ovarian transplant

Researchers printed gelatin scaffolds into which they placed ovarian tissue, and then implanted the new organs in mice. Three out of seven female mice produced healthy offspring using the technology.

Each twin had an ovary removed and frozen in 2009, when they were in their 30s, in hopes of buying more time to get pregnant and have babies. But will the thawed, reimplanted ovaries work?

One-third of women who froze ovarian tissue before undergoing cancer treatment and later had it transplanted back ended up having babies, according to a study of women in Denmark.
