A proposed international legal and ethical definition could address current challenges, with implications for improving IVF success rates. The ethical and legal challenges posed by embryology research ...

Scientists used stem cells to create a model of an embryo in the lab without sperm or egg. The model embryo released the same hormones that trigger positive pregnancy tests. Researchers hope to use ...

A team of scientists in Israel say they’ve created a completely human-like embryo model without the need for a sperm or egg, up through 14 days of development. Reading time 3 minutes A team of ...

The biological and legal definitions of “embryo” don’t match, and that will become a problem, according to Nicolas Rivron, PhD, of the Institute of Molecular Biotechnology of the Austrian Academy of ...

In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

Natural ovulation before frozen embryo transfer is as effective as hormone treatment for achieving a healthy baby by vitro ...

Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

"Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said Dr. Peter Rugg-Gunn, ...
