Gynecomastia Causes, Symptoms, and Treatment

Gynecomastia is a condition that causes excessive breast growth in men and in this article, we learn about Gynecomastia causes symptoms, and treatment. The issue can affect one breast or both simultaneously. When it does affect both sides, one side may be more severe than the other, leading to vast differences in symmetry.

The condition can affect boys and men at various stages of their life and can have devastating effects on the sufferer’s self-esteem.

While gynecomastia isn’t considered a serious problem, it is best to consult with a gynecomastia surgeon for an accurate diagnosis. Getting diagnosed with gynecomastia can rule out more serious problems, like male breast cancer.

Gynecomastia Symptoms may go away on its own, but if it persists, there are treatments, including gynecomastia surgery.

What are the Primary Causes of Gynecomastia?

In almost all cases, gynecomastia is triggered by an imbalance of sex hormones. When there is a drop in the male hormone testosterone amid a greater level of the female hormone estrogen, male breasts can develop. There are a few reasons why this imbalance may exist in the man’s body.

Natural Hormone Fluctuations

Men and women have both types of sex hormones in their bodies to some degree. Testosterone and estrogen are responsible for the person developing male or female traits during puberty. Male boys experience a surge of testosterone during this period, leading to a deepening of the voice, growth of hair in new places, and an increase in muscle mass. Women go through changes also, including the growth of breasts.
Men also produce estrogen and women produce testosterone. In both sexes, the alternating hormone is in a lesser quantity. In boys and men with too little testosterone and too much estrogen, male breast growth is the inevitable result. This imbalance can affect any male at any age.

It might surprise you to learn that half of all male infants are born with enlarged breasts. Experts think this is caused by the mother’s estrogen levels. In most of these cases, the swollen breast tissue shrinks on its own and disappears completely within two or three weeks after birth.

Male Boys at Puberty

All teenagers go through hormonal changes. For gynecomastia in teens, the hormone changes produced a surge of estrogen, which led to the swelling of their breast tissue.

For many puberty-aged boys with gynecomastia, the swollen breast tissue will go away within six months to two years. That’s without treatment. Boys with persisting breast tissue may be recommended for male gyno surgery.


A man will experience declining levels of testosterone the older he gets. By age 50 and all the way to 69, the declining testosterone can lead to male breast growth. It’s said that one in four men in this age category are affected by adult gyno.

Medications that Can Cause Gyno

The imbalance of hormones could be caused by a medication the man is taking. The most common medications that lead to the growth of breasts include:


These are drugs used to treat ailments like prostate cancer and enlargement of the prostate. Anti-androgens go by many names including Propecia, Proscar, Flutamide, and Carospir.

Anabolic Steroids

Athletes and bodybuilders are known for using and abusing anabolic steroids. Whether illegally used or prescribed, the drugs, which include androgens, can lead to the male bodybuilders developing gynecomastia symptoms.

AIDS Medication

Gynecomastia can develop in HIV-positive men who are receiving a regimen of antiretroviral drugs. The most common HIV medication that is commonly associated with male breast growth is called Efavirenz or the brand name Sustiva.

Other Medications

Other drugs can cause swelling of male breasts including ulcer medications, stomach-emptying medications, cancer treatments, antibiotics, and tricyclic antidepressants. Valium or diazepam, which are prescribed for anxiety, may also lead to gyno symptoms.

Other Factors Causing Gyno

Illegal Drugs and Alcohol

We mentioned illegal steroids, but a few other non-prescribed substances can lead to male breast growth as well, including marijuana, heroin, methadone, amphetamines, and alcohol.

Health Issues

Male breast growth and breast tenderness can sometimes be caused by certain illnesses that affect the balance of hormones.


While not necessarily an illness, aging can cause hormone changes, especially in men who are overweight or obese.

This is a condition that affects the male’s normal testosterone production. Hypogonadism can be caused by a pituitary insufficiency or a disease called Klinefelter syndrome, which is a genetic condition in which the male is born with an extra X chromosome.


When the thyroid produces too much of the hormone thyroxine, hyperthyroidism results, which can then lead to gynecomastia symptoms.

Liver Failure

When the liver fails, most often due to cirrhosis, it can lead to a hormone imbalance in the body. Some cirrhosis medications are also associated with male breast growth.


Some tumors, including those found on the testes, pituitary gland, and adrenal glands, can produce hormones that alter the balance between testosterone and estrogen.


Not eating enough of the right nutrients and starvation can cause testosterone levels of plummet while estrogen levels typically remain the same. Gynecomastia can result even if the male goes on to resume normal nutrition.

What are the Symptoms of Gynecomastia?

A boy or man who experiences male breast growth may experience breast tenderness on one or both sides of the chest. In almost all cases, there will be subtle or considerable swelling of the breast tissue. In pronounced cases, the condition can give the man female-centric breasts (nicknamed “man boobs”).

These symptoms can make it difficult to wear certain clothing. The man may decide to wear shirts while swimming or while lounging on the beach. Going bare-chested, by comparison, may make the male feel embarrassed. Gynecomastia treatment can help to restore the chest to a masculine shape, uplifting the man’s confidence.

These symptoms are aesthetic in nature and don’t warrant an immediate visit to a surgeon’s office. You should see a doctor immediately if the swelling around the male breast is accompanied by pain or discharge of the nipple. These can be symptoms of more serious conditions, like cancer.

How is Gynecomastia Diagnosed?

A diagnosis for gynecomastia can only come about after a sit-down session with an experienced medical professional.

Ideally, you will visit a gynecomastia surgeon, who can provide an accurate diagnosis following a physical exam and review of your medical history. The surgeon will perform a breast exam to rule out breast cancer and to potentially diagnose the type of gyno present. The breast exam involves the search for a firm, rubbery disk of tissue.

This mass is usually located directly beneath the nipple. The doctor will know that gynecomastia is the cause of male breast growth when the lump under the areola is easily moveable.

During the test, the surgeon may come across a condition that sometimes mimics the effects of gyno. Fatty breast tissue, for example, is the name for breast fat that resembles gynecomastia. Breast cancer is uncommon in men, but it can occur.

When enlargement of the breast is paired with a firm nodule under the skin, the doctor may order a biopsy to rule out a breast tumor. A breast abscess can also look like gyno and is actually an infection of the breast tissue.

During the consultation, the surgeon will also review any medications you may be taking, and may ask about supplements and herbal remedies, which can also lead to gynecomastia effects. In some cases, the surgeon will order medical tests to determine if other conditions are the cause of your male breast growth problem.

You may receive a mammogram or breast ultrasound to rule out breast cancer, while blood draws can check for other conditions, including a hormone imbalance.

How is Gynecomastia Treated?

Gynecomastia treatment can vary depending on the cause of the gynecomastia and the sufferer’s age. Puberty age boys may be told to wait to determine if the gynecomastia will subside on its own. Even some men may be told to stop taking medication or to alter their lifestyles somewhat to see if the male breast growth shrinks without treatment.

When surgery is recommended, male breast reduction and liposuction are the most common procedures used to correct gynecomastia.

Male Breast Reduction

Male breast reduction is the most effective treatment for the correction of gynecomastia. This surgery, which is cosmetic in nature, is designed to remove excess fat and glandular tissue that may exist under the skin. By the end of surgery, the patient will have a flatter, firmer chest with a more masculine shape.


Male breast growth can be caused by a combination of glandular tissue and excess fat. Male breast reduction is useful for cutting away any glandular tissue that exists under the nipple. For the excess fat, the surgical technique most commonly used is liposuction. Lipo can be used alone or in conjunction with male breast reduction, depending on the severity of the condition.

Treating gynecomastia with liposuction can involve a local anesthetic or general, depending on the surgeon’s preference. A small incision is made on either side of the chest, then a thin tube called a cannula will be inserted into those cuts to suction away the fat. The incisions are tiny and usually located on either side of the chest.

Some surgeons choose to place the cuts on the edges of the areola or within the armpit so the scars will be hidden when healed. By suctioning away the excess fat, the surgeon is able to sculpt the contours into a more masculine albeit natural shape.

Male Breast Reduction with Tissue Excision

When the gynecomastia symptoms are severe, surgical tissue excision may be used to achieve the most aesthetically pleasing results. This procedure is reserved for patients with saggy or stretched skin around the breasts.

During the procedure, the surgeon will remove a greater amount of glandular tissue and skin than was possible with liposuction alone.

The tissue excision procedure is performed as an outpatient procedure. The surgeon will use general anesthesia but may also use a local along with sedation.

What is Recovery Like After Gynecomastia Treatment?

The recovery process is similar for both liposuction and male breast reduction with tissue excision. You will experience some soreness and swelling near the treatment area for a couple of weeks. You may be asked to wear a compression garment for a week or more.

This constricting vest helps to reduce swelling and improve circulation, which in turn helps with healing. You can typically return to work within one week of surgery. As for the weight room and other forms of strenuous exercise, you can usually go back to the gym within a couple of weeks.

What Do the Results of Gynecomastia Surgery Look Like?

You should notice immediate improvement in the shape and appearance of the chest region following gynecomastia surgery. You may experience some soreness, but most patients report very little pain in the first few days after the procedure. Any discomfort you feel should be minimal.

Report any discomfort you do feel to your gynecomastia doctors, no matter how severe. Your cosmetic surgeon may prescribe pain medication for any pain you experience, though some surgeons tell you Tylenol is sufficient.

The results of the procedure are permanent. With the glandular tissue and excess fat now gone, your chest contours should remain. You can ensure that your results last for many years to come by watching your weight and curbing things like illegal drug and steroid use.
