Bio

Dr Younglai obtained his PhD from McGill University on work related to the metabolism of 16a-hydroxysteroids in man. He then spent two years of postdoctoral work with Dr Roger Short in Cambridge, England where he introduced the two-cell theory of ovarian steroidogenesis using the horse follicle as a model.

On his return to Canada he joined the department of Obstetrics and Gynecology at McMaster University where he has supervised the research of a number of Masters and Doctoral students. He has made many contributions to the hormonal changes during the estrous cycle and pregnancy of domestic animals and other exotic species such as the bat.

He has actively participated in over a dozen committees and is/was on numerous professional organizations, such as the Canadian Fertility and Andrology Society, Society for the Study of Reproduction, the American Society for Reproductive Medicine and the European Society for Human Reproduction and Embryology, including being President of Canadian Investigators in Reproduction for a year.

He has over 190 publications in peer reviewed journals, held research grants from a number of agencies over the years including CIHR. He reviews manuscripts for journals and applications for grant awards. He is Editor-in-Chief of “Reproductive Biology Insights” and an associate editor of “Human Reproduction”.

Research Interests

Dr YoungLai is interested in many aspects of the control of fertility and in particular the effects of environmental toxicants on gonadal function. His recent research was focused on the nongenomic (rapid) effects of ovarian steroids and insecticides, an emerging area of intense scientific interest.
