Inverted nipples: grades, causes and correction

What are inverted nipples?

Inverted nipples are nipples that retract into the areola rather than projecting outwards. They can affect one or both breasts, in women and in men. In most people the cause is congenital: the milk ducts are short or the fibrous bands beneath the nipple are tight, pulling it inwards. Inversion may be constant or only some of the time – for example, the nipple may come out with cold or touch and then retract again.

A related term, "retracted" nipple, often describes a nipple that is only partly pulled in or has a slit-like appearance. Doctors look at the whole picture rather than the name.

Grades of nipple inversion

• Grade 1: the nipple can be pulled out easily with the fingers and stays out for a while. The ducts are usually normal, and breastfeeding is generally possible.
• Grade 2: the nipple can be pulled out, but with more difficulty, and it soon goes back in. There is some fibrosis beneath the nipple and the ducts are mildly shortened.
• Grade 3: the nipple is severely inverted and can hardly or not at all be pulled out. The ducts are short and tight, and fibrous tissue holds the nipple in. Hygiene problems and irritation can occur.

The grade determines which technique is used and how likely it is that breastfeeding can be preserved.

Causes – and when to see a doctor

Lifelong inversion is usually congenital. Acquired inversion – a nipple that was normal and becomes inverted – can be caused by:

• breastfeeding, scarring or previous infection (such as a breast abscess);
• duct ectasia, a benign widening of the ducts near the nipple that is more common around the menopause;
• previous breast surgery, including breast reduction;
• significant weight loss or sagging;
• less commonly, an underlying breast cancer pulling on the tissue.

A nipple that has newly turned inwards, especially on one side, should always be examined by a doctor promptly, together with imaging when appropriate. Read more about warning signs on our page about breast cancer symptoms. Correction surgery is only planned once any underlying cause has been excluded.

Non-surgical methods

For grade 1 inversion, suction devices (nipple "shapers" or retractors) worn for a few hours a day over weeks can sometimes stretch the tissues and help the nipple stay out. Results are variable and often temporary. Nipple piercing is used by some people to hold the nipple out, but it carries a risk of infection and duct damage and is not a medical treatment. Fillers are not a reliable long-term solution.

Inverted nipple correction surgery

Surgical correction is a short procedure, typically 30 to 60 minutes for both sides, usually done under local anaesthetic, sometimes with light sedation. Through a tiny incision at the base of the nipple, the surgeon releases the tight fibrous bands that pull it in. A small purse-string stitch and/or small flaps of local tissue are used to support the nipple from below and prevent it from retracting again.

• Duct-sparing techniques release the fibrous bands while preserving the ducts. They are used mainly for grade 1 and 2 and give the best chance of being able to breastfeed later.
• Duct-dividing techniques divide the shortened ducts. They are more reliable for severe grade 3 inversion but make breastfeeding from that nipple unlikely.

The scars are tiny and usually almost invisible once healed. Correction can be combined with an areola reduction, a breast lift or breast augmentation.

Recovery and results

Most people go home the same day. A protective dressing or small shield keeps pressure off the nipple for one to two weeks. Mild soreness and swelling settle within days; you can usually return to work after one or two days and to the gym after two to three weeks. Stitches are typically removed or dissolve within about two weeks.

Possible risks include temporary or permanent changes in nipple sensation, recurrence of inversion (more likely in grade 3), small wound-healing problems and, with duct division, loss of breastfeeding on that side. Asymmetry between the two nipples can occur. Your surgeon will explain your individual risk.

Breastfeeding considerations

Many women with grade 1 or 2 inverted nipples breastfeed successfully, sometimes with help from breast shields or a lactation consultant. If you are planning a pregnancy, tell your surgeon: a duct-sparing technique is preferred, and some women choose to wait until after they have finished breastfeeding. Our page on breastfeeding after breast surgery explains more.

Inverted nipples in men

Men can also have inverted nipples, sometimes together with gynecomastia. The same procedure under local anaesthetic is used, and it can be combined with gynecomastia surgery. As in women, any newly inverted nipple in a man should be checked by a doctor before cosmetic correction.
