COVID-19 Infection Before Conception Affects Offspring's Brain and Behavior
A new study reveals that a father's COVID-19 infection before conception can alter sperm and impact brain development.
Researchers at the Florey Institute in Australia found that COVID-19 infection in fathers can cause molecular changes in sperm, affecting the brain development and behavior of their offspring.
COVID-19 may have biological effects that extend beyond those directly infected.
Lead researcher Professor Anthony Hannan notes that the findings, based on studies in mice, add to growing evidence that a father's health before conception shapes the long-term well-being of his children.
- The SARS-CoV-2 virus causes molecular changes in sperm passed on to the next generation.
- Earlier research found similar outcomes in male mice exposed to environmental or lifestyle factors before mating, such as an unhealthy diet.
