Estradiol in Men

Meaning

Estradiol in Men refers to the natural presence and critical physiological role of the primary female sex hormone, E2, within the male endocrine system. While present at significantly lower concentrations than in women, estradiol is essential for maintaining optimal male health, contributing significantly to robust bone density, vital cardiovascular protection, clear cognitive function, and the necessary modulation of libido. Clinically, maintaining estradiol within a narrow, precise optimal range is crucial, as both pathologically low and excessively high levels can lead to adverse symptoms, particularly in men undergoing testosterone replacement therapy. It is a critical, yet frequently overlooked, biomarker in comprehensive male hormonal assessment.
