Alex Polotsky, M.D., M.Sc., FACOG, earned his medical degree from the Albert Einstein College of Medicine in Bronx, New York. At first, he had a strong interest in becoming a general internal medicine doctor. But it was during his clinical rotations that he was exposed to reproductive endocrinology and infertility, and knew he wanted to dedicate his expertise to a narrow specialty where he is expected to be an expert in all aspects of fertility care rather than a broader field. Upon completing his residency in Obstetrics and Gynecology at New York Presbyterian Hospital – Weill Cornell Medical Center, Dr. Polotsky returned to the Albert Einstein College of Medicine for his fellowship in reproductive endocrinology and infertility. While there, he subsequently earned his Master of Science degree in Clinical Research where his thesis extensively explored the links between adolescent obesity and reduced lifetime fertility. Dr. Polotsky has an extensive teaching record at Albert Einstein College of Medicine and the University of Colorado where he became a full Professor of OB/GYN, Fellowship Director for Reproductive Endocrinology and Infertility, and sat on many Doctoral/Master’s Thesis Committees. Dr. Polotsky is board certified in obstetrics and gynecology as well as reproductive endocrinology and infertility (REI). He is a board examiner for REI with the American Board of Obstetricians and Gynecologists (ABOG). His passion for REI stems from the field’s unique combination of medical management and surgical procedures along with the importance of psychological care for patients. Beyond treating patients for infertility, Dr. Polotsky is actively involved in research. Key research focuses include the reproductive epidemiology and predictors of IVF success and connections between obesity and infertility as well as male infertility. An avid contributor to peer-reviewed journals, Dr. Polotsky has published more than 80 articles featuring topics like polycystic ovary syndrome (PCOS), assisted reproductive technology, connections between ethnicity and reproductive ability, effects of body mass on fertility (men and women), and more. He co-authored with Dr. Nanette Santoro a chapter entitled “Nutrition and Reproduction” for the Yen and Jaffe’s Reproductive Endocrinology, the most recommended book in the field. Additionally, his nearly 100 presentations on scientific abstracts have jet-set Dr. Polotsky to Italy, Canada, Switzerland, Austria, Israel as well as across the United States.
