After the COVID\u201019 pandemic, it became more evident mainly in adolescents. The exposure to stressful situations is strongly related to mental diseases development.

Animals in the stress\u00a0and stress+escitalopram groups were subjected to a CMS protocol consisting of nine randomly applied stressors over 8 weeks (postnatal Days 41\u201397). Escitalopram (10\u00a0mg\/kg\/day) was administered by gavage from postnatal Day 70 for 4 weeks. At adulthood, males were mated with healthy nulliparous females to evaluate reproductive outcomes and offspring development. Testes and epididymides were collected on postnatal Day 114 for the assessment of sperm chromatin protamination and SIRT1 immunoexpression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>CMS and\/or escitalopram treatment reduced sperm chromatin protamination, SIRT1 immunoexpression in the seminiferous epithelium, placental thickness, and increased the frequency of skeletal abnormalities in the offspring.
