Inverted Nipples: A Comprehensive Guide

Inverted nipples, a condition characterized by the inward retraction of the nipple rather than its outward projection, represent a unique concern that can affect both men and women. This condition, which can be present at birth (congenital) or develop later in life (acquired), manifests in varying degrees, ranging from a subtle inward pull to complete retraction against the breast tissue. In some instances, only one nipple may be affected, known as unilateral inversion.

Beyond the aesthetic considerations, inverted nipples can lead to discomfort, complicate breastfeeding, and cause significant self-consciousness in individuals. For those seeking to address this condition, inverted nipple correction surgery may be a solution. This procedure, performed under local anesthesia, corrects the inversion of the nipple and enhance its prominence.

What Causes Inverted Nipples?

The presence of flat or inverted nipples can be attributed to various factors, each shedding light on the multifaceted nature of this condition. These potential causes encompass:

1. Fetal Development

The formation of your nipples dates back to your fetal development stage. If your nipple base is comparatively small or your milk ducts did not fully develop during this critical phase, it can result in the appearance of flat or inverted nipples.

2. Breast Injuries

Incidents such as breast surgery or breastfeeding can lead to tissue scarring within the breast. Such scarring can alter your nipple tissue and lead to inverted nipples.

3. Infections

Bacterial infections can infiltrate the nipple, potentially leading to abscess formation or mammary duct ectasia, where milk ducts may become obstructed. These infections can consequently result in the development of inverted nipples.

4. Age-Related Breast Changes

The aging process brings about changes in the breasts. As menopause approaches, the milk ducts may undergo shortening, resulting in the inversion or flattening of nipples.

5. Pregnancy and lactation

Although relatively uncommon, significant changes in the breast and nipple-areolar tissue during pregnancy and lactation have been reported to result in nipple inversion.

6. Breast Cancer

Breast tumours that infiltrate milk ducts, it can exert pressure on the duct, leading to the flattening or inversion of the nipple.

Investigations for inverted nipples

A thorough review of the individual's medical history and a detailed medical examination provide valuable information for the etiology and stage of the inverted nipples. Breast imagings are often performed before contemplating surgery to rule out malignancy.

The three grades of inverted nipples

Grading the severity of inverted nipples on a scale from 1 to 3 can provide a clear understanding of the condition:

- Grade 1: The nipple can be pulled out manually but may retract again after a while.

- Grade 2: The nipple can be pulled out manually but retracts immediately.

- Grade 3: The nipple cannot be pulled out manually.

Surgery for inverted nipples

Inverted nipple correction surgery is usually conducted in an out-patient setting under local anesthesia. Typically completed within an hour, this surgery has relatively little downtime.

While the exact surgical approach is determined on an individual basis, generally speaking the surgeon makes an incision around the base of the inverted nipple to detach the tethering ducts to allow the nipples to protrude. The detachment of the tethering tissue may potentially interfere with your breastfeeding capability, so it is crucial to discuss the breastfeeding aspects with your surgeon before the surgery. The specific surgical approach employed is tailored to your individual circumstances and certain techniques have greater chances of preserving breastfeeding capability.


Inverted nipples can cause significant psychological stress and lactation difficulty. While surgical correction is a viable solution, it is essential to acknowledge the inherent risks and variable recovery times associated with these procedures. Consultation with a board-certified plastic surgeon is paramount for comprehensive comprehension of the surgical process, potential advantages, risks, and recovery expectations.
