What is the Origin of Neuro-Androgen Signaling?

This specialized term originates from neuroendocrinology, recognizing that the brain is a primary target organ for androgens, not just a regulator of their peripheral production. The integration of "Neuro" and "Androgen" emphasizes the systemic nature of hormonal influence across both endocrine and nervous systems.

What is the Mechanism of Neuro-Androgen Signaling?

Androgens cross the blood-brain barrier and act via intracellular androgen receptors located in various brain regions, including the hippocampus and cortex, influencing neurotransmitter synthesis and dendritic arborization. They also undergo local aromatization into estrogens within specific neuronal populations, which then exert neuroprotective and modulatory effects, demonstrating a delicate interplay that is essential for maintaining cognitive reserve.

Neuro-Androgen Signaling

Meaning

Neuro-androgen signaling describes the complex, bidirectional communication and influence between the central nervous system and androgen hormones, such as testosterone and dihydrotestosterone. This signaling pathway is crucial for regulating mood, cognition, neurogenesis, and overall brain health, demonstrating the profound non-reproductive roles of androgens in the male and female brain. Dysregulation in this axis can contribute to symptoms of fatigue, depression, and cognitive decline, highlighting its importance in neurological and endocrine wellness.
