The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, Ludwig-Maximilians-Universitaet (LMU) in Munich researchers argue that bovine embryos might ...

Very few specimens exist that document the first weeks of embryonic development in humans. In some cases, information about a particular stage of development comes from a single specimen. Other ...

Researchers have very limited opportunities to study the earliest stages of human development, but a groundbreaking discovery led by a team in Australia will now provide them with a valuable new model ...

Single-embryo transfer has been recommended to reduce the incidence of multiple gestations when in vitro fertilization is performed in women under 36 years of age. We designed a prospective, ...

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, researchers argue that bovine embryos might well be a better model for early human ...
