title: [Klinefelter's syndrome in 19 year old adolescents. (100 cases detected during selection for National Service)].
abstract: An analysis of 100 cases detected at the age of 19 years during selection for National Service. A somatic, genetic, psychological and hormonal profile emerges from this homogeneous sample. A study of olfactory function and insulin secretion was made. Testosterone deficiency was moderate, DHT deficiency being much more marked and insensitive to stimulation, suggestive of a 5 alpha-reductase defect. Impairment of oestrogenic function of the testis was demonstrated.
