    His clinical and research interests resulted in more than 40 publications on the topics of single embryo transfer, fertility preservation including oocyte vitrification (egg freezing), preimplantation genetic diagnosis (PGD), and diminished ovarian reserve. A study led by Dr. Forman demonstrated for the first time that embryos formed after egg freezing are not at an increased risk of being chromosomally abnormal, an accomplishment that was deemed a “watershed” in assisted reproductive technology by one of the world’s experts on cryopreservation. Another landmark study led by Dr. Forman showed for the first time that similar delivery rates could be achieved by transferring one chromosomally-normal embryo as compared to two unscreened embryos while eliminating the risk of twins.
