SHBG

Sex Hormone Binding Globulin (SHBG) is a key protein produced mainly by your liver that manages how much testosterone and other sex hormones are actually "free" and available for your body's tissues to use. Measuring your SHBG level can provide critical insight, especially when a total testosterone result doesn't quite explain your symptoms. For men, this test is often used when low libido or erectile dysfunction are present; for women, it helps evaluate symptoms of excess male hormones like excess hair growth or irregular periods, often linked to conditions like PCOS.
