Eric Forman, MD, HCLD
President & Board Member

Dr. Eric Forman is the Medical and Laboratory Director at Columbia University Fertility Center.
He oversees the medical practice as well as the IVF embryology and andrology laboratories. He also actively sees patients with infertility and those seeking to preserve their fertility. Dr. Forman has extensive clinical and laboratory research experience. He has published more than 40 articles in peer-reviewed journals on a wide range of topics in assisted reproductive technology (ART).
He has a special interest in using preimplantation genetic screening (PGS) to optimize IVF and improve selection for elective single embryo transfer (eSET). A randomized controlled trial he led demonstrated, for the first time, that transferring a single chromosomally-normal embryo (link is external and opens in a new window) can achieve the same live birth rates as transferring two untested embryos. After publication of this paper, eSET rates skyrocketed and the American Society for Reproductive Medicine references Dr. Forman’s study in its guideline on the number of embryos to transfer in IVF. He also has an interest in fertility preservation, and a study he led proved that egg freezing using the rapid vitrification technology does not increase the risk of genetic abnormalities in the resulting embryos. This study was cited as a “watershed in ART” by one of the world’s leading experts on cryopreservation.
