. The nocturnalpeniletumescence (NPT) test measures night‐time erectile events where a man should achieve about three to five penile erections per 8 hours of sleep.26 At present, there is a lack of consensus on acceptable NPT parameters to define true ED because the duration and intensity of nocturnal erections are likely related to the patient’s age, the environment of the NPT study, and the patient’s mental
, objective endpoints to discriminate between psychogenic and organic ED include nocturnalpeniletumescence testing or penile duplex Doppler ultrasonography (19, 20). Questionnaires, including the frequently employed IIEF, may not always successfully differentiate between psychogenic and organic causes (20, 21). Indeed, in two studies each with 36 and 44 patients, 20%–37% of patients who scored severe ED
hemoglobin A1C, fasting glucose and lipid profile should be considered to rule out occult diabetes and dyslipidemia. Patients with symptoms associated with testosterone deficiency or failure of phosphodiesterase type-5 inhibitors (PDE5is) should consider having a morning serum total testosterone level drawn41.

The international index of erectile function-5 (IIEF-5) score, erectile hardness score (EHS), nocturnalpeniletumescence and rigidity (NPTR) indexes (nocturnal penile erection frequency, total duration of penile erection, duration of penile head hardness ≥60%, duration
The value of shear wave elastography combined with red blood cell distribution width in evaluating arterial erectile dysfunction. A retrospective study was conducted to determine the value of shear wave elastography (SWE) and red blood cell distribution width (RDW) in the diagnosis of various forms of erectile dysfunction (ED). With the method of NocturnalPenileTumescence and Rigidity (NPTR
. All erectile dysfunction (ED) patients underwent sleep monitors using Fitbit Charge 2™ (Fitbit Inc.) and nocturnalpeniletumescence and rigidity (NPTR) monitors using RigiScan® (GOTOP medical, Inc., USA) for two nights. Subsequently, the patients were divided into two groups: Group A included patients who experienced effective erections only on the second night, while Group B included patients who

If there is any evidence of hypogonadism or the dysfunction is particularly consistent at a young age, then further hormone evaluation is obligatory.2 Advanced testing with nocturnalpeniletumescence studies and vascular evaluation with sonography, and other tests are somewhat subjective and rarely provide useful information except in cases of trauma or other vascular
, infection, hemorrhage, or cicatricial retraction were observed. The patient's erectile function was satisfactory, and his international index of erectile function-5 score (IIEF-5 score) was 23 at the 24-month follow-up visit. Additionally, the presence of nocturnalpeniletumescence demonstrated that he had normal erectile function. This procedure is an effective surgical option for men with complete

Changes in penile length, testosterone level, International Index of Erectile Function-5 (IIEF-5) questionnaire, Quality of Erection Questionnaire (QEQ), and nocturnalpeniletumescence (NPT) testing were used
, measurement of nocturnalpeniletumescence (NPT), ultrasound assessment of the cavernous arteries with the further estimation of their endothelial function. In addition to the expected improvements in exercise tolerance, regular cycling exercises led to a significant recovery of erectile function (number and duration of NTP, increased penile blood flow volume, estimated during NTP measurement), improved
Nocturnal penile erections: A retrospective study of the role of RigiScan in predicting the response to sildenafil in erectile dysfunction patients Sildenafil enhances the nitric oxide-cGMP pathway of erection, which is claimed to have a role in nocturnalpeniletumescence and rigidity (NPTR). This study aimed to find whether RigiScan can predict the response to sildenafil among erectile
to evaluate erectile function of patients and employed diffusion MRI and graph theory to construct brain networks of 21 pED patients and 24 healthy controls. We considered four nodal metrics and their asymmetry scores, and nocturnalpeniletumescence (NPT) parameters, to evaluate the topological properties of brain networks of pED and their relationships with the impaired self-reported emotion and erection
[Effects of different medications with tadalafil on erectile dysfunction in males with primary sexual failure]. To evaluate the effects of three different medications with tadalafil on erectile dysfunction (ED) in young men with primary sexual failure. This study included 76 male ED patients aged 21－35 years who had primary sexual failure but normal nocturnalpeniletumescence and rigidity
. The secondary outcomes revealed no significant changes in number of events, tip rigidity, or duration of best episode between pre- and postoperative nocturnalpeniletumescence test (on RigiScan) in group 1, but a slight decrease in group 2 (P <.05). The limitation was the small sample size and heterogeneous population. NTSAU is a safe, feasible, minimally invasive procedure for PFUI, optimizing erectile
