Testosterone Concentrations

Meaning

Testosterone concentrations refer to the measurable amount of the primary male androgen circulating in the bloodstream, typically quantified as total testosterone (bound and unbound) and free testosterone (biologically active). These concentrations are a critical biomarker of endocrine health in both men and women, reflecting the secretory output of the gonads and adrenal glands. Optimal concentrations are essential for maintaining muscle mass, bone density, libido, and cognitive function.
