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 around age 50, is linked to increased risks of ...

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, ...

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 ...

This means that doctors should weigh the Y chromosome status of a patient’s cancer before deciding on treatment options that leverage the immune system, he elaborated, such as autologous CAR-T ...

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

We're a step closer to two men being able to have genetic children of their own after the creation of fertile mice by putting ...
