The literature search did not show any studies reporting normal values on penile sensorial EMG in a healthy male. Additionally, another limitation is the absence of any data on the effects of socioeconomic status on penile sensation in our study.
We demonstrated a direct correlation between improvements in IIEF-5 scores and NCV values with the use of daily tadalafil and showed that age is a factor affecting the improvement in penile sensorial EMG findings.
We interpreted that tadalafil exerts its effects on erectile sensation by preventing the development of apoptosis in corporal sinusoids, preserving the proportion of smooth muscles and reducing pro-inflammatory cytokines.
(p<0.001, p<0.001, p=0.010 for ≤50 years of age; and p<0.001, p=0.012, p=0.030 for >50 years of age, respectively). There was a comparable improvement in the IIEF score in both age groups (p=0.314), whereas there was a statistically higher improvement in NCV and latency values in the group aged ≤50 years (p<0.001, p=0.001, respectively). A significant correlation was observed between the IIEF score and EMG findings. There was a significant correlation between IIEF and NCV (r=0.663, p<0.001) and Amplitude (r=0.659, p<0.001). Our study has some limitations, including the absence of data on normal values in penile sensorial EMG in individuals with normal erectile function. Cialis Daily is an expensive brand name drug to treat Erectile Dysfunction. Unlike other ED meds, there’s no planning required allowing you to be spontaneous and ready anytime.

Normally distributed data were presented as mean + standard deviation, while non-normally distributed data were presented as median and IQR (25-75th). An independent simple t-test was used to compare two independent normally distributed data, while the Mann-Whitney U test was used for the comparison of non-normally distributed data. A paired sample t-test was used to compare two independent normally distributed data, while the Wilcoxon test was used for the comparison of non-normally distributed data. Spearman’s Correlation analysis was used to analyze the parameters related to changes in IIEF scores. A p-value of <0.05 was considered statistically significant.
Analysis of the dataset was carried out using the IBM Statistical Package for Social Sciences version 23.0 (IBM SPSS Corp.; Armonk, NY, USA). One patient discontinued the treatment with the complaint of myalgia, and the study was continued with 28 patients since another patient did not come to the follow-up visit. The mean age of the patients was 53±9 years. The mean duration of ED was 6.8 months. There were 8 (29%) patients with diabetes and 7 (25%) patients with hypertension. Brand-name Cialis is made by Lilly.
The demographic characteristics and comorbidities of the patients are given in Table 1. We showed statistically significant changes in pre-treatment and post-treatment IIEF-5 scores and penile sensorial EMG findings. Pre-treatment IIEF-5 scores of 13±3 were measured as 19±3 after treatment with tadalafil at a daily dose for 12 weeks (p<0.001). This improvement was consistent with the literature. The mean nerve conduction velocities (NCV) in EMG was 35.5 m/sec (33.3-41.2) before treatment, and 38.05 m/sec (34.5-43.6) after treatment (p<0.001).
The increase in NCV is the most important finding of penile sensorial EMG showing an increase in penile sensation. Thus, the increase in NCV has been interpreted as an improvement in penile sensation. The changes in latency and amplitude values used in the calculation of NCV are given in Table 2. The delta equation (Δ = the amount of change) was created for the IIEF-5 score and penile sensorial EMG findings as post-treatment value minus pre-treatment value. Factors that may be related to this change were evaluated. Generic Tadalafil or Generic Cialis Daily is also approved by the FDA to treat ED and is much more affordable. Generic Cialis has exactly the same active ingredient and is just as effective. Cialis Daily allows you to be spontaneous and ready to have sex anytime in a way that other ED medicines don’t.
We also showed an increase in NCV after 12 weeks of daily treatment with tadalafil compared with pre-treatment values. The mean NCV in EMG was 35.5 m/s (33.3-41.2) before treatment, and 38.05 m/s (34.5-43.6) after treatment (p<0.001). (20) showed a reduction in proinflammatory cytokines in rats with a 12-week high-dose tadalafil therapy. (21) compared patients with vasculogenic ED and non-vasculogenic ED, both treated with tadalafil. They have demonstrated the therapeutic effects of tadalafil on non-vasculogenic ED.
(22) showed that long-term tadalafil therapy in diabetic rats partially reduced penile oxidative stress lesions through a local antioxidative stress pathway. Accordingly, they reported that the initiation of long-term once-daily tadalafil therapy immediately after the diagnosis of DM may partially prevent the development of diabetic ED in rats. In our study, we examined patients who received 12 weeks of tadalafil therapy regardless of the cause of ED and performed IIEF scoring and penile sensorial EMG examinations before and after treatment. A significant correlation was observed between the IIEF score and penile sensorial EMG findings. A statistically significant improvement was observed in IIEF, NCV, and latency values in both age groups. If that’s as important to you as it is to many other men, then Cialis Daily can be a great option.
A two-channel electroneuromyography device (Nihon-Kohden-Neuropack, model MEB-2200) was used for recording. Penile sensorial EMG was examined using Clawson’s method. The penis was placed in the concavity of a specially designed Orthoplast penile traction device and stretched to reach its maximum length by pulling from the tip of the glans. A Cunningham incontinence clamp was placed on the glans, and the penis was maintained in tension by holding from the glans. An electroencephalography paste was used for the placement of active and reference steel electrodes.
The active recording electrode was placed as proximal as possible to the root of the penis. The reference electrode was placed 4 cm above the active electrode. The proximal part of the dorsal penile shaft was stimulated orthodromically with an active electrode and the dorsal glans with a reference electrode (15). Categorical data were presented as number and percentages. Continuous data were evaluated by the Kolmogorov-Smirnov test to verify the normality of the distribution of variables. Cialis Daily is a 5mg tadalafil pill that you take every day.
| Medication | Duration of Action | Frequency | Side Effect Profile | Cost (approx.) |
|---|---|---|---|---|
| Tadalafil | Up to 36 hours | Daily/As needed | Mild, fewer headaches | $10/tablet |
| Sildenafil | 4-6 hours | As needed | Headaches, flushing | $6/tablet |
| Vardenafil | 4-6 hours | As needed | Less flushes | $8/tablet |
Because it’s a daily pill, it’s a lower dose than Cialis 10mg or Ciails 20mg which men take as needed. By taking the pill every day, you constantly have a sufficient quantity of tadalafil in your body that it should help with your erection whenever you have sex. By comparison, you need to take other ED medicines - including Cialis 10mg and 20mg - before sex, so in that sense they require a level of planning that isn’t necessary with Cialis Daily.
In our study, we performed sensorial measurements in patients with ED. Penile sensorial EMG can provide valuable additional information in the differential diagnosis of ED, particularly allowing the identification of different neurogenic lesion sites (16). (17) injected intracavernosal papaverine in 15 patients with ED and compared the results of penile EMG and biopsy examinations. They demonstrated low -amplitude values in 5 patients with diabetes mellitus. Penile sensorial EMG is a less-invasive, valuable method for patients with ED, whereas penile biopsy examination did not reveal any specific results.
Kayigil and Ergen (18) reported lower amplitude values in the EMG of the corpus cavernosum (CC-EMG) in 45%-65% of patients with ED. (19) included 24 patients, 16 with normal findings on neurological examination, and 8 with diabetic neuropathy. They investigated the sensory conduction velocity in the dorsal penile nerve at rest and after injection of prostaglandin E1. They reported that the mean NCV values increased from 32.3+/-6.7 m/s to 47.4+/− 8.2 m/s after the injection of prostaglandin E1. They also reported an increase in NCV in patients with improvement in ED.

There was a significant correlation between age and IIEF-5 score and penile sensorial EMG findings. There was a significant correlation between the IIEF-5 score and NCV (r=0.663, p<0.001) and Amplitude (r=0.659, p<0.001). As improvement in IIEF-5 increases, so does improvement in NCV and Amplitude (Table 3). The mean amplitude value in penile sensorial EMG was 4.47±1.32 before treatment, whereas it increased to 5.07±1.60 after treatment (p<0.015). Additionally, the mean latency value was 2.14±0.42 before treatment, whereas it increased to 2.32±0.38after treatment (p<0.001).
The latency and amplitude parameters in the penile sensorial EMG are used to calculate NCV. The increase in these values after treatment was interpreted as an improvement in penile sensation. As a result, it has been shown that the improvement in IIEF-5 provides an improvement in penile sensation (Figure 1). Currently, PDE-5 tadalafil over the counter uk inhibitors are used as first-line therapy in patients presenting with ED. Our literature search did not find any studies reporting normal values of penile sensation during a normal erection.
