Active clinical trials for "Erectile Dysfunction"

This study evaluates the retinal and choriocapillary vascular features in patients under the effects of Tadalafil 20mg for more than 6 months, using optical coherence tomography angiography.

The purpose of this study is to determine which technique in using a vacuum erection device (VED) is best. Erectile dysfunction (ED) after robotic prostate cancer surgery is a concern for both the surgeon and the patient. Recent studies have shown that beginning to use the vacuum pump on a daily basis starting with in 2-8 weeks may help prevent the start of penile shrinkage. This is a potential issue that can occur because of decreased blood flow after prostate cancer surgery. This study will allow researchers to determine and compare vacuum therapy techniques and erectile function outcomes of patients who have prostate cancer surgery

The purpose of this study is to find out if androgen deficiency (low levels of testosterone, a male hormone produced by the sex glands) and erectile dysfunction (sexual dysfunction) will predict over time the development of a heart attack, stroke, or death in men with Diabetes Mellitus who have angiographically proven coronary artery disease (CAD) (≥50%) with or without percutaneous coronary intervention (PCI). A substudy aims to show the different factors and processes that may show a relationship between sexual function and levels of androgen in the body to heart disease.

This study will evaluate if an orally disintegrating tablet of sildenafil will have similar pharmacokinetic properties when given with food and without food.

The purpose of this study is to explore patient and partner experiences with sexual dysfunction following radical prostatectomy, in order to understand its effects on sexual and non-sexual intimacy. This will enable us to provide assistance in the future to individuals experiencing similar circumstances.

This study evaluates the retinal and choriocapillary vascular features in patients under the effects of Tadalafil 20mg using optical coherence tomography angiography.

Main object is to investigate the safety profile of Levitra in combination use with alpha-blockers in patients with erectile dysfunction used in clinical practice after launch. In the initial combination date and the first and second observation after initial combination date, number of tablets prescribed, dose of tablets and number of tablets taken until follow-up visit will be investigated. The efficacy and tolerability will be evaluated at 2 months after initial combination date.

The purpose of this observational registry is to collect and better understand "real-world" outcomes for men undergoing penile implant surgery to treat erectile dysfunction.

This is a pilot study designed to answer the question " Do men who are receiving methadone maintenance therapy have lower spinal bone densities compared with age-matched controls who are not receiving methadone therapy?" The primary aim is to assess whether the mean or median spinal dual-ray energy x-ray absorptiometry (DEXA) scan results are different between these two groups of male patients. Primary measurements include: spinal bone densitometry by DEXA scan. The secondary aim is to examine the role of sex steroids in men receiving methadone maintenance therapy and their association with spinal bone density and sexual dysfunction. Secondary measurements include: serum testosterone, estradiol, lutenizing hormone, albumin, sex hormone binding globulin and Vitamin D levels; age; Brief Sexual Function Inventory; Dietary, smoking/alcohol use and physical activity; Medical history, surgical and medication use; length of time using illicit opiates and time on methadone maintenance therapy.

The purpose of this study is to evaluate the safety and effectiveness of the drugs yohimbine and naltrexone in treating men with erectile dysfunction (ED) (the inability to achieve or maintain penile erection for satisfactory sexual performance). ED is a medical and psychological problem that is usually associated with increased age. Evidence suggests that specific neurotransmitter systems are involved in the regulation of sexual function. Yohimbine and naltrexone are drugs that may influence these neurotransmitter systems. This study will use different doses of yohimbine and fixed doses of naltrexone to determine their effectiveness in treating ED. Participants in this study will be screened with a medical history, physical examination, blood and urine tests, and an electrocardiogram (ECG). The study will consist of three outpatient visists.
