🔎 Quick Summary
Gynecomastia is the enlargement of male breast tissue due to hormonal imbalance, and it is different from simple fat accumulation.
1️⃣ Introduction
Gynecomastia refers to the enlargement of breast tissue in males.
It can affect one or both sides and may cause concern or embarrassment.
👉 It is important to understand that gynecomastia is a medical condition and is often related to hormone balance.
2️⃣ How it happens
Breast tissue growth in males is influenced by hormones:
• testosterone (male hormone)
• estrogen (present in small amounts in men)
Gynecomastia occurs when:
• testosterone levels decrease
• or estrogen levels increase
👉 This imbalance allows breast tissue to grow.

• tenderness or sensitivity
• a firm or rubbery lump under the nipple

👉 The lump is usually located beneath the nipple.
