Montreal, QC, Canada

Dr. Dahan is a fellow of the American College of Obstetrics and Gynecology and of the Royal College of Surgeons of Canada, Obstetrics and Gynecology Division. He is board certified in Obstetrics and Gynecology and Reproductive Endocrinology as well as in Infertility, and serves as assistant professor in the department of Obstetrics and Gynecology at McGill University.

Dr. Dahan graduated from the State University of New York at Stony Brook in medicine and then completed his residency in Obstetrics and Gynecology at Long Island College Hospital campus of the State University of New York at Down State. He also completed a fellowship in Reproductive Endocrinology and Infertility at the University of California in San Diego.  After completing his fellowship, Dr. Dahan was on faculty at Washington University in St. Louis Missouri and Stanford University in California, before joining McGill University

Dr. Dahan’s areas of expertise include in vitro fertilization, in vitro maturation of eggs, egg freezing, polycystic ovary syndrome, endometriosis, male infertility and recurrent pregnancy loss. He also specializes in fertility preservation for cancer patients, tubal factor infertility, ovulation induction and sperm insemination, egg donors and factors affecting menstrual periods.

Dr. Dahan has several remarkable accomplishments and world firsts in fertility care; these notable contributions include:

• A live birth using a patient’s own eggs and whose blood FSH levels were 80 iu/l, but was not yet in menopause. We believe this to be the worst case of ovarian reserve on record where treatment has resulted in a live birth, without a history of premature ovarian insufficiency.

• Collecting 125 eggs (most probably a world record) from one woman at one time while doing in vitro maturation, hence completely avoiding the risk of ovarian hyper stimulation syndrome. The treatment resulted in a live birth.

 • The only healthy full term live birth of a single baby after IVF in a woman with two uteri and born without a vagina. 

• A word-first full term live birth after serial in vitro maturation in a woman with Fragile X syndrome carrier status and decreased ovarian reserve who failed to stimulate with IVF. She underwent PGD and genetic testing of the embryos. 

• The name Dahan’s syndrome has been applied to pituitary injury due to vasospasm, which he first described in the medical literature. 

• He is one of the authors of the pregnancy planning in HIV Canadian guidelines. 

• He developed what has recently been termed the Dahan technique for oocyte retrieval in women undergoing in-vitro maturation of oocytes

Dr. Dahan has authored over 120 peer-reviewed publications and has been awarded over $1.3 million in research grants. He was Chair of the Associate committee of the Society for Reproductive Endocrinology and Infertility from 2003 to 2005. He is currently or has been in the past on the editorial board of over 30 peer reviewed journals.

Dr. Dahan was thrice chosen as one of the best Obstetricians/Gynecologists in America by the Consumers’ Research Council and was the 2008 recipient of the R. Howard Webster award given by the Research Institute of McGill University. He was selected for Marquis Who is Who in Medicine.
