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. He also completed a fellowship in Reproductive Endocrinology and Infertility at the University of California in San Diego and was trained by the internationally renowned Drs. Samuel S. C.

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, indicating a condition similar to menopause. We believe this to be the worst case of ovarian reserve on record where treatment has resulted in a live birth.
- 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.
- Several full term deliveries in women over 44 years of age at the time of conception using their own eggs to conceive.
Dr. Dahan has authored over 100 peer-reviewed publications and abstracts and has been awarded over $1 million in research grants. He was Chair of the Associate committee of the Society for Reproductive Endocrinology and Infertility from 2003 to 2005.
