A small percentage of men in a prostate cancer study complained that their penis seemed shorter following treatment, with some saying that it interfered with intimate relationships and caused them to regret the type of treatment they chose. Complaints were more common in men treated with radical prostatectomy (surgical removal of the prostate) or male hormone-blocking drugs combined with radiation therapy, according to the study by researchers from Dana-Farber/Brigham and Women’s Cancer Center (DF/BWCC). No men reported a perceived shortening of their penis following radiation therapy alone.
