MS. SONAM SHARMA
ASST. PROFESSOR
DEFINITION
Gynaecomastiais the benign enlargement of
breast tissue in males. This condition can affect
one or both breasts, sometimes unevenly. While
it is generally not a serious health issue, it can
cause emotional and psychological distress due
to the altered appearance.
Physiological Causes
Neonatal Gynaecomastia
Cause: Transient increase in estrogen levels from maternal sources.
Mechanism: Maternal estrogens cross the placenta and stimulate breast
tissue growth in newborn males.
Resolution: Typically resolves within a few weeks after birth.
Pubertal Gynaecomastia
Cause: Hormonal changes during adolescence.
Mechanism: During puberty, there is a temporary imbalance between
estrogen and testosterone as the hypothalamic-pituitary-gonadalaxis
matures.
Resolution: Usually self-limited, resolving within six months to two
years.
Senescent Gynaecomastia
Cause: Aging-related hormonal changes.
Mechanism: Decrease in testosterone production
and increased conversion of androgens to estrogens
in peripheral tissues.
Resolution: May persist but often stabilizes;
treatment is considered if symptomatic.
Pathological Causes
Hypogonadism
Primary: Testicular failure (e.g., Klinefeltersyndrome,
orchitis).
Secondary: Pituitary or hypothalamic dysfunction (e.g.,
pituitary tumors, Kallmannsyndrome).
Mechanism: Reduced testosterone production leads to a
relative increase in estrogen activity.
Hyperthyroidism
Cause: Excess thyroid hormone production.
Mechanism: Increased levels of sex hormone-binding
globulin (SHBG) enhance estrogen action.
Chronic Diseases
Liver Cirrhosis: Impaired liver function affects hormone
metabolism, increasing estrogen levels.
Chronic Kidney Disease: Altered metabolism and excretion of
hormones can lead to hormonal imbalances.
Tumors
Testicular Tumors: Secrete estrogens or human chorionic
gonadotropin(hCG), which stimulates estrogen production.
Adrenal Tumors: Can produce estrogens or precursors that are
converted to estrogens.
Pituitary Tumors: Can secrete prolactinor other hormones
that affect the hypothalamic-pituitary-gonadalaxis.
Pharmacological Causes
Medications
Anti-androgens: Used in prostate cancer treatment (e.g., flutamide,
bicalutamide).
Anabolic Steroids: Abuse or therapeutic use can disrupt normal
hormone balance.
Anti-ulcer Medications: Cimetidinehas anti-androgenic effects.
Cardiovascular Drugs: Spironolactone(a diuretic with anti-
androgenic properties), digitalis, and calcium channel blockers.
Antibiotics: Some (like ketoconazole) can inhibit androgen synthesis.
Psychoactive Drugs: Diazepam, tricyclicantidepressants, and some
antipsychotics.
Substance Use
Alcohol
Mechanism: Chronic use can impair liver function,
leading to altered hormone metabolism and increased
estrogen levels.
Illicit Drugs
Marijuana: Active compounds may interfere with the
endocrine system.
Heroin: Associated with changes in the hypothalamic-
pituitary-gonadalaxis.
Amphetamines: Can alter hormonal balance.
RISK FACTOR
Physiological Risk Factors
Age:
Neonatal Period: Newborns may experience
temporary gynaecomastiadue to the influence of
maternal estrogen.
Puberty: Hormonal changes during puberty can lead
to temporary gynaecomastiain adolescent boys.
Aging: Older men are at risk due to declining
testosterone levels and relative increase in estrogen.
Pathological Risk Factors
Hormonal Imbalances:
Hypogonadism: Conditions like Klinefeltersyndrome or
pituitary insufficiency reduce testosterone production.
Hyperthyroidism: Increased thyroid hormone levels can
lead to elevated estrogen activity.
Chronic Diseases:
Liver Disease: Conditions like cirrhosis affect hormone
metabolism, increasing estrogen levels.
Kidney Disease: Chronic kidney disease can alter hormone
levels and contribute to gynaecomastia.
Tumors:
Testicular Tumors: Can produce estrogen or hCG, leading
to gynaecomastia.
Adrenal Tumors: May secrete hormones affecting estrogen
levels.
Pituitary Tumors: Can influence overall hormone balance.
Genetic Conditions:
KlinefelterSyndrome: A genetic condition where males
have an extra X chromosome, often leading to lower
testosterone levels and higher estrogen levels.
Pharmacological Risk Factors
Medications:
Anti-androgens: Used for prostate cancer treatment (e.g., flutamide,
bicalutamide).
Anabolic Steroids: Used for muscle building can be converted to estrogen in
the body.
Antibiotics: Such as ketoconazole, which can affect hormone levels.
Anti-ulcer Drugs: Like cimetidine, which can have estrogen-like effects.
Cardiovascular Drugs: Such as spironolactoneand digoxin, which can
interfere with hormone balance.
Psychoactive Drugs: Including diazepam and tricyclicantidepressants.
Chemotherapy Agents: Certain cancer treatments can disrupt hormone
levels.
Lifestyle and Environmental Risk
Factors
Substance Use:
Alcohol: Chronic alcohol consumption can impair liver function and hormone metabolism.
Illicit Drugs: Use of marijuana, heroin, or amphetamines can contribute to gynaecomastia.
Obesity:
Excess adipose tissue can lead to increased aromataseactivity, which converts androgens
to estrogens, contributing to the development of gynaecomastia.
Herbal Products:
Phytoestrogens: Found in some plant-based products and supplements can mimic
estrogen in the body.
Tea Tree Oil and Lavender Oil: These have been linked to gynaecomastiain case reports
due to their weak estrogenic and anti-androgenic activity.
PATHOPHYSIOLOGY
Aromatase Activity: Some testosterone is converted into estradiol
(a form of estrogen) by the enzyme aromatase.
Testes: LH and FSH act on the testes to produce testosterone.
Pituitary Gland: GnRH stimulates the pituitary gland to secrete
luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Hypothalamus: Releases Gonadotropin-releasing hormone
(GnRH).
Gynaecomastia: The result is the enlargement of male breast
tissue.
Increased Estrogen Activity: This stimulates breast tissue
proliferation.
Estrogen/Testosterone Imbalance: Increased estradiolor
decreased testosterone can lead to a relative increase in estrogen
activity.
SYMPTOMS
Breast Enlargement:
Noticeable increase in the size of one or both breasts.
May occur unevenly, affecting one breast more than the other.
Tenderness or Sensitivity:
Discomfort or pain in the breast area.
Sensitivity to touch, pressure, or movement.
Palpable Lump:
Firm, mobile, rubbery mass located beneath the nipple area.
The lump is usually symmetrical in nature and can be felt with gentle pressure.
Nipple Discharge(rare):
Clear or milky discharge from the nipple.
This symptom is uncommon and warrants further evaluation to rule out other
conditions.
Emotional and Psychological Impact:
Embarrassment or self-consciousness due to breast
enlargement.
Anxiety, depression, or social withdrawal because of
altered body image.
Swelling:
General swelling in the breast tissue.
Sometimes accompanied by a feeling of fullness or
heaviness.
DIAGNOSIS
Medical History
Gathering a thorough medical history is the first step in diagnosing gynaecomastia. This
includes:
Age of Onset: Helps differentiate between physiological and pathological causes.
Duration of Symptoms: Acute or chronic nature of breast enlargement.
Associated Symptoms: Pain, tenderness, or nipple discharge.
Medications: Use of drugs known to cause gynaecomastia, such as anti-androgens,
anabolic steroids, anti-ulcer drugs, cardiovascular medications, and psychoactive
drugs.
Substance Use: Alcohol, marijuana, and other illicit drugs.
Medical Conditions: History of liver disease, kidney disease, thyroid disorders, or
tumors.
Family History: Genetic conditions or history of breast cancer.
Physical Examination
A thorough physical examination includes:
Breast Examination:
Assess for the presence of a firm, rubbery, and mobile mass under the nipple.
Distinguish between true glandular enlargement and pseudogynaecomastia
(fat deposition without glandular proliferation).
Check for asymmetry and unilateral or bilateral involvement.
Abdominal Examination: To detect hepatomegaly(enlarged liver)
or other masses.
Testicular Examination: To identify abnormalities such as small
testes or masses that may suggest hypogonadismor testicular tumors.
Thyroid Examination: To check for signs of thyroid disease.
Laboratory Tests
Laboratory tests are essential to evaluate hormonal levels and organ
function:
Hormonal Profile:
Testosterone: Low levels may indicate hypogonadism.
Estradiol: Elevated levels can cause breast tissue proliferation.
Luteinizing Hormone (LH)and Follicle-Stimulating Hormone (FSH): To
assess testicular function.
Prolactin: Elevated levels can indicate pituitary disorders.
Liver Function Tests: To detect liver disease, which can alter
hormone metabolism.
Renal Function Tests: To check for kidney disease.
Thyroid Function Tests: To assess for hyperthyroidism.
Imaging Studies
Imaging studies are used to evaluate breast tissue and rule out
malignancy:
Ultrasound:
First-line imaging modality to differentiate between glandular and fatty
tissue.
Can detect masses or other abnormalities in the breast.
Mammography:
Considered if there is a suspicious mass or risk factors for breast cancer.
Testicular Ultrasound:
Performed if there are abnormalities on physical examination or
hormonal tests suggest a testicular tumor.
Biopsy
A biopsy is rarely needed but may be performed
if:
There is a suspicious mass.
There are atypical findings on imaging.
There is concern for breast cancer, especially in
patients with risk factors.
TREATMENT
Addressing Underlying Causes:
Hypogonadism: Testosterone replacement
therapy.
Hyperthyroidism: Treatment with antithyroid
medications or other appropriate therapies.
Liver or Kidney Disease: Managing the
primary condition to improve hormone
metabolism.
Medication Review:
Discontinuation or substitution of medications
known to cause gynaecomastia, such as certain
anti-androgens, antipsychotics, or
cardiovascular drugs.
Pharmacological Therapy:
Selective Estrogen Receptor Modulators (SERMs):
Medications like tamoxifenor raloxifenecan reduce
breast tissue size and are used in painful or severe cases.
AromataseInhibitors: Anastrozoleand letrozole,
which reduce estrogen production, can be considered
but are less commonly used due to potential side effects.
Testosterone Therapy: In cases of hypogonadism,
testosterone replacement can help balance hormone
levels.
Surgical Treatment
Indications for Surgery:
Persistent gynaecomastiathat does not resolve with medical treatment.
Severe gynaecomastiacausing significant pain, discomfort, or psychological
distress.
Gynaecomastiawith suspected malignancy (though very rare).
Surgical Procedures:
Liposuction: Effective for removing excess fatty tissue. It is less invasive and
has a shorter recovery time.
Mastectomy: Subcutaneous mastectomy (removal of glandular tissue) is more
invasive but effective for removing dense glandular tissue. This can be done
through a small incision around the areola.
Combination Procedures: Some cases may require both liposuction and
excision to achieve the best aesthetic result.
Lifestyle and Supportive Measures
Weight Loss: Reducing overall body fat can
decrease the appearance of gynaecomastia,
particularly if it is associated with obesity.
Counseling and Support Groups:
Psychological support to address body image
issues and emotional distress associated with
gynaecomastia.
NURSING MANAGEMENT
Nursing diagnosis:
Body image disturbance related to alteration in
physical appearance due to enlarged breast tissue,
as evidenced by verbalization of feelings of

continuity of care and communication among healthcare providers.
COMPLICATION
Physical Complications
Pain and Tenderness:
Gynaecomastiacan cause discomfort and sensitivity in the breast tissue,
which may interfere with physical activities or lead to chronic pain in some
cases.
Infection and Hematoma:
Post-surgical complications, such as infections or hematomas (collection of
blood outside of blood vessels), can occur following procedures like
liposuction or mastectomy.
Scarring:
Surgical interventions can result in visible scars, which might be
aesthetically displeasing or restrict movement if extensive.
Recurrence:
Gynaecomastiacan recur if the underlying cause is not adequately
addressed, necessitating further treatment.
Asymmetry:
Even after treatment, there might be residual asymmetry between the
two breasts, especially if one side was more significantly affected
than the other.
Nipple and Areola Deformities:
Surgical treatments can occasionally lead to changes in the size,
shape, or position of the nipple and areola, which might require
corrective surgery.
Psychological and Emotional Complications
Body Image Issues:
Men with gynaecomastiaoften experience dissatisfaction with their body
image, leading to low self-esteem and poor self-confidence.
Social Anxiety:
The visible nature of gynaecomastiacan lead to embarrassment and
social anxiety, especially in situations involving shirtlessness, such as
swimming or sports.
Depression and Emotional Distress:
The emotional burden of living with gynaecomastiacan contribute to or
exacerbate conditions like depression and overall emotional distress.
PREVENTION
Lifestyle Modifications
Maintain a Healthy Weight:
Obesity can alter hormone levels, increasing estrogen and reducing
testosterone. Regular exercise and a balanced diet can help maintain a
healthy weight and hormonal balance.
Avoid Alcohol and Recreational Drugs:
Chronic alcohol consumption and the use of drugs like marijuana,
heroin, and amphetamines can contribute to the development of
gynaecomastia. Limiting or avoiding these substances can help.
Balanced Diet:
Ensure your diet includes sufficient nutrients that support overall
hormonal health, such as healthy fats, proteins, and vitamins.
Medication Management
Review Medications:
Certain medications are known to cause gynaecomastia. These
include anti-androgens, anabolic steroids, some antibiotics,
anti-ulcer medications, cardiovascular drugs, and psychoactive
drugs. If you are on any of these medications, consult your
healthcare provider about potential alternatives or monitoring
strategies.
Avoid Anabolic Steroids:
Avoid the use of anabolic steroids for bodybuilding or athletic
enhancement, as they can significantly alter hormone levels.
Medical Management
Regular Health Check-ups:
Routine check-ups can help identify and manage conditions that
might lead to hormonal imbalances, such as hypogonadism,
hyperthyroidism, or liver disease.
Early Intervention:
Early treatment of underlying medical conditions like
hyperthyroidism, liver disease, or testicular tumors can prevent the
development of gynaecomastia.
Hormonal Therapy:
For those at risk of developing gynaecomastiadue to hormonal
imbalances, doctors may recommend hormonal therapy or
medications to maintain a balanced hormone level.
Awareness and Education
Understand Pubertal Changes:
Educating adolescents and their parents about the
temporary nature of pubertal gynaecomastiacan
help reduce anxiety and unnecessary interventions.
Informed Decisions:
Awareness about the side effects of certain
medications and substances can lead to more
informed decisions regarding their use.
Monitoring and Support
Regular Monitoring:
If you are on medication that can cause gynaecomastiaor
have an underlying condition that affects hormones,
regular monitoring of hormone levels and breast tissue
can help detect changes early.
Support Networks:
Psychological support for individuals experiencing
gynaecomastiacan help manage emotional distress and
improve overall well-being.
