What is the Origin of Serum Estradiol Levels?

Estradiol, one of the primary estrogens, was first isolated and structurally characterized in the 1930s. The practice of measuring serum levels became standard clinical procedure with the development of sensitive immunoassays and, more recently, mass spectrometry techniques. The term specifically refers to the concentration in the fluid component of the blood after clotting.

What is the Mechanism of Serum Estradiol Levels?

Estradiol is primarily synthesized from testosterone via the aromatase enzyme, predominantly in the ovaries, testes, and adipose tissue. Once secreted, it circulates largely bound to sex hormone-binding globulin (SHBG) and albumin. The measured serum level represents the total concentration, which is an important determinant of the free, biologically active fraction that can bind to intracellular estrogen receptors in target tissues.

Serum Estradiol Levels

Meaning

The quantitative concentration of 17-beta estradiol (E2), the most potent and biologically active form of estrogen, measured in the circulating blood serum. Estradiol is a critical steroid hormone with widespread effects on bone density, cardiovascular health, and neurocognitive function in both sexes. Clinical measurement of these levels is essential for diagnosing reproductive and endocrine disorders.
