In order to evaluate the galactopoietic response to rhGH in mothers of normal babies with idiopathic lactation insufficiency arising in the early postpartum period, we performed a preliminary, randomised, single blind trial of 3 different doses of hGH: either 0.05, 0.1, or 0.2 IU/kg/day to a maximum of 16 IU/day, for 7 days. Total 24-hour milk production was determined in each mother 1 day prior to initiating therapy and on the last day of therapy. Milk production rose by 36.0 ± 12.6% in the group receiving 0.2 IU/kg/day (n = 6) but by only 4.7 ± 9.7%, (p < 0.04) in the combined lower dose group (n = 10). In conclusion, these data suggest that moderate dose hGH therapy in mothers with lactation insufficiency can improve galactopoiesis.
