Nocturnal erection detection with the outdated RigiScan is the golden standard for erectile dysfunction (ED) nature differentiation. The Staying Hot and Feeling Hot study have shown that nocturnal erection detection is feasible with patient-friendly overnight penile temperature measurements. The question has arisen whether the penile temperature methodology is also capable to detect the absence of nocturnal erections, which is essential for clinical implementation in erectile dysfunction diagnostics. The objective of the MENDiP-study is to determine the feasibility to detect the absence of nocturnal erections with overnight penile temperature sensors. Furthermore, the MENDiP study functions as a first pilot trial to investigate the effect of age on the penile temperature during nocturnal erections in test subjects with normal erectile functioning. This is done in an observational study with a longitudinal design in which pre- and postoperative ambulatory overnight measurements are performed in patients, aged 55 - 70 years with preoperative normal sexual functioning, undergoing a non- or unilateral nerve-sparing robot assisted radical prostatectomy.
1- To evaluate the effect of using tadalafil 5mg/day or sildenafil 25mg/day in the treatment on these ratios and its clinical effect in erectile dysfunction patients.
We designed a double blind randomized sham-controlled trial in order to investigate and compare the treatment efficacy of LiST plus PRP intracorporeal injection vs LiST plus placebo (normal saline intracorporeal injection) in men with moderate and mild to moderate vasculogenic ED, as measured by IIEF-EF.
Objectives: To perform pilot study using unilateral transcutaneous electrical stimulation (TENS) on thegenital nerves (dorsal nerve penis and cavernous nerves) for improving of the intracorpereal pressure and full penil erection in men after exclusion neurogenic, endrogenic and earteriogenic disorders. The investigators hypothesize that this therapy will be effective at improving erectile dysfunction (ED). Material and methods: The study will comprised 20 patients with ED randomized in two groups. Two adhesive skin electrodes are placed, one at the root of the penis and near the pubic symphysis as a cathode, and a second 2-3cm lateral to the penis. Stimulation is delivered for 30 min at the maximal tolerable stimulation amplitude at 210μs pulse width and in one group with a pulse rate at 20Hz, the second group at 60Hz. The penile tumescence and rigidity observed during stimulation are recorded in both groups of patients. Erection Harness Score (EHS) and Quality of Erection Questionnaire (QEQ) are assessed at baseline, immediately after stimulation and 2 weeks after stimulation.
The purpose of this study is to evaluate the efficacy and safety of Toronto association in the treatment of both sexual dysfunction: erectile dysfunction and premature ejaculation.
This is a Phase II, randomised, double-blind, parallel-group, placebo-controlled study to investigate the effects of repeat single oral doses of IPED2015 in otherwise healthy male subjects with ED. Up to 120 subjects are planned to be enrolled into 3 groups. Group 1 is planned to consist of 60 subjects, Group 2 is planned to consist of 36 subjects and Group 3 is planned to consist of 24 subjects. Groups 1, 2 and 3 will be conducted in parallel. Each subject will be dosed on four occasions. There will be three study treatments of dose 1 of IPED2015, dose 2 of IPED2015 or matched placebo. In each group, subjects will be randomised evenly to each of the three study treatments and will receive the same treatment on each visit.
This is a randomized, open-label, single-dose, five-period crossover, relative bioavailability study to evaluate tadalafil gummy 10mg and tadalafil oral tablets 10mg in healthy volunteers
Hong Kong has an aging population. By the year of 2036, more than 30% of our population will be older than 65 years old1. Aging in male has been shown to correlate with the risk of erectile dysfunction(ED). The demand in ED treatment is expected to increase. Several ED treatment options are available, ranging from oral or intracavernosal drug treatments, to vacuum erection therapy or even penile prosthesis implantation. However, none of these treatment are curative nor rectify the pathophysiology of ED. Low-intensity extra-corporeal shockwave therapy(LI-ESWT) has been introduced since 2010 for treatment of ED. The first randomized-controlled trial by Vardi et al. had proved the efficacy of ESWT in improving the International Index of Erectile Function(IIEF) score3. The International Index of Erectile Function-Erectile Function domain score(IIEF-EF) was significantly greater in the treatment group compared with the sham therapy group. The efficacy of LI-ESWT was also confirmed in meta-analyses. Nonetheless, the available studies were criticized for the variations in shockwave generators, energy parameters and treatment protocol. Most studies used focused electrohydraulic machines, did not include NPT as part of the outcomes assessment, and only reported the short-term outcomes. Currently LI-ESWT machine was used in few Hong Kong public hospitals for the treatment of erectile dysfunction. In KEC, few pilot cases have been done using the linear LI-ESWT machine. No adverse events were seen. Local published data is lacking. Yee et al. has published a double-blinded randomized placebo-controlled trial on LI-ESWT in 20144. Using an electrohydraulic machine with a focused shockwave source, they concluded no significant differences in IIEF-EF and Erectile Hardness Score(EHS) between treatment and sham therapy after 13 weeks of treatment. In subgroup analysis significant improvement was noted in men with severe baseline erectile dysfunction (LI-ESWT IIEF-EF improvement: 10.1 ± 4.1 vs sham therapy IIEF-ED domain improvement: 3.2 ± 3.3; P = 0.003). There were several limitations in this study. These include the small number of participants included in the subgroup analysis (ranges from 18 to 21 men in each subgroups), the lack of physical measurement of erectile function. The percentage of patients with 5 points or more IIEF-EF improvement and the Erection Hardness Score(EHS) were also not reported. They have also used an old design with focused energy source, instead of the linear energy source. In light of the limitations of the previous international and local studies, the investigators plan to investigate the efficacy of a linear electromagnetic LI-ESWT machine in men with moderate and severe ED. In addition, the intermediate-term outcomes would be studied, in terms of patients-reported erection scores and nocturnal tumescence and rigidity measurement.
The purpose of the study is to determine the effects of testosterone treatment on erectile function, fatigue, depression, cognitive function, quality of life, urinary incontinence, pain, and damage to neurons in male Multiple Sclerosis patients with low testosterone, using questionnaires, blood samples and a rectal exam in volunteers 55 years and older.
