In our clinical trial, we asked patients if they had an indentation or hourglassing deformity in the shaft of their penis. After twelve weeks of use, 52% of those men indicated their indentation or hourglassing improved. They characterized the change as either significant (7%), moderate (50%), or minimal (43%).
After 36 weeks of use overall response improved with 42% of men (as opposed to only 7% at 12 weeks) indicated the improvement was significant, 33% moderate and 25% minimal.
Measuring changes in indentation our hourglassing is very difficult so the trial relied on subjective reporting from the patient. While we hope this information is helpful it should be noted that not all men have the same definition of significant, moderate or minimal.
