In a study to be released at the 2016 Endocrine Society meeting in Boston, a team of researchers from Northwestern University will discuss the process by which they 3D printed replacement ovaries for a population of test mice who were then able to conceive, give birth to, and nurse healthy baby mice. The ovaries' structure was printed out of a gelatin into a scaffolding that allowed for the growth of fertilized cells and the eventual development of fully formed, healthy pups. While there is still a long way to go before humans receive ovarian bioprosthetics, that is the end to which the researchers have been working and the next step in realizing this possibility are large animal trials.
