However, it's important to note that this field of research is still in its infancy. Seeing epigenetic changes in sperm does not necessarily mean these changes are passed on to children. In fact, researchers are working very hard to answer that question, Tuulari said.

It has not been confirmed that epigenetic changes can be passed from a human parent to their children, he said. "It has been shown, however, in experimental animal models, including worms and mice."

Therefore, it is too soon to draw any conclusions about the influence of paternal stress on a child's health, Tuulari said. It is also not clear whether the epigenetic changes observed would ultimately have a positive, negative or neutral effect, he added.

Very interesting stuff. I'll have to look out for future studies.
