Gynecomastia is a condition in which a man’s chest develops a shape resembling that of a woman’s breast. It is typically caused by the development of mammary gland tissue beneath the areola.

There are two types of gynecomastia:

  • True Gynecomastia: Enlargement due to developed glandular tissue.

  • Pseudogynecomastia: Enlargement caused primarily by fat accumulation.

This guide will help you identify true gynecomastia through simple self-examination.

Ginecomastia significa letteralmente che i seni di un uomo hanno la stessa forma di una donna.

Il petto maschile ha un aspetto relativamente piatto con pelle, grassi e muscoli.

Step 1: Understand the Normal Male Chest Structure

A typical male chest consists of:

  • Skin

  • Subcutaneous fat

  • Muscle tissue (mainly the pectoralis major)

  • Small traces of mammary gland (normally <1 inch, ~5 grams)

In most men, glandular tissue is minimal and not easily palpable with fingers.

D’altra parte, i seni delle donne hanno un aspetto paffuto a causa del tessuto ghiandolare che si è sviluppato in quella zona.

È possibile verificare se c’è un tessuto ghiandolare mammario strettamente tenuto sotto l’areola.

Of course, normal men also have traces of mammary glands.

However, since they are usually less than 1 inch in size and weigh around 5~10 grams,

they are difficult to hold with your fingers.

Step 2: Check Under the Areola

Using your fingers, gently press around and under your nipple (areola) area.

  • If you feel a firm, rubbery disc or lump beneath the areola, this may indicate developed glandular tissue.

  • If this tissue is easily graspable and surrounded by softer fat, true gynecomastia is likely.

Tuttavia, se la ghiandola mammaria è abbastanza grande da essere palpabile,

e il grasso più morbido si accumula intorno ad esso,

La vera ginecomastia può essere fortemente sospettata.

L’ecografia o la mammografia possono essere utilizzate per una diagnosi accurata,

Ma uno specialista esperto di ginecomastia può facilmente diagnosticare la ginecomastia toccandola leggermente.

E, è necessario ottenere una consulenza dettagliata da uno specialista su come trattarlo.

Step 3: Confirm with a Specialist

Although self-diagnosis is a helpful first step, an accurate diagnosis should be made by a medical professional using:

  • Physical examination

  • Ultrasound or mammography (if needed)

At Evita Clinic, our gynecomastia specialists can usually confirm the diagnosis with a brief touch and visual assessment.

Next Step: Consultation & Treatment Plan

If you suspect you have gynecomastia, schedule a consultation.
We’ll explain your condition in detail and recommend personalized treatment options — surgical or non-surgical.

Most true gynecomastia cases require surgical removal of the gland for a permanent solution.
