A retractive (retreating respectively reducing in size) penis is permanently shorter when compared to its former length or has a significantly reduced volume (optically or anatomically shrunken). The elongation of the penis by means of a  penis expander counteracts a retraction process.

For example, the penis can be reduced in size on the basis of the following
