The new world of 3-D printed organs now includes implanted ovary structures that, true to their design, actually ovulate, according to a study by Northwestern University Feinberg School of Medicine and McCormick School of Engineering.

By removing a female mouse’s ovary and replacing it with a bioprosthetic ovary, the mouse was able to not only ovulate but also give birth to healthy pups. The moms were even able to nurse their young.

The bioprosthetic ovaries are constructed of 3-D printed scaffolds that house immature eggs, and have been successful in boosting hormone production and restoring fertility in mice, which was the ultimate goal of the research.

“This research shows these bioprosthetic ovaries have long-term, durable function,” said Teresa K. Woodruff, a reproductive scientist and director of the Women’s Health Research Institute at Feinberg. “Using bioengineering, instead of transplanting from a cadaver, to create organ structures that function and restore the health of that tissue for that person, is the holy grail of bioengineering for regenerative medicine.”

The paper was published today, May 16, in Nature Communications.
