US EditionCovid virus changes sperm in mice, may raise anxiety in offspring: study
Study shows Covid-19 alters molecules in male mice sperm, increasing anxiety and changing brain gene activity in their offspring, suggesting possible long-term generational effects.
- On Saturday, researchers at the Florey Institute in Melbourne infected male mice, mated them with female mice, and found Covid-19 altered sperm, raising anxiety in their offspring.
- The Covid pandemic's scale, including more than seven million deaths, prompted Florey Institute researchers to show a father's SARS-CoV-2 infection before conception may alter offspring brain development.
- Analysis of sperm RNA showed COVID-19 altered molecules regulating genes important in brain development, while female offspring displayed significant gene-activity changes in the hippocampus, researchers said.
- Researchers cautioned that more work is needed to assess human relevance, while lead researcher Anthony Hannan said `These findings suggest that the Covid-19 pandemic could have long-lasting effects on future generations`.
- Researchers let male mice recover for a few weeks before mating to isolate preconception infection effects, while Carolina Gubert said brain changes may raise offspring anxiety via epigenetic inheritance.

Covid virus changes sperm in mice, may raise anxiety in offspring: study
Covid-19 infection causes changes to sperm in mice that may increase anxiety in their offspring, a study released Saturday said, suggesting the pandemic's possibly long-lasting effects on future generations.
Australian scientists found that the virus could alter sperm and transmit greater anxiety to offspring. The study raises questions about the effects of covid in future generations.
Covid-19 infection causes alterations in the sperm of mice that could increase anxiety in their offspring, suggesting possible lasting effects of the disease in future generations, revealed a study published on Saturday.For research, researchers from the Florey Institute of Neuroscience and Mental Health in Melbourne, Australia, infected male mice with the virus that causes the covid, crossed them with females and evaluated their impacts on the …
