Biographical Info

Dr. Isaac Kligman is a Professor of Obstetrics and Gynecology and Reproductive Medicine at the Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine (CRM) at Weill Cornell Medical College. Board certified in both Obstetrics and Gynecology and Reproductive Endocrinology and Infertility, he is an internationally renowned fertility specialist.

Dr Kligman provides fertility preservation services for women who want to cryopreserve (freeze) their eggs and desire to achieve a pregnancy later in their reproductive life. With the refinements in this technology such as oocyte (egg) vitrification, this procedure has become widespread and a good alternative to overcome the impact of aging on a woman’s ovary. He also treats patients with a wide range of reproductive and infertility disorders. He helps patients with fertility issues become pregnant using the most sophisticated assisted reproduction techniques, including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). He is skilled in laparoscopy and hysteroscopy, two minimally invasive surgical modalities. With laparoscopy, he treats anatomical causes of infertility such as endometriosis, pelvic scar tissue, blocked fallopian tubes and ovarian cysts. He removes polyps, fibroids and scar tissue and corrects congenital malformations such as uterine septum with hysteroscopy.

Dr. Kligman joined the Center for Reproductive Medicine in 1993 for his fellowship training in Reproductive Endocrinology and Infertility under the direction of Dr. Zev Rosenwaks, and became a full-time faculty member at CRM upon completion of his fellowship in 1995. Prior to joining CRM, he completed a research fellowship in Reproductive Biology and Endocrinology at the Perelman School of Medicine at the University of Pennsylvania in 1989 and his residency in Obstetrics and Gynecology at the University of Maryland Medical Center in 1992. Dr. Kligman completed his M.D. in 1981 and his residency in 1987 at the Unversidad Javeriana in Bogota, Colombia.

Dr. Kligman has made countless presentations on research and treatment topics in reproductive medicine to audiences throughout the United States, Japan, Europe and South America. He has authored and co-authored numerous textbook chapters as well as dozens of articles in leading peer-reviewed medical journals. He is also a member of the Editorial Boards of Fertility and Sterility and Reproducción Humana, the official journal of the Latin American Association of Reproductive Medicine (ALMER). Dr. Kligman is an active member of several professional societies including the American Society for Reproductive Medicine, the American College of Obstetricians and Gynecologists and the New York Obstetrical Society.

Dr. Kligman is profiled in Marquis Who's Who in America, Marquis Who's Who in the World and received the Albert Nelson Marquis Lifetime Achievement Award. He has been listed in New York Times Magazine's Best Doctors and Castle & Connolly's Top Doctors - New York Metro Area.
