The end of men? Experts reveal how the male sex chromosome could one day disappear completely.

Since the dawn of humanity, men have played a vital role in determining the sex of their offspring.

The Y chromosome, carried by roughly half of a man’s sperm, dictates whether a child will be male or female.

If the Y chromosome is present, a child will develop into a boy, whereas a lack of this strand of DNA will result in a girl.
