    Abstract:
    Relationships of endogenous testosterone, androstenedione, dehydroepiandrosterone, estradiol, and progesterone to lipoprotein cholesterol levels were examined concurrently in four groups of children (N = 375, age range 6 to 18 years) whose earlier VLDL-cholesterol and/or LDL-cholesterol levels were in the extreme quintiles or quartiles. In terms of significant correlations, estradiol related inversely with VLDL-cholesterol in prepubertal boys (-0.28) and pubertal girls (-0.34), while estradiol/testosterone ratios related inversely with LDL-cholesterol in pubertal girls (-0.27). HDL-cholesterol related negatively with testosterone in pubertal boys (-0.24) and positively with estradiol in pubertal girls (0.40). With respect to contrasting lipoprotein profiles, high LDL-cholesterol groups had significantly high progesterone/estradiol ratio (boys: 8.6 v 6.9; girls: 8.3 v 5.1), high progesterone (girls only: 0.40 v 0.29 ng/mL) and low estradiol/testosterone ratio (girls: 0.15 v 0.21; prepubertal boys: 0.09 v 0.21). Pubertal girls from high VLDL-cholesterol groups showed markedly low estradiol (71 v 120 pg/mL) and estradiol/testosterone ratio (0.11 v 0.19). These results emphasize the role of endogenous sex hormones in modulating lipoprotein concentrations as well as in the sexual divergence of lipoprotein profiles between males and females following puberty.
