[Hypophyso-gonadal function in infancy. From newborn to puberty (author's transl)].
Serum levels of testosterone, follicle stimulating hormone and luteinizing hormone have been measured in 216 healthy children (104 boys and 102 girls) divided in 9 groups from newborn to puberty. Testosterone serum concentrations were significantly higher in boys than in girls during the first 4 months after birth. Testosterone values were highest in 1 to 2 month old boys. Serum concentrations of both FSH and LH changed in different patterns in both sexes. During the first 4 years FSH concentrations were significantly higher in girls than in boys. During the first 4 months, however, LH concentrations were higher in boys than in girls.
