Penile shrinkage,
also referred to as penis shrinkage, may be a side effect
of certain prostate cancer treatments. The radical prostatectomy
may cause a shortening of the penis. During the radical
prostatectomy, the doctor removes the prostate gland
as well as the portion of the urethra that runs through
the transition zone. The removal of part of the urethra
may shorten the length of the penis. Some doctors therefore
will recommend penile exercises to keep the penis malleable
and to decrease shortening and shrinking. Prostate cancer
treatment which uses androgen deprivation may cause
penile shrinkage which may be reversed after treatment
has stopped.
