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

As humankind moves toward the goal of establishing a long-term presence on the moon and Mars, the question of whether ...

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

Space is big, empty, and apparently very confusing if you’re a sperm cell. According to a new study from the University of ...

A new experimental design that can sustain mouse embryos outside the uterus means that soon, we may be able to watch ...

It’s challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That’s why many mammalian embryos can postpone their growth to get through periods of environmental ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...
