Contribution à l'étude des glandes aréolaires chez la femme : description morphologique, et corrélats fonctionnels dans l'adaptation mère-nouveau-né

Abstract : In human females, the areola concentrates several features potentially related with hemocommunicative functions directed to the suckling infant. Semiochemical significance of the human areolae was examined in different ways: 1) in examining the morphology of areolae in lactating mothers, the areolar distribution of skin glands, and the dynamics of their secretory activity; 2) in relating the amount of areolar glands in individual women to adaptive responses on the infant's side (sucking performance, initial weight gain) and on the mother's side (lactation dynamics); 3) in recording infant responses when exposed to the total effluvium of their isolated mother's areola; 4) in exposing newborn infants to "pure" areolar secretions, and comparing their responses to those elicited by other nursing-related odorants.
Our results allow envisioning human areolar glands as facilitators of breastfeeding interactions in humans, especially in first time mothers. These glands, as well as milk itself, are associated with infant state regulation and directional responses, and with shorter-delay onset of lactation. The odours of the whole breast and of the isolated areola delay crying onset and activate appetitive actions in infants. Finally, pure native secretions from the areolar glands are salient to newborn infants in whom they intensify oro-facial responses and respiratory activation. The above results concur to indicate that the areolar secretions of lactating women are in a position to play a role in establishing mother-infant behavioural and physiological processes pertaining to milk production and transfer.
