Association of sex steroid hormones and new bone formation rate. While there is a significant association of A 17β-estradiol [pmol/l] and new bone formation rate [%] in men (men: regression coefficient (rc) = 0.128, p = 0.020; women: rc = − 0.088, p = 0.246), there is B no significant association of testosterone [nmol/l] and new bone formation rate [%] detectable (men: rc = 0.690, p = 0.110; women: rc = − 11.499, p = 0.257) after adjustment for age, gender and coronal vs. apical site
