An inverted nipple (occasionally invaginated nipple) is a nipple that, instead of pointing outward, is retracted into the breast. In some cases, the nipple will be temporarily protruded if stimulated, but in others, the inversion remains regardless of stimulus. Women and men can have inverted nipples.
Surgery is normally performed as outpatient procedure. The surgery consists of a small incision at the base of the nipple while the nipple is in a protected projected state. Then a gentle spreading of the fibers is performed within the nipple (these fibers are what pulls the nipple inward). woman elects to have this surgery performed on her inverted nipples, it might permanently destroy her capacity to breastfeed.
