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, camelids, cervids and humans. Results of studies on ovarian function in women by Dr. Adams and co-workers at the University of Saskatchewan was cited as one of the top 100 scientific discoveries of the year by Discover Magazine.

Technical applications resulting from his work include:

Dr. Adams' current research focuses on ovulation-inducing factor in seminal plasma, factors influencing oocyte competence in cattle and synchrotron-based biomedical imaging.

As a result of his recent Proceedings of the National Academy of Sciences publication on "The nerve of ovulation-inducing factor," a Google search for the terms "’Gregg Adams’ semen protein female brain" yielded 30 pages of hits. His top 10 papers (by citation) have been cited 134 times on average (range 94 to 376). H-index: 38.
