Extension strategy requires establishing prolonged conditions for traction (lengthening) of penis with equal force, which can be achieved by the lengthening of the extender’s bars in equal periods. According to the standard instructions, an extender is used with the same bar length during 7-10 days. The process is kept under control by means of a ruler or by turning extending bolts onto the bars. Thus, prolonged conditions for static extension of tissues are created.
Each 7-10 days the bars should be extended by 5 mm, which is indispensable to exceed the extending of penis tissues within any given stage and to provide further extension. Besides, some extender manufacturers recommend wearing the device on a deliberately shorter length than the one of a maximally extended penis, allowing for a necessary period of “adaptation”.
