|||||||||
Dr. Claudio Benadiva is the Medical Director of the Center for Advanced Reproductive Services, affiliated with the University of Connecticut. In addition to being a Professor of Obstetrics and Gynecology, he is a Fellow of the American Congress of Obstetricians and Gynecologists and board-certified in obstetrics and gynecology and reproductive endocrinology and infertility.
Dr. Benadiva is among the very few physicians who are certified by the American Board of Bioanalysis as a High Complexity Laboratory Director, making him uniquely suited to integrate both clinical and laboratory protocols in an IVF program. He has been awarded "Best Doctor in America" every year since 2001.
Dr. Benadiva graduated from the University of Buenos Aires School of Medicine in 1981 and completed his residency in OB/GYN at the UConn School of Medicine. He completed a Research Fellowship in Reproductive Biology and Endocrinology at the University of Pennsylvania School of Medicine in 1988, and a Clinical Fellowship in Reproductive Endocrinology at The New York Hospital-Cornell Medical Center in 1995.
Dr. Benadiva has done extensive research in reproductive biology and endocrinology since 1986. His work has resulted in over 80 peer-reviewed articles, 160 abstract presentations and invited book chapters.
He continues to lecture nationally and internationally, with a special interest in ovulation induction for in-vitro fertilization (IVF), preimplantation genetic testing (PGT), and methods for prevention of ovarian hyperstimulation syndrome (OHSS).
