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

Microgravity is disorienting, even for sperm cells. Some of the world’s wealthiest and most influential people remain deadset ...

It could be more difficult to have a baby in space because sperm could get lost, a new study has warned. Research suggests that sperm’s navigation may be confused by the lack of gravity and therefore ...

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

Researchers found that microgravity impairs sperm navigation without affecting speed, reducing fertilization rates and ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...

The United States’ announcement of building a residential base on the Moon within 10 years has drawn attention, amid research suggesting that human settlement in space across generations may be ...

(BOSTON) — More than one-sixth of adults around the world experience infertility in their lifetime. There is a high unmet need not only for increased access to affordable, high-quality fertility care ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...
