Increased stress on fathers leads to brain development changes in offspring

New research in mice has found that a father’s stress affects the brain development of his offspring. This stress changes the father’s sperm, which can then alter the brain development of the child. This new research provides a much better understanding of the key role that fathers play in the brain development of offspring.

Scientists have known that a mother’s environment during pregnancy, including factors such as poor diet, stress or infection, can cause damage negatively impact her offspring. This may be due in part to how this environment affects the expression of certain genes — known as epigenetics.

But the researchers, led by neuroscientist Tracy Bale at the University of Maryland School of Medicine, now show that a father’s stress can also affect offspring development, by altering important aspects of his sperm.
