cGMP
is an abbreviation for cyclic guanosine monophosphate.
cGMP causes the smooth muscles lining the arteries of
the penis to relax thereby allowing blood to flow in
and cause an erection; cGMP however is broken down by
PDE 5. An upset in the correct balance of the cGMP and
PDE 5 can result in impotence. Prostate cancer treatment
has been associated with the occurrence of impotence
after treatment, however, prostate cancer treatments
are continually advancing in technique and technology
that may result in fewer and less severe side effects.
