Claims are often made that a fat transfer to the penis will provide a permanent result, however, this is misleading. A small amount of the fat transferred to the penis may survive for a long time, however, any permanent size gain is most likely to be in the form of hard nodules of necrotic fat with calcification. In almost all cases a fat transfer will need to be repeated a number of times in order to smooth out irregularities and maintain any increase in size.
