Gynecomastia, the enlargement of breast tissue in men, is far more common than most men realise, yet it can be a source of real self-consciousness: avoiding fitted shirts, hunching the shoulders, or never taking off a T-shirt on the beach or in the gym. At her practice on Harley Street in London, Ms Anna De Leo offers gynecomastia surgery that removes excess glandular tissue and fat to restore a flatter, more masculine chest contour.
Every man's chest is different. Some have mostly fatty fullness, others a firm disc of glandular tissue behind the nipple, and some have loose skin after weight loss. Ms De Leo begins with a careful assessment of the cause and composition of your enlargement, then designs a male breast reduction that addresses it precisely, with incisions placed to be as discreet as possible. Discretion, respect and straightforward advice are central to every consultation.
01What Is Gynecomastia?
Gynecomastia (also spelt gynaecomastia) describes a benign enlargement of the male breast gland. It is distinct from pseudogynecomastia, where the fullness is caused by fat alone, although many men have a combination of the two. It can affect one or both sides and is most often noticed in adolescence, in middle age and later life.
Common causes include:
- hormonal imbalance between testosterone and oestrogen, which may occur naturally during puberty or with age;
- weight gain, as fatty tissue converts more testosterone to oestrogen;
- anabolic steroids, performance-enhancing substances and some recreational drugs, including cannabis;
- certain prescribed medicines;
- liver, kidney or thyroid conditions, and, rarely, hormone-producing tumours.
In many cases no single cause is found. Because gynecomastia can occasionally signal an underlying medical issue, part of the assessment is to make sure nothing important has been missed before surgery is considered.
It is worth remembering how common this is. Gynecomastia affects a large proportion of men at some point in their lives, and men of every age and background come to our London practice with exactly the same concern. Seeking advice is a sensible, practical step, not vanity.
02Who Is a Candidate for Male Breast Reduction?
Gynecomastia surgery may be suitable if you:
- have persistent chest enlargement that has not improved with time, weight loss or exercise;
- have firm, rubbery tissue behind the nipple, or puffy, protruding nipples;
- have stopped any medication or substance that may be contributing, where safe to do so, and the enlargement remains;
- are close to a stable, healthy weight;
- are a non-smoker, or prepared to stop before and after surgery;
- have realistic expectations about what surgery can achieve.
Adolescent gynecomastia often settles on its own within two to three years, so teenagers are usually advised to wait. If enlargement has appeared recently, is painful, affects only one side with a hard lump, or is accompanied by nipple discharge or skin changes, it should be assessed by your GP promptly, as these features need investigation first.
03Your Consultation on Harley Street
Your consultation is held privately with Ms Anna De Leo at 64 Harley Street in Marylebone. She will take a detailed history, including when the enlargement began, your weight history, any medicines, supplements or steroid use (discussed in strict confidence and without judgement), and relevant medical conditions. A clinical examination helps distinguish glandular tissue from fat and assess skin quality and chest symmetry. Depending on your history, blood tests or an ultrasound scan may be arranged before surgery.
She will then explain the technique best suited to your chest, where any incisions would be placed, the likely recovery and what result is realistic. You will receive written information, and as with all cosmetic surgery there is a cooling-off period of at least two weeks between consultation and surgery, in line with GMC guidance.
When it comes to gynecomastia cost factors, your personalised plan depends on whether liposuction, gland excision or skin reduction is required, the type of anaesthetic, the length of surgery, hospital fees at a CQC-registered facility in London and the aftercare provided. These are set out clearly in writing.
04Gynecomastia Surgery Techniques
The right operation depends on what the chest is made of. Ms De Leo tailors the approach to your anatomy:
Liposuction
Where fullness is mainly fatty, liposuction through tiny incisions at the edge of the chest can remove fat and contour the surrounding area, including the sides of the chest towards the armpit. The incisions are only a few millimetres long and usually fade well.
Gland excision
True glandular gynecomastia does not respond to liposuction alone, because the gland is dense and fibrous. It is removed through a small incision along the lower border of the areola, where the change in skin colour helps the scar blend. A thin layer of tissue is left beneath the nipple to avoid a sunken appearance.
Combined approach
Most men benefit from a combination of liposuction and gland excision, which gives a smooth, even transition from chest to abdomen and armpit.
Skin reduction
After major weight loss there may be loose skin that will not retract. In these cases additional skin removal, and sometimes repositioning of the nipple, is needed. This leaves longer scars, which Ms De Leo will discuss openly with you.
Many patients can have surgery under local anaesthetic with sedation, while others are better suited to a general anaesthetic; the choice depends on the extent of surgery and your preference.
The aim is not a sculpted chest from a magazine, but one that looks naturally masculine, suits your build and lets you stop thinking about it.

05Gynecomastia Recovery Time
Most men go home on the day of surgery. You can expect the following:
- First few days: swelling, bruising and tightness across the chest, usually well controlled with simple pain relief.
- About one week: return to desk-based work, avoiding heavy lifting.
- 4–6 weeks: wear a compression vest day and night to support the tissues and help the skin settle to its new contour.
- Around six weeks: gym training, contact sports and heavy chest exercises can usually resume gradually after review; before then, sport should be avoided.
- 3–6 months: residual swelling resolves and the final contour becomes clear.
Recovery at ADLSynergy is actively supported. Our team provides scar therapy, lymphatic drainage to help reduce swelling and firmness, and practical advice on posture and breathing as the chest heals. Optional therapies, including oxygen therapy and nutrition and health optimisation through our longevity service, can be added to your plan.
06Risks and Realistic Results
Gynecomastia surgery is generally well tolerated, but like any operation it carries risks. These include bleeding or haematoma, a collection of fluid (seroma), infection, visible or thickened scars, contour irregularities, asymmetry between the two sides, and changes in nipple sensation. Removing too much tissue can create a sunken nipple, and removing too little may leave residual fullness; careful technique aims to avoid both. Occasionally a small revision is needed.
The results of surgery are long-lasting when the underlying cause has been addressed. However, significant weight gain, anabolic steroids or certain medicines can cause gynecomastia to return. Gynecomastia before and after images can show what is possible, but they reflect other men's anatomy and healing. Results vary, and the aim is a natural, masculine chest that fits your build, not an exaggerated or over-sculpted look.
