Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...

Somewhere on the short arm of the ninth chromosome, there lies a locus, or loci, that can cause amyotrophic lateral sclerosis (ALS) or frontotemporal lobar dementia (FTLD). A portion of the petit (p) ...
