Sex Hormone

Binding Globulin Sex Hormone Binding Globulin (SHBG) is a glycoprotein produced in the liver that binds to sex hormones such as testosterone, estradiol, and dihydrotestosterone (DHT). Its main function is to regulate the level of these hormones in the blood, allowing them to enter and leave cells in order to perform their functions. SHBG is important for many bodily processes including sexual development, fertility, muscle growth, and energy levels. Low SHBG levels are associated with a number of health issues including obesity, diabetes, hypothyroidism, and hormonal imbalances. Elevated levels also have been linked to certain medical conditions. It is possible to measure SHBG levels through a laboratory blood test. The results of this test can help diagnose and treat conditions caused by abnormal hormone levels.
