Dr. Regina Turner graduated from the University of Pennsylvania’s School of Veterinary Medicine in 1989. After a year in a private mixed animal practice, Dr. Turner returned to Penn’s New Bolton Center to complete a 2-year residency in Large Animal Reproduction. She then stayed on as a lecturer and became a Diplomate of the American College of Theriogenologists in 1994. Between 1995 and 1999, Dr. Turner completed a PhD in Cell and Molecular Biology at the University of Pennsylvania’s School of Medicine, focusing on the molecular biology of mammalian sperm motility. After completion of her PhD, she was hired as a faculty member in Penn’s Veterinary School at New Bolton Center where she currently serves as a Professor of Large Animal Reproduction and Chief of the Section of Reproduction and Behavior. Although Dr. Turner sees a wide range of reproduction-related cases, her primary interest is stallion fertility. In this regard, her research interests have focused on the effects of aging on testicular function and the molecular and cellular regulation of sperm motility.
