Gynecomastia isn't one condition. It's four. Two men can both say they have "gyno" and be describing very different situations: one may notice slight puffiness under a fitted shirt, while the other may have a chest that sags, with the nipple pointing downward.
That difference is described by grades. The grade helps define the surgical technique, and the higher the grade, the more excess skin and nipple position become part of the plan. This article walks through the four grades, how men usually describe each one, and what treatment typically involves.
The medical classification most often cited for gynecomastia is Simon's classification, published in 1973. It uses three grades, with grade 2 split into 2A and 2B. Many clinics communicate the same idea on a 1-to-4 scale, which is the version most men find when they search online and the one AgeFocus uses.
| AgeFocus grade | Simon equivalent |
|---|---|
| Grade 1 · Mild | I |
| Grade 2 · Moderate | IIa |
| Grade 3 · Marked | IIb |
| Grade 4 · Severe | III |
How men describe it: "Puffy nipples." The area shows through a fitted shirt, even in men who are lean and train regularly.
What is usually present: A small disc of gland behind the areola, with no excess skin.
Typical approach: Removal of the gland, sometimes combined with liposuction.
How men describe it: "My whole chest looks soft." Many men at this stage start avoiding light-colored shirts.
What is usually present: Gland spread across the chest, with the contour of the pectoral muscle lost.
Typical approach: Liposuction combined with gland removal.
Grade 2 is reported as the most frequent grade among patients who seek treatment.
How men describe it: "It looks like a breast." At this point, many men avoid the beach and even the gym.
What is usually present: Larger volume and some excess skin.
Typical approach: Liposuction and gland removal, which may also require an adjustment of the skin.
How men describe it: "It sags," with the nipple pointing downward.
What is usually present: Large volume, excess skin and a lowered nipple.
Typical approach: Removal of excess skin and repositioning of the nipple, in addition to addressing the tissue.
Yes. One-sided (unilateral) gynecomastia accounts for about one in four cases. Having it on a single side is not a reason for embarrassment, and the plan should still be built around an in-person evaluation rather than a photo or a self-assessment.
The grade describes the size and shape of the chest, but it does not, on its own, tell you what the tissue is made of. Three situations are common:

Your grade influences several parts of your plan:
Online descriptions and photos can help you recognize yourself, but your grade is confirmed during an in-person examination. During your consultation, Dr. Gargiulo examines your chest, assesses how much of the fullness is gland and how much is fat, evaluates skin elasticity and nipple position, and reviews your health history. Based on that evaluation, he explains which technique fits your chest and what your recovery is likely to involve.
At AgeFocus in Southampton, NY, Dr. Juan Gargiulo, Cosmetic Surgeon and Medical Director, performs awake gynecomastia surgery without general anesthesia. Through small incisions, he removes excess glandular tissue and fat. Because the patient is awake, he can make adjustments based on the patient's feedback and seated position. Excess skin is addressed only when needed.
Dr. Gargiulo personally performs every procedure, and he determines your grade and the right technique during your consultation.
Gynecomastia ranges from mild puffiness behind the nipple to a chest with excess skin and a lowered nipple. Understanding the four grades helps you put words to what you see in the mirror and gives you a clearer idea of what treatment may involve. Only an examination, however, can confirm your grade and the plan that fits your chest.
