What is the Origin of Testosterone Neuroprotection?

This concept emerged from neuroendocrinology research, recognizing the presence of androgen receptors in various brain regions, particularly the hippocampus and cortex. The field moved beyond viewing testosterone solely as a reproductive hormone to acknowledging its vital trophic and protective roles in the brain. This expanded understanding has informed modern hormonal therapy protocols.

What is the Mechanism of Testosterone Neuroprotection?

Testosterone exerts its neuroprotective effects through several pathways, including genomic and non-genomic actions. It acts as an antioxidant, reducing reactive oxygen species, and modulates the expression of genes involved in neuronal survival and plasticity. Furthermore, its conversion to estradiol via aromatase provides estrogenic neuroprotection, which is particularly relevant for maintaining cerebral blood flow and synaptic density.

Testosterone Neuroprotection

Meaning

Testosterone Neuroprotection is the biological mechanism by which testosterone, or its active metabolites like dihydrotestosterone and estradiol, shields neuronal cells from damage, oxidative stress, and neurodegenerative processes. This protective effect is crucial for maintaining cognitive function, mood stability, and the structural integrity of the central nervous system throughout the lifespan. Declining testosterone levels are often associated with increased neurological vulnerability.
