In 2006, Medela announced the results of research that overturned 160 years of conventional wisdom concerning the female breast. This has important implications for women.
What has changed?
Their findings overturned a number of commonly accepted conclusions. The new picture of the anatomy of the breast revealed changes in the way the breast should be cared for, especially during surgery. It will help breastfeeding mothers gain a better understanding of the way their breasts work, to the benefit of their health and that of their babies.
Among many new insights, Dr. Geddes found that the number of milk ducts in the breast is lower than previously believed. Breast augmentation surgeons will have to take this into account, since the loss of only a few ducts can seriously compromise a woman’s ability to breastfeed.
Our understanding of the way in which the breast produces and delivers milk has also changed. The currently accepted model includes lactiferous sinuses, which were believed to store milk. It turns out that these do not exist.
Because of the uneven distribution of milk glands, the absence of lactiferous sinuses, and the high variability in the number of milk ducts, mothers need to consider their own particular anatomy when deciding how to use their hands to support their breasts during breastfeeding or manual expression. The studies also show that a rapid first milk ejection is important for efficient milk removal and that it is crucial to choose breastshields of the correct size.

“The benefits of breastfeeding are ever more evident and more women are wanting to breastfeed their babies. But breastfeeding can be a difficult process. That is why this research is so important. It will help women and their carers understand their breasts better and thus facilitate their breastfeeding attempts. And it will help those who need breast surgery ensure that their surgeons do not inadvertently put their ability to breastfeed at higher risk than necessary”.
