What is the Meaning of SHBG?

SHBG is the clinical acronym for Sex Hormone-Binding Globulin, a glycoprotein primarily synthesized and secreted by the liver that binds to and transports sex steroid hormones, namely testosterone, dihydrotestosterone (DHT), and estradiol, in the bloodstream. SHBG acts as a key regulator of sex hormone bioavailability; hormones bound to SHBG are generally considered biologically inactive and unavailable to target tissues. Its concentration in the blood is a crucial factor in determining the amount of "free" or biologically active hormone available to modulate cellular function.

What is the Origin of SHBG?

The term "Sex Hormone-Binding Globulin" is a descriptive name indicating its chemical nature as a globulin protein that binds to sex hormones. The protein was first isolated and characterized in the late 1960s, initially referred to as testosterone-estrogen binding globulin. The acronym SHBG became the standard nomenclature as its central role in regulating the distribution and action of sex steroids was fully elucidated in clinical endocrinology.

What is the Mechanism of SHBG?

SHBG's primary mechanism is to regulate the distribution and metabolic clearance rate of sex hormones by forming high-affinity, reversible complexes with them. When SHBG levels are high, more sex hormones are bound, resulting in lower levels of free, active hormones, which can lead to symptoms of hormone deficiency despite normal total levels. Conversely, low SHBG levels increase the fraction of free hormones. Its synthesis is modulated by various factors, including thyroid status, insulin levels, and estrogen, which influence the overall hormonal milieu.
