Scott, The breast is a modified sweat gland. Under the influence of female hormones it develops into a functional structure. During puberty it is not unusual for boys to develop some breast tissue also, but when they fully develop their male hormones the breast tissue regresses. An adult male can develop breast tissue if there are female hormones,such as estrogen, present. If an adult male takes estrogens he will develop breast tissue.If there is an abnormal production of estrogenic substances he will develop breast tissue. When men used to carry their pack of cigarettes in the shirt pocket over the left breast, the rubbing on the nipple would sometimes result in breast enlargement on the left side only. The medical term for breast development in males is "gynecomastia". If an adult male has gynecomastia he should see his doctor or a specialist in hormonal problems. These doctors are called "Endocrinologists". WMR
