The male breast is less representative than the female breast but, during puberty, adolescence and adulthood, it can increase in volume giving rise to what is called gynecomastia.
Gynecomastia can be divided into three forms:
- true gynecomastia: the increase in breast volume is caused by the increase in the glandular component;
- adipose gynecomastia: the increase in breast volume is caused by the increase in adipose tissue in the breast area;
- mixed gynecomastia: the increase in breast volume is caused by the increase in the glandular component associated with an increase in the distribution of breast tissue; very frequent in formerly obese people.
