thème 2-ciape


Thematic Leader: Géraldine Delbès

The objective of this theme is to determine the regulatory mechanisms underlying the reproductive effects induced by endocrine disruptors. Research on the reproductive axis disruption includes the development of rapid and effective models for the detection of potential endocrine disruptors with a focus on cell-based models representing the male and female reproductive systems. It also includes models related to hormones (steroids, neuroendocrine secretion) to test the reproductive potential of endocrine disruptors. The expertise covers both aquatic and terrestrial species, from invertebrates to mammals.


The objective of Dr. Geraldine Delbès’ research is to study the impact of environmental compounds and chemotherapy drugs on immature male germ cells and the long-term consequences on adult male fertility. Her research aims to understand how environmental and therapeutic chemicals can affect the programming of male germ cells and have long-term consequences on spermatogenesis. Using in vivo and in vitro models in rodents and humans, her research team studies cellular and molecular responses to endocrine disruptors and anti-cancer drugs, and evaluates epigenome, gene expression, damage to the DNA and oxidative stress.

Her work has involved collaborations with research networks in Canada, Europe and Tunisia and has resulted in more than 25 publications in peer-reviewed journals and books, as well as more than 50 presentations at national and international meetings.
