A team of researchers from the McCormick School of Engineering at Northwestern University in the United States has reported that it has managed to construct the structure of an artificial ovary 3D  (see HERE) a hydrogel that, once transplanted in an animal, can interact with its tissues and create a functioning ovary. This artificial scaffold was implanted in sterilized female mice, with cell division to ovulation taking place in two months. After mating, these females became pregnant and gave birth to healthy mice that survived, after being nursed by their mothers. This is undoubtedly a great technological breakthrough with visions of being used in humans to resolve infertility issues (see HERE).
