Filter by:Because of the high incidence of post-radiation erectile dysfunction (ED), up to 72% after external-beam radiotherapy, this patient category represents a most difficult therapeutic challenge. Therefore, prevention of ED could be more effective than treatment. Tadalafil, a new phosphodiesterase type 5 inhibitor, has been recently introduced. No studies have investigated the efficacy of tadalafil in preventing ED in patients undergoing radiotherapy for prostate cancer. Efficacy of tadalafil can last up to 36 hours after intake. This will result in a prolonged and continuos enhancement of penile vascular responsiveness. This randomized, double-blind, placebo-controlled study has been designed to evaluate the efficacy of 20-mg of tadalafil administered for 12 months in maintaining erectile function of potent patients undergoing external-beam radiotherapy for prostate cancer.
The primary purpose of the study is to demonstrate that dapoxetine can prolong intravaginal ejaculatory latency time (IELT) compared with placebo in men with premature ejaculation (PE).
The purpose of the study is to characterize intravaginal ejaculatory latency time (time between the start of vaginal intercourse and the start of intravaginal ejaculation) in men with and without premature ejaculation (PE) and to assess the validity of patient-reported outcomes.
Androgen deficiency in the aging male is poorly understood. The objective of this study will be to determine the role of testosterone and DHEA in enhancing sexual interest and sexual performance.
- To evaluate the impact of nightly sildenafil vs placebo use on diabetic men with and without proven endothelial dysfunction and coexisting erectile concerns. - To determine if chronic sildenafil use compared to placebo positively impacts endothelial function among a cohort of diabetic mend with erectile dysfunction - To assess the salvage rate of sildenafil - failures who demonstrate improved response rates over time with chronic use - To assess if microalbuminuria predicts flow-mediated dilation (FMD) response - To measure and identify if other patient specific characteristics predict for sildenafil erectile response and flow-mediated dilatation (FMD) response over time (patient specifics; blood pressure, HBA1c, weight, BMI, age IIEF score at baseline)
The purpose of this study is to determine if treatment using a medication (anastrozole/Arimidex), which lowers estrogen levels in the blood is better than placebo, a tablet that does not contain any active medication, when combined with testosterone replacement to treat reproductive and sexual dysfunction in men with epilepsy. Anastrozole, the medication that is currently under study, does not, at this time, have FDA approval for use for this indication.
Assessment of duration of action, safety & toleration of different formulations and doses of UK-369,003 and Cialis in patients with male erectile dysfunction. Patients should have previously been on PDE5 inhibitors and have been respondents to the drug. Duration of treatment is 4 weeks.
Adult diabetic patients aged above 20 attending the diabetic clinic of National Taiwan University Hospital are invited to attend a face to face screening and interview. After obtaining the informed consent, questionnaires including IIEF, DAN-PSS-SEX and erectile dysfunction effect on quality of lie are filled.Personal data, status of diabetes control and complications of diabetes are recorded.The results will be used to investigate the prevalence of erectile dysfunction of diabetic men in Taiwan and erectile dysfunction related quality of life change.
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 study objective is to evaluate the effect that sildenafil citrate has on the hardness of erections in males with erectile dysfunction, based on subject responses to question 5 on the Event Log (hardness of erection) as measured at the end of double blind treatment (week 6).
