Family Trauma Across Generations

Child trauma can skip generations via epigenetic markers, new study shows.

In brief

Child trauma can skip generations via epigenetic markers, new study shows. Child trauma may affect future generations through epigenetic changes in sperm, according to a 2025 study in Molecular Psychiatry. Originally reported by Psychologies.

Child trauma impacts multiple generations

Child trauma affects mental and physical health throughout life, potentially skipping to future generations.

“Les traumatismes vécus durant l'enfance n'ont pas seulement des répercussions sur le moment.”

Epigenetic markers explain trauma transmission

Researchers found trauma can alter sperm cells, creating epigenetic markers that affect future generations.

“Quand on est maltraité, ce sont ces spermatozoïdes qui portent ces marques épigénétiques de la maltraitance.”

Study reveals sperm changes from childhood trauma

Study reveals sperm changes from childhood trauma

Scientists analyzed sperm samples from 55 Finnish men to study molecular markers linked to trauma exposure.

“Les chercheurs ont recruté 55 hommes finlandais, en les sélectionnant en fonction de l'ampleur des difficultés vécues durant leur enfance.”

Trauma affects brain development in offspring

Children of traumatized parents show brain development differences without direct trauma exposure.

“Quand cet homme va lui-même avoir des enfants, on a remarqué que ces derniers présentaient des légères différences de développement de leur cerveau.”

Here's the gist

Child trauma may affect future generations through epigenetic changes in sperm, according to a 2025 study in Molecular Psychiatry.
