Levels of testosterone that is bound to proteins (albumin and sex hormone-binding globulin—SHBG) plus levels of testosterone that is not bound to proteins (free testosterone) are measured. Testosterone production is stimulated and controlled by luteinizing hormone (LH), which is produced by the pituitary gland (pituitary gland), in a negative feedback loop—when testosterone levels are high, luteinizing hormone production decreases.
