• A study from the University of Kent reveals that the Y chromosome, responsible for male sex determination, is shrinking, sparking concerns about the potential extinction of males.
• The Y chromosome lacks the benefits of genetic recombination and accumulates damaging genetic mutations over generations, leading to its degeneration.
• Despite attempts at self-preservation, the Y chromosome has disappeared in certain species, and its decline raises questions about the future of human reproduction.
• Assisted technologies may offer alternatives for reproduction, but the natural process may be significantly impacted.
