Spontaneous growth in Turner's syndrome.

The natural course of growth in Turner's syndrome is demonstrated on the basis of growth data from untreated patients. The mean adult height was found to be 145.5 cm (range 136-166 cm), the growth curve was similar to that in comparable studies. A decreased growth potency of skeletal (and other) cell populations seems to be the causal defect, beginning with intrauterine growth retardation. Special other causes like metabolic or endocrine changes could be excluded.
