In humans, areolar skin glands (AG) enlarge during pregnancy and lactation. Their role in mother-infant interactions may pertain to protective, mechanical, and communicative functions. It was questioned here whether more profuse AG could be related to more optimal adaptation to breastfeeding. A morphological study of the areolae was undertaken between birth and day 3 to assess the number, secretory status, and spatial distribution of AG. These data were related to infants' weight variation, mothers' perception of their infant's behavior at breast, and time between delivery and onset of lactation. AG were seen in virtually all women but with great interindividual variations; their areolar distribution was nonrandom, and about 1/5 of the women had AG giving off a secretion. The AG number was positively related with neonatal weight gain between birth and day 3, and with the mother's perception of infant's latching speed and sucking activity. AG numbers were also positively related with the onset of lactation in first-time mothers. In conclusion, the maternal endowment in AG may contribute to the infants' breastfeeding performance, early growth, and the mother's lactation onset.
在人类中，乳晕皮肤腺（AG）在怀孕和哺乳期会增大。它们在母婴互动中的作用可能与保护、机械和交流功能有关。这里有人质疑，更丰富的乳晕皮肤腺是否与对母乳喂养的更优适应有关。在出生至第3天期间对乳晕进行了形态学研究，以评估乳晕皮肤腺的数量、分泌状态和空间分布。这些数据与婴儿体重变化、母亲对婴儿在乳房处行为的感知以及分娩至泌乳开始的时间有关。几乎在所有女性中都能看到乳晕皮肤腺，但个体差异很大；它们在乳晕的分布并非随机，约五分之一的女性乳晕皮肤腺会分泌物质。乳晕皮肤腺的数量与出生至第3天新生儿体重增加呈正相关，也与母亲对婴儿含接速度和吸吮活动的感知呈正相关。乳晕皮肤腺数量还与初产妇泌乳开始呈正相关。总之，母亲乳晕皮肤腺的先天条件可能有助于婴儿的母乳喂养表现、早期生长以及母亲泌乳的开始。
