A new study found that microgravity simulated on Earth hindered sperm cell movement, egg fertilization and embryo development ...

Getting to Mars is difficult. Conceiving a child there could be even tougher than expected. A recent study led by researchers from University of Adelaide has demonstrated that simulated microgravity ...

"This is the first time we have been able to show that gravity is an important factor in sperm’s ability to navigate through ...

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational ...

Learn how microgravity could affect sperm, fertilization, and embryonic development in space.

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that occur before birth and why many pregnancies fail. These models are made from ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...
