Scientists have evaluated the adverse effects of blastocyst shrinkage on the reproductive outcomes of frozen-thawed embryo transfer. The effect was evident in embryos with morphologically ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

The world has now learned of a surprising scientific advance: so-called “synthetic embryos.” Their arrival promises to reveal to medicine previously hidden glimpses into problems of early pregnancy.

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
