Recent studies connect Y chromosome loss with several serious health conditions. These include heart disease, brain disorders ...

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

For years, we’ve been taught that men have one X and one Y chromosome, with the Y carrying the vital gene that initiates male development. But now, scientists are sounding the alarm: the Y chromosome ...
