Gynecomastia Surgery
Gynecomastia (pronounced guy-neh-co-mastia) is Greek for "women's breasts". The term was first coined by Galen, a second-century AD physician. Gynecomastia describes excess glandular and/or fatty breast tissues in man.
Gynecomastia is a male breast disorder. Depending on the patient's clinical condition, gynecomastia surgery and gynecomastia corrective surgery may be insurance and Medisave claimable. Enlarged male breasts come in various degrees ranging from very mild to significant enlargement, often accompanied by sagging skin, causing pain and discomfort for men.
Gynecomastia, also known as manboobs, is a benign enlargement of the male breast. It is defined as the presence of abnormal proliferation of breast tissues (glands & fats) in males. Gynecomastia may cause discomfort, pain and severe distress emotionally and physically. This medical condition is the most common male breast deformity, affecting over 65 percent of young and adult men globally.
True Gynecomastia
Defined clinically by the presence of firm mass (glandular tissue) that extends concentrically from the nipples.
Mixed Gynecomastia
When both fat and firm mass (glandular tissue) are the cause.
Pseudogynecomastia
It should be differentiated from gynecomastia, as it is characterised by ONLY fat deposition WITHOUT the involvement of enlarged glandular tissue.

An obvious physical sign that a person may be suffering from gynecomastia is when the male breasts resemble that of a female’s breasts. An oversized nipple-areola complex (puffy nipples) can appear distorted and feminine-looking. When the person wears a form-fitting T-shirt, the breasts look like female breasts. Other symptoms may also include swelling, pain, soreness and, in some extreme cases, nipple discharge.
A self-check method is to gently pinch the nipple with your fingers. If you can feel a tender, firm and mobile disc-like mound of tissue when pressure is applied, you might be suffering from gynecomastia. Gynecomastia can occur unilaterally (one-sided) or bilaterally (both sides). If you have man boobs, take a few moments to answer these questions sincerely and note your emotions as you think about your answers:
• How does removing your shirt in front of others make you feel?
• Does the thought of your others staring at your chest make you cringe, anxious and even angry?
• Do you feel that there is a possibility of being made fun of by your peers for having a female-like chest?
Body dissatisfaction has resulted in a high percentage of males with extremely low self-confidence, anti-social behaviour and poor mental health and wellbeing. As men are more clammed up about their feelings and insecurities, they tend to take matters into their own hands.
An imbalance of hormones triggers gynecomastia. A decrease in the amount of testosterone level compared with estrogen leads to the condition. The decline in testosterone levels can be caused by conditions that block the effects of or reduce testosterone.
It may also be a condition that increases your estrogen level. Several factors can upset the hormone balance, and these include the following:
Natural hormone changes
The hormones testosterone and estrogen not only control the development but it is a maintenance of sex characteristics in both men and women. Testosterone takes control of male traits, such as muscle mass and body hair, while estrogen takes control of female characteristics, including the growth of breasts. Most people associate estrogen as an exclusively female hormone, but the truth is, men also produce it — though generally in small quantities.
However, when male estrogen levels are too high or are out of balance with testosterone levels, this can cause gynecomastia.
Health conditions
Several health conditions can cause gynecomastia by tilting the average balance of hormones. These include:
• Any conditions that interfere with normal testosterone production, such as Klinefelter's syndrome or pituitary insufficiency, can be associated with gynecomastia.
• Hormone changes that occur during the normal course of ageing can cause gynecomastia, especially in overweight men.
• Some tumours, such as those involving the testes, adrenal glands or pituitary glands, can produce hormones that alter the male-female hormone balance. In this condition, the thyroid gland produces too much of the hormone thyroxine.
• Kidney Failure: About half the people treated with regular hemodialysis experience gynecomastia due to hormonal changes.
• Liver Failure And Cirrhosis: Hormonal fluctuations related to liver problems and medications taken for cirrhosis are associated with gynecomastia.
• Malnutrition And Starvation: When your body is deprived of adequate nutrition, testosterone levels drop while estrogen levels remain constant. As such, this causes a hormonal imbalance. Unfortunately, Gynecomastia may persist despite resuming normal nutrition.

Gynecomastia (True and Mixed) is universally classified under Gynecomastia Scale under Grade I, II, III and IV, according to the severity of breast tissue enlargement.
Gynecomastia Grade I
Small breast enlargement with a localised button of tissue that is concentrated around the areola. At this stage, it is generally less noticeable with clothing but can be evident when undressed.
Gynecomastia Grade II
Grade II gynecomastia is most commonly seen; it involves moderate male breast enlargement, which expands up to the width of the chest. Depending on the individual's condition, loose skin may or may not be present clinically.
Gynecomastia Grade III
Grade III will see a moderate to significant enlargement in the breast tissue. This physical change lends an appearance that resembles a woman's breasts and is often noticeable.
Gynecomastia Grade IV
Grade IV gynecomastia is a significant breast enlargement further aggravated with substantial excess skin. This grade is severe and highly visible, giving the appearance of a feminine breast.
Gynecomastia in adolescents
According to statistics collected by the National Institutes of Health (NIH) statistics Singapore, about 50 to 60 percent of adolescent males experience gynecomastia.
Symptoms in adolescent males who suffer from gynecomastia are usually caused by male hormonal changes, resulting from the effect of an altered estrogen/androgen balance on the breast tissues or, it can also result from an increased sensitivity of breast tissue to normal estrogen level.
Although it is not unusual for the condition to regress over time, this is unfortunately not always the case for some.
Gynecomastia in adult men
Gynecomastia is even more common among adult men. Nearly 65 percent of men between 27 and 92 years old had some kind of gynecomastia. Although the symptoms may be similar, the causes of gynecomastia in adolescents and adults are very different. Adult gynecomastia is usually associated with increasing age due to progressive testicular hypofunction and increased weight and body fat.
The prevalence of this condition peaks again between the ages of 50 and 69, with at least 1 in 4 men in this age group being affected.

Glands of enlarged male breasts from a male patient, excised by Dr Ivan Puah, who has been performing gynecomastia surgery for over a decade.
Ideally, the male chest should be flat with the pectoralis muscle accentuated. In the gynecomastia patient, the male breasts possess a more pyramidal shape with feminine features.
The enlarged male breast tissue appears to have a unifying shape of a head, body, and tail. The head is semicircular in shape and is located more medially toward the sternum. Most glandular tissue consists of a body found immediately deep into the nipple-areolar complex. The tail appears to taper off the body more laterally and toward the insertion of the pectoralis major muscle onto the humerus.
Understanding the anatomy of the gynecomastia gland guides a gynecomastia doctor to perform a more thorough and sufficient gland excision.
Pseudogynecomastia is also a real issue. Unlike gynecomastia, it is caused by the presence of excess fat not involving glandular tissue proliferation. Men who suffer from pseudogynecomastia will be advised to make lifestyle changes such as embarking on an exercise and weight loss program.
If no change is observed, surgical fat removal in the form of liposuction will be recommended. Gynecomastia, on the other hand, does not respond to diet, exercise or liposuction alone.
Here's a guide on the efficacy of the different treatments for treating gynecomastia and pseudogynecomastia.
Exercise
It has little effect on those suffering from gynecomastia besides helping to get rid of excess fat. Exercise has no effect on the glandular tissue, which is a concern of gynecomastia patients. For pseudogynecomastia patients, exercise and a healthy diet may help to improve their condition.
Non-invasive Fat Reduction Treatment
The pills or lotions that promise to reduce the size of your gynecomastia that you found online are nothing but a gimmick. Nothing you do, eat or apply can reverse the enlargement of your breast glands; neither can fat freezing or low-energy laser, except for surgical intervention, in the form of gynecomastia surgery.
Liposuction
Liposuction (also known as lipoplasty) is a body contouring and fat removal surgery to correct disproportionate body shape and remove excess stubborn fat resistant to exercise and diet. It is useful in treating pseudogynecomastia. However, in true gynecomastia and mixed gynecomastia cases, the patient will require BOTH liposuction and glandular tissue removal surgery.
Contrary to popular misconception, being overweight is not the only cause of gynecomastia. It may be caused by genetics and ageing as some men experience bodily changes as they grow older.
Gynecomastia is an endocrine system disorder that causes an enlargement in the size of male breast tissue. Other causes of man boobs may be due to:
Certain medications
Some antibiotics, heart medicines, heartburn medications, anti-anxiety drugs, antidepressants, and other medications
Drugs and Alcohol
Medical Conditions
An overactive thyroid, kidney disease, etc
Breast cancer is not only subjected to women as men can get them, although it accounts for only 0.2 percent of all malignancies in male patients.
Gynecomastia, however, is not a sign of developing breast cancer. Also, excessive breast development and breast cancer are not correlated.
According to statistics, male menopause or andropause happens when testosterone production drops in men aged 50 or older. Testosterone fuels changes during puberty and affects a man's mental and physical energy. It also regulates other vital evolutionary features.
As the levels of testosterone drop, it causes a hormonal imbalance, which may eventually lead to the development of gynecomastia.
For those who are overweight, it is assumed that they can lose the extra fat prevalent in the chest area with dieting and exercise, only to worsen the situation, causing the unflattering chest to appear more noticeable. .
Maintaining a healthy weight and body is always recommended. If being overweight is an issue, do try to lose the extra weight. If you think you're suffering from gynecomastia, seek a qualified doctor's advice as soon as possible to safely and effectively address the issue.
Gynecomastia can cause physical discomfort and pain both in adolescence and adulthood. This is more so when the breast enlarges and becomes significant in size, where a slight contact can cause considerable discomfort.
Teenagers may be uncomfortable discussing the issue and therefore may keep it from their parents and family members. This can lead to long-term adverse effects such as low-self esteem, depression, and lack of body confidence.
The following are some helpful ways to detect if your child or may be suffering from gynecomastia:
Physical change
One of the most obvious signs is abnormal breast development. An increase in size and changes in appearance (where the breasts seem identical to a woman's), including enlarged areolas, could indicate gynecomastia. Your child may also slouch more and opt to dress up in baggy tops.
Change in behaviour
The child may seem more withdrawn, prefer to be alone, opting out of social activities, including the family. His mood swing may become more erratic.
Pain
He may complain of discomfort, soreness and pain in the breasts. Although rare, there may be a nipple discharge as well.
The above are just possible indications that your child may be suffering from gynecomastia, but it is not definitive. If it is suspected, striking up a conversation would be a good start, but it has to be done tactfully so that it does not cause (further) embarrassment to the child.
Your child needs to understand that the issue can be resolved, and seeking a doctor's consultation is the best way to assess and establish if it is indeed gynecomastia.
Generally, to diagnose teenage gynecomastia, hormone lab tests are not really needed to establish the presence of gynecomastia.
According to Dr Ivan Puah, Medical Director, Amaris B. Clinic," History taking and physical examinations such as pinch tests are the keys to diagnosing if the patient is suffering from gynecomastia for this group of patients." Dr Puah has treated many gynecomastia patients, successfully performing the procedure for over 15 years.
The pinch and touch test done by Dr Ivan Puah determines if a patient has gynecomastia. The presence of a mound of fibrous and firm tissue is almost always a good indication. Besides that, he will also assess the patient for skin laxity and the presence of excess fat on the chest.
During the consultation, a detailed medical history, patient's experience, and family history will also be taken.
Unfortunately, it is impossible to get rid of gynecomastia with exercise because the majority of the time, the problem is excess glandular tissue that no amount of exercise or healthy eating will eradicate.
In fact, many men have reported that as they lose weight, the gynecomastia looks worse because the fatty tissue around the gland shrinks and the gland subsequently stands out more, making the condition more prominent.
The more fat tissues you carry, the higher your chance of developing gynecomastia, so the problem is prevalent among overweight men. However, men in great shape also suffer from the condition because it is caused primarily by a hormone imbalance.
Gynecomastia is caused by hormone imbalance, so while exercising is good, it does not resolve the underlying issue at all.
Yes, the predominant treatment to deal with gynecomastia is surgical - gynecomastia surgery.
Despite what's being purported, there is no scientific evidence to prove that topical creams, fat freezing machines, fat reduction machines, or massage techniques can solve the condition permanently. Gynecomastia surgery is the option for surgical correction of gynecomastia.
Soy contains isoflavones, a class of phytoestrogens which may mildly mimic the hormone estrogen. The effects of soy isoflavones on estrogen levels are complex, but in general, soy is safe to be consumed in moderation. Eggs, milk and other food products that contain hormones are safe for consumption when taken in moderation.
Hoppy beers like IPA (Indian Pale Ale) contain phytoestrogen, a plant-based estrogen hormone. The common myth is that drinking too much of them will cause estrogen levels to skyrocket. The phytoestrogen levels are too low to create any hormone imbalance. But still, consuming beers or any alcohol excessively can be detrimental to your overall health.
Gynecomastia surgery is recommended for those whose gynecomastia has persisted for more than one year and those whose gynecomastia does not resolve independently or with other means of management.
The objective of gynecomastia surgery is to reconstruct the male chest contour, obtain a histological clarification of the suspicious breasts lesions, and to relieve the symptoms such as pain and discomfort due to the distention from the hypertrophied breasts. Gynecomastia surgery can treat males with bilateral or unilateral gynecomastia, with protruding and prominent areolas.
We believe a detailed clinical consultation and physical examination play an integral part in diagnosing your condition and planning a tailored treatment for you. During the consultation, Dr Ivan Puah will conduct a series of physical assessments and questions while establishing a full report on your concerns.
History and physical examinations are crucial elements when considering gynecomastia diagnosis [1]. Longstanding stable cases in an adult do not require blood tests other than those that would be necessary for gynecomastia surgery. Blood work may include liver function tests and assays for:
• follicle-stimulating hormone,
• Luteinising hormone,
• thyroid-stimulating hormone,
• thyroxine,
• estrogen,
• estradiol, and
• testosterone levels.

Questions that Dr Ivan Puah may ask
• Medical history
• When and how long you've started noticing the signs of abnormal chest enlargement
• Any pain or discomfort accompanying the physical changes?
• Medications that you have taken or are currently taking
• Your diet, lifestyle and activity history
• Any surgery performed, injuries or any other health concerns that he needs to take note of
• Does the condition affect you while you continue your daily activities and life?
Endoscopic-line incisions not bigger than 4mm are made strategically on the target area to allow infiltration of anaesthetic fluid.
Through the small incision, a 360° glandular tissue dissection is performed carefully following the physiological disposition of the glandular tissues. Not only can the affected tissues be removed effectively, but scarring is also minimal, and the risks of haematoma are significantly reduced.
Patients treated with 360°GTD® do not require suction drainage, which typically leaves ugly scars and increases the risks of infection post-op.
For those patients whose gynecomastia also comprises excess chest fat, Dr Ivan Puah will perform modern liposuction with his MDC-Sculpt®️ Lipo Technique. He carefully removes stubborn fat with a specialised cannula, further contouring and sculpting the area for a more defined chest contour.
Each gynecomastia case is unique. The surgical approach developed by Dr Ivan Puah considers the degree of the gynecomastia, glandular tissue-to-fat ratio and parenchyma distribution of the patient. He will propose an individualised approach for the patient after carefully assessing the patient's clinical condition and understanding the patient's concerns.
Dr Ivan Puah's ultimate aim is to remove fibrous and painful glandular tissues and/or fat tissues to restore a natural-looking masculine body shape with the smallest possible incision for his patients.
Depending on the clinical condition of the individual, the gynecomastia surgery may take 1.5 - 2.5 hours. It will be performed in our accredited Day Surgery and the patient will be taken care of by trained surgical and medical personnels. The patient is discharged on the same day for rest. Most patients can resume work within a day or two.
Making the appropriate choice is pivotal when addressing an issue like gynecomastia. As much as we want it to be resolved as quickly as possible, it is advisable not to be too hasty in searching for help. Plenty of horror stories and botched jobs remind us of this importance.
Here are a few tips to note when deciding on your doctor.
Experience
An experienced doctor can not only identify the underlying issues of a condition, but they can also effectively address it safely with satisfying results. Look for a doctor that does the procedure regularly (with proven results) and one who is meticulous and particular about standards and quality.
Before & After Patient Photos
The doctor should be able to show you various grades of gynecomastia cases that they have performed, in the form of "before" and "after" photos. Most often, these are good indicators of the quality, standard and results you can expect.
Communication Skills
• It is essential that a doctor makes you feel comfortable and can answer your concerns and queries.• The doctor should also be able to explain the reason/s a particular procedure is chosen or preferred over another to address your issue.
• A doctor should be patient when addressing questions and concerns. He should not overwhelm or pressure a patient into agreeing to treatments that they (the patients) do not understand regarding the purpose of such treatments.
• A doctor should be able to convey his opinions in a manner that is easily understood and assure his patients, particularly in regards to their safety during the procedure.
Additionally, the clinic staff should also be exemplary of the quality and care standard of the clinic. They ideally should have decent experience and knowledge in dealing with patients with different issues and needs.
Your experience from the moment you step into the clinic until you leave should cast a positive imprint and make you feel confident.
No. As gynecomastia surgery involves liposuction and breast tissue removal, all doctors offering this service, including plastic surgeons alike, must meet the stringent criteria set by the board and be liposuction accredited by the Ministry Of Health Singapore. Dr Ivan Puah is one of the doctors to receive the accreditation.
Yes, full male body contouring is sought after by male patients, and they usually request for fat reduction of the face, abdomen and waists at the same time as their male breast reduction surgery.

Dr Ivan Puah is an accredited liposuction doctor in Singapore with over 17 years of body sculpting experience. He has completed fundamental and advanced body sculpting surgical training conducted by Dr John Millard and Dr Alfredo Hoyos. These two plastic surgeons were the ones who developed VASER (the acronym for Vibration Amplification of Sound Energy at Resonance) liposuction, a liposuction technique with the assistance of ultrasound waves, to break up and liquefy fat cells, making them for easier extraction.
Dr Ivan Puah is certified to perform *VASER liposuction, having completed his liposuction training in the United States and Argentina. He is the Chairman of the Lipo Peer Review Committee in Singapore and has received dedicated surgical training in gynecomastia surgery in the United States of America.
Dr Ivan Puah has developed two proprietary surgical approaches: the 360° Glandular Tissue Dissection (360°GTD®) technique for gynecomastia surgery and the MDC-Sculpt® Lipo technique for liposuction.
Most patients return to work within 2 to 3 days. A compression vest will be prescribed, and the patient will need to diligently use it for at least 6 to 8 weeks, as it will help to reduce the post-tissue swelling and hasten the recovery process. Soreness, discomfort and bruises (if any) are expected and will gradually improve over 1 to 2 weeks.
There is minimal disruption to daily activities. However, please avoid water activities and heavy gym workouts, especially exercises involving the chest and upper body). Dr Ivan Puah will advise you accordingly on the resumption of such activities.
Costs for gynecomastia surgery in Singapore will vary between practices, and the following factors will determine the costs. In general, the doctor’s fee is based on their experience and the complexity of the case.
Other charges will include the type of anaesthesia used, hospital or surgical facility costs, medical tests such as blood tests, scans, post-surgical compression vests, pre and post-medication, histology (biopsy), etc.
While costs are one of the variables you need to consider, the doctor’s experience, the variety of gynecomastia cases he has treated, and your comfort level with the doctor and his team are just as necessary as the final costs of the surgery. Ensure that the doctor you choose performs the procedure in an accredited surgical facility with a team of anaesthetists and, well-trained surgical and medical support staff.
Dr Ivan Puah tailors the approach for the surgery to your clinical condition, considering the gland size, fat layers and skin laxity. He also performs corrective surgeries on patients with botched jobs or unsatisfactory results from other local or overseas practices.
At Amaris B. Clinic, aftercare significantly assists you with faster recovery and ensures optimum results. We have curated a bespoke aftercare program designed to help you with the healing process, such as manual lymphatic drainage massages, skin firming and many others.
Although rare, 10 percent of patients who have had surgery may experience a recurrence of gynecomastia. Ageing, hormonal changes, alcohol, opioids, and certain medications and drugs are usually associated with the onset of gynecomastia.
According to the patients' statistics collected over the years from cases performed by Dr Ivan Puah, gynecomastia surgery yields a high success rate. To minimise the risks of post-surgical complications and achieve the optimal post-surgery results, the patient is advised to follow closely and adhere to the pre-operative instructions and post-treatment care program as planned by Dr Ivan Puah and his medical team.
To know if your condition is claimable by insurance or Medisave, you must first ascertain that your enlarged male breast is a medical condition and is medically necessary to have it removed. We encourage you to consult with Dr. Ivan Puah, who will be able to identify the root cause of your condition. During the consultation, please share with the doctor your complete medical history. A detailed physical examination and appropriate diagnostic tests will also be carried out for a thorough assessment.
Wanting to proceed with Gynecomastia Surgery is personal. It is a practical, permanent, and clinically proven solution to remove fat and excess gland.
