Serum androsterone levels in children.
Serum androsterone was measured by radioimmunoassay in 79 girls and 80 boys aged between six months to sixteen years. In boys, androsterone levels were found to be low until the age of 12 years and then rapidly increased between the ages of 12-13 years. This increase of serum androsterone in boys seems to be related to the rapid increase of testosterone. On the other hand, in girls the androsterone levels were found to be low until the age of 10 years. However, from this age onwards, although individual values were variable, androsterone levels did not increase as rapidly as in boys but rather gradually with age which appeared to be influenced by the progressive increase of dehydroepiandrosterone (DHEA) in girls.
