A snipet of news to toss by your urologist.

A small study by Frank Sommer, Professor of Urology at the University
of Cologne, Germany presented at the American Urological Association
meeting, shows normal erectile function restored in >50% of subjects
after using a nightly 50mg dose of Viagra.  The patients selected for
the study had organic etiologies for erectile function or a mix of
organic and psychogenic factors.  The study did not include patients
with pure psychogenic ED.  The article did not state whether any
patients had been treated for PCa.

The concept of daily treatment at bedtime arose from the recognition
that nocturnal erections occur at all ages and contribute to the
maintenance of the integrity of smooth muscle cells in the corpora
cavernosum.

The study consisted of 84 men (mean age 47.1 years) with ED lasting
longer than six months.  The patients were randomly assigned to receive
50 mg of Viagra evey night before bedtime or 50 to 100 mg of Viagra,
taken in the conventional on-demand manner.  Treatment continued for 12
months.  Primary efficacy measures were the erectile function domain
score on the International Index of Erectile Function (IIEF) and peak
systolic velocity (PSV) of the penile arteries at 1 and 6 months after
discontinuation of therapy.  At the end of treatment, 22 of 34 treated
nightly and 21 of 32 treated on demand had normal erectile function by
IIEF criteria.  There was no mention of what happened to the missing 18
men.  One month after discontinuation, 20 of the nightly group had
normal erectile function whereas only 3 of the on-demand group had
normal erectile function.  At six months after discontinuation, 19 of
the nightly group still had normal erectile function, 55.9% of the 34
men on nightly doses.
