Hypophyso-gonadal function in the diabetic child.
14 diabetic boys (five with a family history of diabetes and nine without) and 29 "short normal" boys were studied. A gonadal function test (2.000 IU of hCG i.m. for 3 days and plasma testosterone assay before and after the hCG administration) as well as an LH-RH test (50 microgram i.v.) were carried out. While basal testosterone level turned out to be similar in the two groups of children, it was significantly lower (p less than 0.01) after hCG than the mean value of the control group. This difference was mainly observed in those patients with a family history of diabetes. In the diabetic children, basal LH level was normal and the pituitary LH reserve was lower than in the control group. Both basal FSH level and FSH pituitary reserve were lower than in normal children. These data show that an alteration in the hypothalamus-pituitary-gonadal function is already evident in the diabetic child.
