“The Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine is committed to the finest patient care and continued research excellence. This combination continually improves the care we deliver and keeps our services at the forefront of the field. As soon as new treatments are proven safe and effective in treating infertility, couples will find them at Cornell's Center for Reproductive Medicine.”

Dr. Isaac Kligman is an Associate 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 wish to cryopreserve (freeze) their eggs and achieve pregnancy later in their reproductive life. With refinements in this technology, such as oocyte (egg) vitrification, this procedure has become widespread and is a strong option for overcoming the impact of aging on a woman’s ovaries. 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 reproductive 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. With hysteroscopy, he removes polyps, fibroids, and scar tissue, and corrects congenital malformations such as a uterine septum.

Dr. Kligman joined the Center for Reproductive Medicine in 1993 for fellowship training in Reproductive Endocrinology and Infertility under the direction of Dr. Zev Rosenwaks, and became a full-time faculty member 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 Universidad Javeriana in Bogotá, 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. He is profiled in Marquis Who’s Who in America and Marquis Who’s Who in the World, and he has received the Albert Nelson Marquis Lifetime Achievement Award. He has also been listed in New York Times Magazine’s Best Doctors and Castle Connolly’s Top Doctors – New York Metro Area.
