Dr. Leclerc is a professor in the Department of Obstetrics, Gynecology and Reproduction of the Faculty of Medicine at Laval University. Being a regular researcher in the Reproductive, Maternal and Child Health axis at the CHU of Quebec-Laval University Research Centre, he is also a member of the Centre for Research in Reproduction, Development and Intergenerational Health of Laval University (CRDSI), and is part of the Réseau québécois en reproduction (RQR). Dr. Leclerc is involved in the training of graduate students enrolled in the Molecular Medicine and Molecular and Cellular Biology programs of the Faculty of Medicine, as well as Animal Sciences of the Faculty of Agricultural and Food Sciences. He is also a member of the Molecular Medicine Program Committee.

Dr. Leclerc’s research interests are in the field of male infertility. Following ejaculation, spermatozoa, although morphologically whole and motile, are unable to fertilize an egg. They must undergo a maturation stage that normally occurs in the female genital tract as they move to the fertilization site. The intracellular mechanisms that cause metabolic and membrane changes that make sperm capable of interacting and fertilizing the egg are at the heart of Dr. Leclerc’s research activities.

His research also focuses on the mechanisms involved in the interactions between gametes during fertilization, and more specifically on the proteins mediating the recognition and binding of spermatozoa to the egg.

About 7% of men suffer from infertility and, for nearly one-third, the reasons are unknown. Dr. Leclerc’s research may help to better understand the causes of these cases of unexplained infertility. In addition, a better understanding of the physiology and fertilization potential of sperm improves the success rate of medically assisted reproduction and cryopreservation techniques by reducing their deleterious effects.
