Fathers infected with SARS-CoV-2 passed anxiety-linked changes to offspring via sperm RNA, study finds.
A study on mice found that fathers infected with SARS-CoV-2 showed lasting changes in sperm RNA linked to brain development, which were passed to offspring and associated with increased anxiety-like behaviors and altered gene activity in the hippocampus.
Researchers say this is the first evidence of such transgenerational effects from a viral infection, likely due to epigenetic changes.
While the findings are from animal research, scientists warn similar impacts in humans could affect millions of children’s mental health, though further study is needed to confirm this.
