The Effects of Hormones in Growth Hormone-Treated Girls With Turner Syndrome

Turner syndrome is associated with short stature, multiple physical stigmata, and absent pubertal development. We propose to: (1) examine the effects of sex steroids (androgen) on multiple variables (growth rate, GH binding protein, IGF-I, and cognitive function), in the setting of supplemental growth hormone administration and (2) to investigate any synergistic or additive effects of the androgen and estrogen combination on the above variables.
