Changes in testosterone levels may contribute to low energy and motivation, low libido, mood changes, physical fatigue, muscle loss, joint pain and urinary complaints.
SHBG stands for sex hormone-binding globulin. It’s a protein that attaches to certain hormones, such as testosterone, and carries them through the bloodstream. When testosterone is attached to SHBG, less of it is available for the body to use, which may result in the symptoms above.
Therefore, measuring testosterone and SHBG together gives your clinician a more useful picture than measuring testosterone alone, because it shows both your total testosterone level and how much may be available for your body to use.
