Other Appointments

Research Interests

Dr. Adams has broad interests in basic and applied aspects of reproductive science and medicine, and he is recognized internationally for his work on ovarian function.

He has published classic studies of ovarian follicle development, ovulation and fertility in several species including cattle, llamas and alpacas, deer, bison, and humans. Studies on ovarian function in women by Dr. Adams and co-workers at the University of Saskatchewan were cited as one of the top 100 scientific discoveries of the year by Discover Magazine. He has worked with a variety of wild terrestrial and marine mammals and his research team recently celebrated the birth of the world’s first bison calves through the use of IVF and embryo freezing.


Technical applications resulting from his work include:

Dr. Adams' current research focuses on 1) ovulation-inducing factor in seminal plasma, 2) the establishment of a germplasm biobank for Canada’s threatened Wood Bison, 3) novel aromatase inhibitor-based method of ovarian synchronization in animals, and 4) embryonic diapause in pinnipeds.


His discoveries on "The nerve of ovulation-inducing factor" and “World's first in-vitro bison calves born at University of Saskatchewan” have been publicized widely in the popular press.
