It is my hypothesis that "prematurity" or "small for gestational age"
results from low maternal DHEA. The mother produces DHEA for herself and
her fetus; any shortages of DHEA will adversely affect fetal growth and
development.
While I cannot find much regarding DHEA in breast milk in the
literature, it is clear that prolactin is provided in breast milk.
Prolactin has been demonstrated to be a specific stimulator of DHEA. I
suggest it is this prolactin in breast milk which is so beneficial to
nursing infants. This will hold true except in infants who cannot produce
sufficient DHEA for growth and development on their own or stimulated by
mother's milk. If one wishes to make formula more beneficial to infants,
I suggest supplementation with prolactin or DHEA.
