Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research ...

The risk of older fathers passing on disease-causing mutations to their children is higher than we thought. Genome sequencing has revealed that among men in their early thirties, around 1 in 50 sperm ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

Scientists in the Netherlands have transformed sperm cells into microscopic robots in a move that could transform the future of fertility. The team from the University of Twente, in the Netherland, ...

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...

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 for those ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Sperm are male reproductive (sex) cells. The word "sperm" can refer to spermatozoon (singular) or spermatozoa (plural). Sperm are tiny cells with an oval-shaped body and a long tail. They measure just ...

Last summer, Alexander McKinnon was always feeling tired. “I would lie on the couch at 2 in the afternoon and fall asleep,” he says. The founder of a biotech startup in Boston, he initially thought it ...

The researchers believe the hemifusome works by creating vesicles, tiny bubble-like structures that surround substances in our cells and move them around. “You can think of vesicles like little ...

The first mice to be created from two fathers, a phenomenon known as androgenesis, have now produced healthy offspring for the first time. Researchers implanted two sperm in an egg with its nucleus ...
