There are currently several clinical trials under way for treating erectile
dysfunction (ED) caused by prostate cancer.

Trial 1

In this trial, the cheap generic substitute viagra
of nerve-sparing prostatectomy (surgical
removal of the entire prostate while preserving the erection-controlling
nerves), with and without nerve grafting, followed by standard therapy is being
examined. Participants will be in one of two groups: the first group will have
nerve-sparing prostatectomy with nerve grafting, then will use a standard
therapy such as Viagra, a vacuum constriction device, injection therapy, or
MUSE (erectile pill in urethra for erections) therapy. Participants in the second
group will have the nerve-sparing surgery without nerve grafting, and will use
the same standard therapy as the first group. The objectives of the study are
to compare the two types of surgery for effectiveness and their effects on
potency rates and erection quality in men with prostate cancer.

Trial 2

This study will be evaluating the effectiveness of Prograf, a medication
known to suppress the immune system, in the prevention of erectile dysfunction
in men who have had a nerve-sparing prostatectomy. Participants will be in one
of two groups: the first group will receive the active medication and the
second group will be given a placebo (sugar pill). The study will look at the
percentage of people who can achieve erectile dysfunction tabs
erectile function.

Trial 3

In the third trial, researchers are examining the effectiveness of erectile
dysfunction treatment with Viagra versus a placebo for men with prostate cancer
who have undergone radiation therapy and total androgen suppression. The
studies are attempting to determine if there is a difference in overall sexual
function and satisfaction between Viagra and placebo.

Trial 4

This study will be looking at the effects of radiation therapy, high energy
X-rays to destroy cancer cells, on erectile dysfunction. It will investigate
whether reducing the dose of radiation helps to prevent ED. Participants will
be placed into one of two groups: the first one will receive the standard
radiation therapy while the second one will receive a restricted dose of
radiation.
