Y Chromosome Loss Worsens Health in Men
Scientists have found that the Y chromosome is disappearing in some men, leading to significant health issues. This genetic decline is linked to increased cancer risks and weakened immune responses, sparking new research into its implications and potential treatments.
The Impact on Cancer
Recent studies reveal that the loss of the Y chromosome in cells can significantly worsen cancer outcomes. The absence of this chromosome is linked to a higher risk of the disease and poorer survival rates. This chromosomal change appears to cripple immune cells, diminishing their ability to combat cancer.

“Cells with LOY may induce LOY in otherwise healthy cells—a finding that could explain variability in CAR T-cell therapy response.”

The prevalence of Y chromosome loss (LOY) in men increases with age; over 40% of men aged 70 have some degree of LOY in their blood cells (National Institutes of Health, 2018).
Immune System Weakness
The loss of the Y chromosome “cripples” immune cells. This genetic deficiency hinders the immune system’s ability to identify and eliminate cancerous cells effectively. Research also indicates that LOY can induce similar genetic losses in healthy cells, potentially complicating treatments like CAR T-cell therapy.
Ongoing investigations aim to understand the precise mechanisms behind Y chromosome loss and how it affects health. Scientists are exploring potential therapeutic interventions to mitigate these impacts, hoping to improve outcomes for men facing cancer and other diseases associated with this genetic change.
