People on this newsgroup love to use acronyms and medical slang just like
the doctors they spend so much time talking to. Pretty soon their
handwriting will go to hell also.

CU Medical Guide says that 60 to 90% of patients undergoing RP suffer
from ED. It notes that the nerves involved may heal, though very slowly.
Recovery may take up to two years and is unusual before 3 months after
surgery. CU also cites a British study that says regularly doing Kegel
exercises generally helps against ED; that report does not specifically
address ED caused by RP.

This source says that sexual impairment (i.e. impotency) risk is only
10% better if both nerves are spared and 7% if one nerve is spared (66%
if no nerve spared, 59% unilateral, 56% bilateral). Medicine is not
supposed to help in case both nerves are not spared for patients over 55.

Dr. Menon, on the other hand, claims that 82% of his institute's
patients 60 years of age had return of sexual function at six months.
Not sure whether he is much better at sparing nerves than others, but
the Adam numbers suggest that that by itself doesn't make that much of a
difference.

The Adam report puzzles me. Are the nerves not essential? Can you, at
least in theory, recover even if both nerves are not spared?
If so, does doing Kegels (presumambly to stimulate blood flow) speed up
recovery? Is Viagra or Cialis potentially helpful if at least one nerve
is spared, as in my case?
