protein that regulates sex hormones' availability in the bloodstream
Sex Hormone-Binding Globulin (SHBG) is a protein produced by the liver that binds to sex hormones, such as testosterone and estrogen, in the bloodstream. By binding to these hormones, SHBG regulates their bioavailability and activity in the body, influencing various physiological processes, including hair growth and reproductive functions.
