Researchers at Oregon Health & Science University (OHSU) recently reported a striking first: They created human eggs in the lab using skin cells and then fertilized those lab-derived eggs with human ...

It's a commonly held belief: Sperm cells are like runners in an epic race, competing against each other for access to the coveted egg at the finish line. The egg, in turn, waits patiently for the ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

Katsuhiko Hayashi pulls a clear plastic dish from an incubator and slides it under a microscope. "You really want to see the actual cells, right?" Hayashi asks as he motions toward the microscope.

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 ...

A new study identifies the defective function of CatSper, an ion channel controlling calcium levels in sperm, as a common cause of seemingly unexplained male infertility. CatSper-deficient human sperm ...

An engineering team says that their sperm-injecting robot was the first robot ever to successfully fertilize a human egg. What's more, that robot is controlled in part by a piece of tech you might ...

Early lab work shows reprogrammed skin cells can yield embryos, hinting at future infertility solutions but raising safety questions that demand more study. Infertility affects millions of people ...
