The following article describes the current infancy stage of research into how environmental events affect sperm content.
Yup, you read that correctly.
In this study, the topic was obesity, asking the question: if we are overweight, how does that impact our sperm, and does it result in passing along vulnerabilities to weight gain in our children?
If environmental factors influence which genes traits are active in sperm, this could have pretty large implications regarding mental and behavioral health. Here at SBH, we are especially interested in trauma. Note the rats study and high stress mentioned in the article.
