From: SHBG and total testosterone levels in men with adult onset hypogonadism: what are we overlooking?
Relationship between the plasma levels of SHBG and total testosterone among men presenting for evaluation of AOH (a) and a cohort of men who were being treated with a transdermal testosterone preparation (b). In a, testosterone = 77.532 + (8.709 * SHBG), r = 0.71, p < 0.01, and in b) testosterone = 371.209 + (2.023 * SHBG); r = 0.1, p = 0.16
