The Y chromosome degrades over time and men's health is paying for it

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a significant role. New research on the topic hints that the human Y chromosome is evolutionarily unstable and could even become extinct in the future.
