We don't know exactly why men are taller than women on average, but we have some genetic clues. On average, human males tend ...

Researchers mapped Y chromosome loss across thousands of individual cells from human cancers, with disturbing results.

One of the genes located on the Y chromosome, designated UTY, plays a vital role in regulating the immune system. Its absence can lead to dysfunctional immune cells; some may overproduce scar tissue, ...

Scientists have discovered that the Y chromosome, crucial for male development, is gradually disappearing. This loss, occurring in some men's cells ar ...

By the age of 70, about 40% of men have lost the Y chromosome in at least some of their white blood cells. This condition, ...

Scientists are expressing concerns about male reproductive health due to the Y chromosome's genetic material loss, potentially disappearing in 11 million years. A study revealed a sharp decline in ...

Flip open a high-school biology textbook, and the rule seems tidy: two X chromosomes mean girl, and an X paired with a Y means boy. That much smaller Y chromosome carries the SRY gene, which is the ...

Males imprint their DNA by adding methyl modifications to it in a way that alters the activity of genes in order to promote ...

Scientists identified 473 human genes that act as genetic “on/off switches,” shaping disease risk through tissue-specific or ...

Women have slightly longer life expectancy than men, but how does health differ between the two sexes as we get older?

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop.
