For now, that goal remains elusive. The lab-grown cells stopped developing at an immature stage. Many hurdles need to be ...

Lab-grown sperm could soon become a reality after scientists were able to create germ cells, the precursor to reproductive cells.

A new study has investigated whether air pollution may affect men’s sperm cells.

Reports of falling sperm counts and testosterone levels have fuelled fears over chemicals, pollution and modern lifestyles. But how much do scientists agree on what is affecting male fertility?

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 ...

A novel screening system developed at Kyoto University enables researchers to investigate sperm cell development and health at the molecular level. The new approach, published in Cell Genomics, ...

Researchers have decoded a long-standing mystery of how flowering plants ensure their sperm cells successfully reach the egg for fertilization, according to a recent study published in the journal ...

A colony of human embryonic stem cells is seen on a computer monitor at the University of Wisconsin–MadisonDarren Hauck / Getty Researchers at Newcastle University in England report they have coaxed ...

Sperm swims up a chemical gradient to reach the eggiStock In a recent discovery, scientists have identified a key molecule that drives chemo attraction between sperm and egg cells in marine ...

Among all the animals on Earth, tiny fruit flies produce some of the longest male reproductive cells, or sperm. Males of the species that typically swarms your indoor trash, Drosophila melanogaster, ...
