Sex Hormone-Binding Globulin (SHBG)

Sex Hormone-Binding Globulin (SHBG) is a carrier protein that binds to sex hormones, including testosterone and estrogen. This interaction influences the availability of these hormones in the bloodstream. By regulating the distribution and activity of sex hormones, SHBG modulates various physiological functions such as reproductive health, bone density maintenance, and metabolic processes. Fluctuations in SHBG levels can impact hormone-related conditions like polycystic ovary syndrome (PCOS) and androgen-related disorders.
