If you’ve worked with me, you’ve probably heard me talk about epigenetics. Here’s a great explanation…

New research shows that a father’s trauma can physically alter the RNA inside his s***m, creating biological signals that may pass anxiety related traits to his future children. Scientists discovered that stressful experiences change the molecular instructions carried within spe*m, affecting how genes linked to stress response, brain development, and emotional regulation behave in the next generation. These changes do not rewrite DNA, but they modify how the DNA is expressed, shaping a child’s sensitivity to stress before birth.
Researchers observed that offspring of traumatized fathers showed heightened fear responses, increased stress hormones, and stronger reactions to challenging environments. The altered s***m RNA appeared to “prime” the developing brain, making it more reactive to threat. This form of inheritance, known as epigenetic transmission, reveals that emotional experience can leave physical marks on reproductive cells, influencing traits long after the original trauma has passed.
The findings do not mean a child is destined for anxiety, but they highlight how deeply human biology responds to lived experience. Supportive parenting, safe environments, and emotional nurturing can help reshape stress pathways and strengthen resilience, reducing the impact of inherited sensitivity.
This research expands the understanding of how trauma moves through families. It shows that healing is not only personal but generational, and that caring for mental health today may protect the emotional well being of tomorrow’s children.
