[Activity of the hypophyso-gonadal axis in premature boys].

Postnatal evolution of testosterone, LH and FSH plasma levels was studied in 30 premature boys. Increase in LH and testosterone levels at the age of 2 months was found in these children as in full-term children; both parameters were positively correlated. Activation of hypophysogonadal function in premature seems to depend on postnatal age and not on gestational age.
