John Parrish

John Parrish is a Professor in the Department of Animal and Dairy Sciences at the University of Wisconsin-Madison, within the College of Agricultural and Life Sciences. He holds a B.S. from California State University, Fresno (1977), a Ph.D. from Cornell University (1983), and completed a postdoctoral fellowship at UW-Madison. His research focuses on male reproductive physiology, including sperm capacitation, in vitro fertilization, and the impact of environmental factors on fertility across species such as cattle, pigs, and humans. Parrish has authored seminal papers in reproductive biology with high citation counts.

He teaches courses in reproductive physiology and endocrinology, emphasizing technology integration in education. Notable awards include the Chancellor’s Distinguished Teaching Award (2015) and the American Society of Animal Science Distinguished Teaching Award (2018). His work spans species like cattle, swine, equines, and humans, addressing male fertility challenges through biochemical and imaging approaches.

Parrish’s publications explore topics like bovine sperm capacitation, heat stress effects on spermatogenesis, and nanoparticle applications for fertility enhancement. He advises students in reproductive biology and has contributed to national and international academic committees, emphasizing teaching excellence and scholarly pedagogy.
