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.

男性の胸は、皮膚、脂肪、筋肉のある比較的平らな外観をしています。

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.

一方、女性の胸は、その領域に発達した腺組織のためにふっくらとした外観をしています。

乳輪の下にしっかりと保持された乳腺組織があるかどうかを確認できます。

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.

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.
