Background

Dr. Reuben Mapletoft received a DVM from the University of Guelph in 1967, and MS (1975) and PhD (1977) degrees in Endocrinology and Reproductive Physiology from the University of Wisconsin. He joined the WCVM as Director of Clinical Research in 1977. He became Head of the Department of Herd Medicine and Theriogenology (now Large Animal Clinical Sciences) in 1998. In July, 2002, Dr. Mapletoft took a one year Leave of Absence to consult with Bioniche Animal Health, which has led to a 50% appointment with the University of Saskatchewan.

Dr. Mapletoft's research in reproductive biology and the application of assisted reproductive technologies in cattle spans more than 30 years. He is a Past-president of the International Embryo Transfer Society (IETS) and Founding President of the Canadian Embryo Transfer Association (CETA), and he was Chairman of the Import/Export Committee of the IETS for 10 years. He is currently a member of the Certification Committee of CETA and several IETS committees.

Dr. Mapletoft is also very active in technology transfer; he has given over 150 invited lectures in more than 30 countries and has trained graduate students from all over the world. He has contributed more than 300 papers to published conference proceedings, and authored more than 130 refereed publications. He has conducted over 3 dozen embryo transfer workshops for more than 200 veterinary professionals from around the world. In 2003, the University of Saskatchewan honored Reuben with its Distinguished Researcher Award, and in 2005, he was awarded and Earned Doctorate by the university of Saskatchewan. HR WIDTH="100%">

Research Focus

Dr. Mapletoft is well known for his work in bovine embryo transfer, estrus synchronization and superovulation. His embryo transfer protocols have become the de facto standard for clinical use worldwide, and he has been instrumental in developing the embryo transfer industry in Canada and around the world. Much of Dr. Mapletoft's recent work has revolved around the manipulation of ovarian follicular wave dynamics for superovulation, estrus synchronization and timed-breeding in cattle. He also has an active research program utilizing in vitro fertilization technology to evaluate oocyte competence and the effect of sperm morphology on fertilization and zygote development. His team is also researching the use of non-biological additives in the culture of oocytes and embryos and the cryopreservation of sperm, oocytes and embryos.
