How do female nipples form?

Women pay special attention to the image of their breasts. They not only want their breasts to be firm and full, but also their nipples to be firm. This can better reflect the sexy beauty of women's breasts. However, some women have inverted nipples due to various reasons, which makes many women very worried. The following introduces how inverted nipples of women are formed? You can have a comprehensive understanding.

1. The main causes of primary nipple inversion

1. Hypoplasia of the smooth muscles of the nipple and areola: The nipple has the opening of the lactiferous duct and smooth muscle fibers around the lactiferous duct. The inverted nipple is pulled inward by the muscle fiber bundles surrounding the lactiferous duct and inserted into the nipple dermis. The texture of these muscle bundles is significantly different from that of the lactiferous ducts.

2. The lactiferous ducts themselves are underdeveloped: the underdeveloped lactiferous ducts fail to become ductalized and appear as cords.

3. The lack of supporting tissue under the nipple is also a cause of inverted nipple.

Second, the main causes of secondary nipple inversion

Secondary nipple inversion (acquired nipple inversion) deformity is relatively rare. It is caused by the nipple being pulled by pathological tissue in the breast or by unreasonable breast binding or wearing a bra that is too tight. It is often caused by diseases such as inflammation and tumors, which invade the ducts, ligaments, and fascia of the breast, causing the invaded ducts, ligaments, and fascia to contract. Unreasonable breast binding or wearing too tight bras occurs in adolescence. Due to tight breasts and poor blood circulation, it causes breast hypoplasia and leads to acquired inverted nipples.

In acquired nipple inversion, infection is one of the main factors causing nipple inversion. Mainly, mammary duct inflammation accompanied by fibrosis, scar contracture affects its normal development and causes nipple inversion.

Inverted nipples may occur in cases of breast malignancy, but the significance of this nipple deformity is different. If women with normal breasts develop inverted nipples without obvious causes, they should undergo mammograms and other examinations to help diagnose such cases.

Breast surgery can also cause a nipple deformity called inverted nipple. When using the dermal pedicle in breast reduction surgery, nipple inversion may also occur due to tension and scar contraction.

There are many reasons for female inverted breasts, such as congenital and acquired. Congenital ones are generally unpreventable, but acquired ones can be prevented by doing a good job of prevention. For example, when wearing underwear, you must pay attention to wearing loose underwear. And when the nipple becomes inflamed, you must seek treatment as soon as possible to better avoid inverted nipples.
