Introduction
When Darine El-Chaar began her residency in obstetrics and gynecology at the University of Ottawa five years ago, she grew curious about the potential health repercussions of assisted reproductive technologies (ART), the catchall term for procedures used to help couples artificially conceive a child. ART involves surgically removing eggs from a woman's ovaries, combining them with sperm in the laboratory, and returning them to the womb. Women undergoing ART take "fertility drugs" such as clomiphene citrate and gonadotropins to stimulate the production of many eggs rather than the single egg that would normally grow during their monthly menstrual cycle.
El-Chaar wondered about the influence that ART procedures, as well as the underlying infertility itself, might have on the health of children conceived. She is one of many researchers working to answer the fundamental question of whether introducing fertility drugs and manipulating eggs and sperm in a laboratory setting—in essence, altering the primal environment—sets the stage for adverse health effects in children.
Although some research indicates such a risk exists, there haven't been enough large-scale studies to ascertain if the potential effects are severe enough over the long term to deter couples from seeking infertility treatments. Meanwhile, some findings are pointing the way toward possible refinements to improve health outcomes for ART babies.
