Cyclic
Guanosine Monophosphate is abbreviated
as cGMP. 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.
