What is the Origin of Vitamin D and Androgens?

This term stems from the convergence of nutritional endocrinology and reproductive physiology, following the discovery of VDR expression in androgen-responsive tissues. It signifies a recognized area of study regarding hormonal co-regulation.

What is the Mechanism of Vitamin D and Androgens?

Vitamin D acts as a prohormone, and its active form, calcitriol, binds to the VDR, which functions as a ligand-activated transcription factor. In Leydig cells of the testes, VDR activation may influence the steroidogenic enzymes necessary for testosterone synthesis, potentially explaining the observed correlation between Vitamin D status and circulating androgen levels. Furthermore, androgens may influence VDR expression in target tissues, creating a complex feedback loop that links these two critical hormonal systems.

Vitamin D and Androgens

Meaning

Vitamin D and Androgens describes the clinically relevant bidirectional relationship between the fat-soluble secosteroid Vitamin D and male sex hormones, such as testosterone and dihydrotestosterone (DHT). Research indicates that optimal Vitamin D status is correlated with healthy androgen levels, and conversely, androgens can modulate the expression of the Vitamin D receptor (VDR). This endocrine interplay is significant for musculoskeletal health, immune function, and reproductive well-being in both sexes.
