It is estimated that parents seeking to have children through in vitro fertilization (IVF) spend between $12,000 and $15,000 each session plus the cost of medications, which could average between $3,000 and $5,000. Now, researchers at the University of Missouri publishing in the Proceedings of the National Academy of Science have made a discovery that could decrease the costs associated with IVF in humans—and it all started with piglets.
