Assisted reproduction in humans and animals has been linked to inappropriate control of the epigenome in gametes and preimplantation embryos that results in adverse consequences during fetal and postnatal development. Commonly used assisted reproductive technology (ART) procedures include: ovarian hyperstimulation (superovulation), in vitro maturation, in vitro fertilization, intra-cytoplasmic sperm injection, embryo culture, and embryo transfer. The research conducted in my laboratory aims at understanding the mechanisms whereby manipulations of mammalian gametes and embryos result in alterations of the epigenome. The long term goal of our research is to provide recommendations in order to decrease the negative side effects associated with ART.
