Studies of anabolic steroids. VI. Effect of prolonged administration of oxandrolone on growth in children and adolescents with gonadal dysgenesis.

Twenty-five patients with Turner Syndrome were treated with oxandrolone for six or more months. Mean growth velocity for the first year of treatment was significantly greater than pretreatment control growth velocity. Overall, there was no excessive skeletal maturation. Mean "final" height in nine XO patients (146.4 cm) was significantly greater than mean adult height of an estrogen-treated control group (140.3 cm), while that for five mosaic patients (148.2 cm) was not significantly different from a mean untreated mosaic adult height (145.2 cm).
