February 2017 in “European journal of neuroscience/EJN. European journal of neuroscience” This study found that local synthesis of 17β-estradiol and 5α-dihydrotestosterone, combined with specific stimulation patterns, is crucial in determining the direction and strength of long-term synaptic effects in the hippocampal CA1 region of male rat slices.
May 2025 in “Psychopharmacology” In this study, chronic finasteride administration in male rats led to depression- and anxiety-like behaviors only in specific tests and moderately affected hippocampal synaptic plasticity, possibly due to adaptive plasma corticosterone level changes over time.
January 2026 in “Frontiers in Cellular Neuroscience” This study discusses the complex roles and effects of brain-synthesized sex neurosteroids, highlighting sex differences in their concentrations and their varied impacts on synaptic plasticity, cognitive behavior, and aging-related cognitive decline.
April 2024 in “Journal of psychiatric research” This study observed that short-term administration of finasteride in male Wistar rats induced anxiety-like and depression-like behaviors, impaired spatial learning and memory, and reduced synaptic plasticity in the hippocampus, with a trend of increased corticosterone levels noted.
