Gynecomastia—the development of excess male breast tissue—can have a profound effect on a man’s quality of life and mental health. Often linked to hormonal imbalance, obesity, or certain medical conditions, this condition may cause physical discomfort and emotional distress. Dr. Karen Horton, a Board-Certified Plastic Surgeon in San Francisco, offers advanced gynecomastia surgery to help patients achieve a more masculine chest and renewed confidence.
Gynecomastia is the growth of male breast tissue due to hormonal imbalance, medications, or health conditions. It can impact mental health and quality of life. Dr. Karen Horton offers expert gynecomastia surgery in San Francisco to restore chest contour, improve confidence, and address both cosmetic and medical concerns.
Gynecomastia is a medical condition characterized by the proliferation of glandular tissue in the male chest, resulting in visible breast enlargement. Unlike fat accumulation alone, which is termed pseudogynecomastia or lipodystrophy, true gynecomastia involves actual growth of breast tissue. This condition can affect one or both sides of the chest and may be accompanied by nipple discharge, tenderness, or asymmetry. Gynecomastia can occur at any age but is most commonly seen during puberty, in older men, and during periods of significant hormonal changes.1
Distinguishing gynecomastia from pseudogynecomastia is crucial for determining appropriate treatment options. While both conditions may appear similar, only gynecomastia involves glandular tissue proliferation, often requiring a different clinical approach, such as gynecomastia surgery, liposuction, or a combination of both.
Up to 70% of men may be affected by gynecomastia.2 There are many causes of gynecomastia, and they often involve a disruption in the balance between testosterone levels and estrogen levels. Conditions that reduce testosterone or increase estrogen can trigger the development of male breast tissue. Common etiologies include:
In some situations, pediatric and adolescent patients may experience pubertal gynecomastia, which often resolves on its own. However, persistent or severe cases may warrant evaluation by a Plastic Surgeon with expertise in endocrinology and surgical treatment. A detailed physical examination, assessment of hormone levels, and diagnostic imaging or biopsy may be recommended to identify the root cause and rule out serious conditions such as breast cancer.
Undergoing gynecomastia surgery can offer numerous benefits:
Ideal candidates for gynecomastia surgery include:
Male breast enlargement typically includes a combination of excess glandular tissue and fat, and in some cases, stretched or sagging skin. Treatment is tailored to the underlying causes and the individual’s anatomy. Most procedures are performed on an outpatient basis and may take one to several hours, depending on the complexity of the case.
When dense glandular tissue is present, Dr. Horton may recommend surgical excision through a discreet incision along the lower edge of the areola. This approach allows for precise removal of firm breast tissue and any associated fat deposits. In some cases, excision is combined with liposuction to further contour the chest.
For patients whose breast fullness is primarily due to fatty tissue, liposuction may be the preferred method. Dr. Horton often uses advanced techniques, including ultrasound-assisted liposuction (UAL or VASER), to gently break up and remove fat through small incisions placed near the areola or along the underarm. If dense glandular tissue remains under the nipple, excision may be added to achieve optimal results. You can learn more in Dr. Horton’s dedicated Liposuction section.
In cases of significant gynecomastia with skin laxity or drooping, a more extensive approach may be needed. Extended male breast reduction addresses large volumes of excess tissue and stretched skin, often requiring longer incisions and a more involved recovery. Liposuction may still be used in conjunction with excision, and a surgical drain might be placed temporarily to reduce fluid buildup. This approach is typically reserved for men with severe or longstanding gynecomastia or post-weight loss patients with excess chest skin.
Preparation involves:
Important Note:
Patients taking GLP-1 medications (e.g., semaglutide) for diabetes or weight loss should stop these drugs at least one week before surgery under general anesthesia to minimize the risk of aspiration due to delayed gastric emptying. Consult with your healthcare provider for personalized guidance.
Incisions from gynecomastia correction are closed with dissolving sutures (stitches) and are usually covered with a soft dressing. The chest is wrapped with a compressive garment to encourage skin contraction to its new contour.
You may experience some mild discomfort over the first week, for which you are prescribed oral pain medication. Mild swelling of the chest area and bruising will resolve within two to three weeks.
You’ll return to the office a few days after surgery for your initial dressing change. If surgical drains were placed, they are typically removed at this visit. Dr. Horton will advise you to continue wearing your compression garment for several weeks to support the healing process and help shape your chest. Postoperative garments are generally provided after surgery, so there’s no need to purchase anything additional unless specifically directed.
You may shower after your first dressing change, and you can return to work when you feel ready, often within a day or two after surgery. You should avoid sexual activity for a week or two, and heavy exercise for about three to four weeks. Try to avoid participating in sports or activities that risk a blow to the chest area for a few weeks after surgery. Any discomfort you may experience will begin to fade as you heal over the first month.
Wearing your compression garment consistently under your clothing can help reduce swelling (edema) and support the healing process. Final results develop gradually—while many improvements appear within a few months, it may take up to a year for the full outcome to be visible. Give your body the time it needs to recover fully and naturally.
To protect your incisions during the healing process, it’s important to avoid direct sun exposure on your incisions for at least six months to a year. UV rays can darken healing scars, leading to long-lasting discoloration known as hyperpigmentation. While avoiding the sun isn’t possible every day, it’s important to apply a broad-spectrum sunscreen with at least SPF 30 to your scars—even if your incisions are covered by light clothing. Please see Dr. Horton’s Scar Therapy section for more guidance on postoperative management of scars.
At your initial consultation, Dr. Horton will spend a great deal of time getting to know you personally and taking a complete medical history. As a Plastic Surgeon who performs a great deal of breast surgery, she intimately understands how a man’s body image is often related to his chest contour. Dr. Horton aims to help you achieve the result you are looking for! She will explore your reasons for seeking gynecomastia correction, examine your chest, and if you are an appropriate candidate for surgery, your options will be described in detail.
