GH-binding protein is related to bone mineral density in non-obese androgenized women.
GH and IGF system components are important regulators of bone formation and at the same time pathogenetic factors in functional hyperandrogenism (FH) in lean females. We studied the relationships between bone mineral density (BMD) and serum concentrations of GH, GH-related parameters, androgens and estrogen, in 18 non-obese women of reproductive age with functional hyperandrogenism compared to a group of 10 healthy eumenorrheic age- and weight-matched women. In androgenized women, a significant positive correlation was found between BMD and GH-binding protein (GHBP), whereas BMD did not correlate to GH or other related parameters. It is suggested that higher tissue GH receptor responsiveness in non-obese androgenized women may contribute to their higher BMD.
