Air pollution linked to DNA changes in sperm, research shows
A large-scale study of over 2,000 men has linked exposure to common air pollutants like ozone and nitrogen dioxide to epigenetic changes in sperm DNA. These findings suggest that environmental factors may negatively impact male fertility by altering gene expression during sperm development.
Why it matters
Understanding the biological mechanisms linking pollution to reproductive health is critical for public health policy and addressing declining fertility rates.
