Testosterone circulates almost entirely bound to transport proteins: normally less than 1% is free. Measurement of Free Testosterone may be useful when disturbances in Sex Hormone Binding Globulin (SHBG) are suspected such as when patients are obese or have excessive estrogen. Testosterone measurements are used to assess erectile dysfunction, infertility, gynecomastia, and osteoporosis and to assess hormone replacement therapy.
