Abstract

Leydig cell hyperplasia is a common histological finding in male infants of diabetic mothers. The functional correlates of this histological finding were investigated by measuring βhCG, testosterone, androstenedione, dihydrotestosterone, and progesterone in mixed cord serum of male and female infants of diabetic mothers (n = 40) and normal mothers (n = 40) at term. Male and female infants of diabetic mothers had significantly higher cord serum =hCG levels than male and female controls. Male infants of diabetic mothers had significantly higher cord serum testosterone concentrations than male controls, female controls, and female infants of diabetic mothers. Cord serum testosterone concentrations were similar in female infants of diabetic mothers and female controls. In the male infants of diabetic mothers, there was a significant positive correlation between βhCG and testosterone (r = 0.64; P < 0.01). There was no significant correlation between jShCG and testosterone in the male controls (r = −0.15; P = NS). There was no significant difference in cord serum dihydrotestosterone in any group tested. Cord serum progesterone was significantly higher in the males than in the females. Cord serum androstenedione was lower in the infants of diabetic mothers than in the controls. This study suggests that the Leydig cell hyperplasia found in male infants of diabetic mothers is due, in part, to elevated concentrations of hCG and is accompanied by elevated testosterone concentrations in the fetal compartment.
