most of the testosterone in the blood is bound to a protein called sex hormone binding globulin (shbg). "free" testosterone may be checked when conditions that can increase shbg levels, such as obesity or hyperthyroidism, are present.
The levels of other hormones made by the pituitary gland, such as follicle-stimulating hormone (fsh) and luteinizing hormone (lh), may be checked to see whether a low testosterone level is caused by problems with the testicles or ovaries or the pituitary gland. For more information, see the medical tests luteinizing hormone and follicle-stimulating hormone. A really high level of lh and a low level of testosterone often means that the testicles or ovaries are not working properly. A low lh level and a really low or high testosterone level may mean a problem with the pituitary gland.
