Gynaecomastia is enlargement of the breast tissue in males and is more popularly called MAN’s BOOBS. It is caused by the proliferation of glandular tissue rather than fatty proliferation and presents as a rounded mound of tissue spreading into the breast from underneath the nipple.

2. Puberty: 48-64% of boys at puberty have gynaecomastia with a peak age o between 13 and 14 years, followed by a decline in late teenage years.

3. Old age : Most commonly seen among men aged 50-80 years.
