Uterine peristalsis is a normal part of the uterus’s activity during the menstrual cycle. In this guide, we explain how these ...

A new study shows that the embryo and the uterine lining conduct an active "conversation" from the very earliest stages of implantation. They engage in a back and forth of tiny packages called ...

Implantation is the initial step in pregnancy, where the embryo attaches to and enters the endometrium, the inner tissue layer of the uterus. During this process, the cells of the endometrium change ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Stem cell-derived embryo models offer scientists a promising way to investigate the earliest stages of human development, but ...

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while these technologies successfully create viable embryos, a little over half of ...

Researchers generated mouse embryo models entirely from chemically induced totipotent-like stem cells that self-organized ...

New research has demonstrated the effectiveness of a first-in-class oral, non-hormonal drug in increasing embryo implantation, pregnancy and live birth rates among infertile women who are undergoing ...

The use of a precise gene editing technique to edit human embryos has caught the attention of academics and society, yet ...

University of Sydney researchers have developed a new way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well, none yet fully ...
