Murine models have been widely used to study aging and age\u2010related cognitive decline, as they recapitulate many of the key features of the degenerative process. Among these, the SAMP8 strain represents a well\u2010established model of accelerated aging, characterized by early\u2010onset and progressive cognitive impairment, Alzheimer's disease\u2010like neuropathology, and an initial increase in hippocampal neurogenesis that ultimately depletes the neural stem cell pool. Notably, most studies using murine models of aging or neurodegeneration have focused on males or mixed\u2010sex cohorts, leaving sex\u2010specific differences in neurogenesis and cognitive decline largely unexplored. Recent evidence indicates that diterpenoid treatment is associated with improved cognitive performance and enhanced neurogenesis in 6\u2010month\u2010old male SAMP8 mice. However, whether females exhibit similar responses remains unknown. In this study, we characterized sex differences in hippocampal neurogenesis in 6\u2010month\u2010old SAMP8 mice and examined potential sex\u2010dependent effects of diterpenoid therapy. Our findings reveal sex\u2010specific differences in physiological and pathological hippocampal neurogenesis and in responsiveness to ER272 treatment. Male SAMR1 mice displayed higher baseline neurogenesis than females, while male and female SAMP8 mice followed distinct neurogenic aging trajectories. ER272 was associated with improved cognitive performance and preservation of multiple neurogenic parameters in males but showed limited effects in females. These results suggest sex\u2010specific mechanisms of brain aging and indicate that mixed\u2010sex analyses may mask biologically relevant differences, highlighting the importance of considering sex in aging studies and therapeutic development.<\/jats:p>","DOI":"10.1111\/acel.70663","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T14:03:07Z","timestamp":1791554587000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sex\u2010Specific
