Active clinical trials for "Erectile Dysfunction"

We investigate the potential pharmacokinetic drug-drug interaction between Tadalafil and Tamsulosin in healthy male volunteers who receive Tadalafil alone, Tamsulosin alone, and both together in a 3 period repeatedly.

The aim of the present study is to study the influence of periodontal therapy (non-surgical) on the severity of erectile dysfunction(ED) among patients with chronic periodontitis and moderate or severe ED.

The investigators know that treatment for prostate cancer and erectile dysfunction can impact sexual health and quality of life. They want to learn how the treatment affects one's emotional and social well-being. They have developed a new type of counseling. Cancer patients seek counseling for lots of reasons. It often helps them cope because they can express their feelings with a trained professional. They hope that this counseling will teach patients skills that they can use to comply with erectile treatment programs, improve their sexual health and quality of life. These skills may also improve physical and emotional well-being. As part of this study they will ask the patient to provide feedback on the proposed counseling.

The purpose of this study is to investigate if treatment in erectile dysfunction with a long-acting drug (Tadalafil) taken once a day or taken as needed results in a longer treatment adherence and better long term outcomes (over 24 weeks), compared with a short-acting drug (Sildenafil Citrate) taken as needed.

To compare men of different races and those with diabetes or depression to white men that do not have diabetes or depression but also suffer from the inability to get or keep an erection.

This is a study consisting of four periods (screening, run-in, treatment, follow-up). A four-week treatment-free, run-in period where the subject will make at least four attempts at intercourse on four separate days with at least 50% of the attempts must be unsuccessful. During run-in the subjects will be using a stopwatch to measure the time from erection perceived hard enough for penetration until withdrawal from the partner's vagina. Next there are 12 weeks of treatment with either placebo or LEVITRA. Each subject will be required to visit the clinic on 5 occasions over a period of 4 months.

Autologous adipose-derived regenerative cells (ADRC) extracted using Celution 800/CRS System (Cytori Therapeutics Inc) from a portion of the fat harvested from the patient's front abdominal wall. ADRC will be administered one-time intracavernosally. This is a single arm study with no control. All patients receive cell therapy.

Urinary incontinence and impotence are typical disturbances after radical prostatectomy. Although, several surgical methods are developed to decrease these disturbances, 8% and 50% of the patients suffer from permanent urinary incontinence and impotence, respectively. Previously two studies have shown that endopelvic fascia preservation may decrease postoperative incontinence and impotence rates. Unfortunately these studies are retrospective decreasing their reliability. The present study is prospective and randomized clinical trial. The investigators are going to randomize 180 patient to preservation and opening the endopelvic fascia groups. Functional and oncological results are followed up to 1 year after surgery.

The primary objective of this study is to evaluate whether, after two 8-week treatment periods, male patients with erectile dysfunction (ED) in China prefer 20 milligram (mg) tadalafil or 100 mg sildenafil. This trial consists of two treatment periods of 8 weeks each and an extension phase of 8 weeks, for a total of 24 weeks.

Sildenafil (Viagra(R))is widely used by men with Parkinsons Disease (PD) and erectile dysfunction. A number of patients have reported that when they take Sildenafil, their need of anti-PD medication is reduced. We hypotheses that sildenafil increases brain blood flow and hence improves the function of specific brain regions, improving motor function. Motor function and cerebral blood flow of 8 patients will be tested before and after Sildenafil intake and before and after anti-PD medication.
