In summary, the main mechanism of RES is the upregulation of BDNF and its receptor, tyrosine kinase B (trkB), in motor

Evaluating and Treating Erectile Dysfunction

It employs negative pressure to dilate the cavernous venous sinus, increase the perfusion of cavernous artery and venous blood, and ultimately achieve the goal of producing penile erection. An external constriction ring is placed at the base of the penis to prevent blood flow during intercourse in order to maintain an erection, but the ring should not be placed for more than half an hour (Yuan et al., 2010; ). It is used to promote the recovery of penis function and maintain penis length (). had demonstrated that the erectile response induced by the vacuum erection device may increase the smooth muscle/collagen ratio by decreasing hypoxia-inducible factor-1 and transforming growth factor-1, thereby improving penile blood flow (Yuan et al., 2010; ). In addition, the device can only increase the oxygenation of the corpus cavernosum without the use of a shrink ring.

Age-related demographics

This method can bypass the limitations of oral drugs and directly achieve an artificial erection, but it requires a normal and intact cavernous nerve to produce an erection (; ). Compared to other penile rehabilitation therapies, VED therapy has the advantages of being non-invasive and having fewer systemic side effects (; Sultana et al., 2022) (Figure 2). The study by Sherry A Beaudreau et al. found that the correct use of the device resulted in an erection to complete normal intercourse in 90.7% of patients (49 of 54 patients), all of whom indicated that they would recommend the device to other ED patients. Approximately 93.9% of patients reported that their quality of sex life was satisfactory or very satisfactory after treatment with the VED (). neurons (; ), BDNF and the binding of trkB can promote nerve regeneration and the recovery of damaged nerve function ().

() initially investigated the effects of FES ed tablets on ED.

Why Are My Erections Getting Weaker?

Regular use of VED in the early postoperative period has been verified to be beneficial for the preservation of penile length (). ()study included 50 patients with type I and type II diabetes ED, treated with VED and found that 85% of patients had positive returns. Therefore, VED therapy can be used as an alternative to pharmacotherapyz (; ). Some studies have shown libido booster women that VEDs can also be used in combination with laser illumination and are more effective than either alone (). VEDs are non-invasive and very effective in treating ED and improving sexual partner relationships, with a high success rate and very few side effects (), particularly in patients with ED after radical prostatectomy.

The Link Between High Blood Pressure and Erectile Dysfunction

In ED patients after radical prostatectomy, early treatment with VED can significantly improve erectile function (Qin et al., 2018b). Common adverse effects of VEDs include penile contusion due to improper use, especially in patients who are taking or have recently taken anticoagulants, penile numbness and/or pain, penile coldness, and ejaculation disorders (). The device may also cause some psychological discomfort to the patient, such as frustration and feelings of lack of autonomy. Therefore, combining negative pressure suction device treatment with psychotherapy will be more effective. Moreover, the optimal duration of VED treatment for ED, the oxygen saturation in the cavernous body during treatment, and other factors need to be further studied. They found that after 4 weeks of FES treatment, the patients’ IIEF-5 and Erection Hardness Score (EHS) significantly improved, indicating that FES had a positive therapeutic effect on ED.

What are the symptoms of erectile dysfunction?

Some scholars believe that ES can stimulate peripheral nerve regeneration (Willand et al., 2016), which can dramatically improve the recovery of nerve function, and improve ED symptoms in turn. Regenerative electrical stimulation (RES) can treat ED patients with cavernous nerve damage through promoting nerve regeneration and restoring damaged nerve function (). For example, in a study of a rat model of ED after nerve dissection, Shapira et al. found that short courses of electrical stimulation administered early in the course of nerve injury promoted recovery of nerve function (Shapira et al., 2019). found that RES after facial nerve injury in rats accelerated facial nerve function and improved regeneration of facial nerve-specific pathways, and that ES significantly increased brain-derived neurotrophic factor (BDNF) expression in the nucleus of the cell body of motor neurons after injury, promoting repair of damaged nerve cells (). ED, with nearly half of the patients in the trial regaining normal erectile function (Van Kampen et al., 2003).

compared the therapeutic effects of ES and aerobic exercise on ED and found that ES was significantly more effective than aerobic exercise in the treatment of ED (Rislanu et al., 2020). Based on summarizing the existing relevant studies and experiments, due to the continuous progress of current electrical stimulation, ES for ED has increasingly obvious advantages, including: a.

Suggested Reads about Erectile Dysfunction

In a study by Khayyamfar et al., the erectile success rate of the subjects reached 100%, and it is verified that VED is not affected by the etiology of ED (diabetic, venous occlusion dysfunction, arterial origin, etc.) in achieving erection (). Although most patients and their partners are satisfied with the device, studies had shown that the use of the device causes a lot of discomfort for some patients. For example, insufficient lubrication may lead to bruising of the penis, numbness and/or pain of the penis, cold sensation of the penis and inability to ejaculate (; ; ). About 25% of the patients in a study reported some physical discomfort during and after use of the device (). According to some studies, the negative pressure suction device also brings some psychological discomfort to patients, such as frustration and lack of autonomy (; ; ; ; Sultana et al., 2022).

4.1 VED

VED has become a common method of postoperative penile rehabilitation (). After radical prostatectomy, at least 85.8% of ED patients received penile rehabilitation, including VED (Tal et al., 2011; ; Zhang et al., 2022). Studies have demonstrated that ligation of the internal paraarteries of the genitals during radical prostatectomy may lead to nerve damage and decrease arterial inflow, which is a potential cause of ED after radical prostatectomy (; Zhang et al., 2022). In terms of efficacy, Dalkin et al. conducted a study of 42 patients who had undergone nerve-preserving radical prostatectomy and discovered that only one of 36 patients who received VED had a penis length reduction more than 1 cm. It is a simple and non-invasive physical therapy program (); b.

Clinically, ES treatment is much cheaper than other methods, and the patient compliance is relatively high ().

Helping Your Partner with Erectile Dysfunction

Electrical stimulation is one of the emerging technologies in clinical practice. It is a physical method that relies on the output of low-frequency pulsed current to treat diseases and is now widely used in urology, male surgery, gastrointestinal surgery, obstetrics, and gynecology, etc. Especially in the field of treatment of ED, increasing numbers of studies have shown that the use of electrical stimulation techniques for ED can achieve positive outcomes (Figure 3). According to some studies, the main principle of functional electrical stimulation for the treatment of ED include inducing penile endothelial proliferation and cavernous smooth muscle regeneration, promote NO release from cavernous endothelial cells (), and producing cGMP, which can relax cavernous smooth muscle and raise cavernous body pressure (). According to the current state of clinical research, most studies are limited to the efficacy of functional electrical stimulation (FES) on ED. a lack of sufficient clinical case verification (), the difficulty of applying individualized treatment for different causes.

Health History and Lifestyle

Invasive tests such as PPDU and Penile cavernosography, even if they are less traumatic to the patient, still add to the patient’s psychological burden and naturally have an impact on the diagnosis; other non-invasive tests are expensive and add to the patient’s financial burden. For the above-mentioned examination methods, the author prefers dual-energy CT. First, it is a non-invasive examination method. This ensures that the patient can face the examination with a relatively calm state of mind and will not have much influence on the accuracy of the examination results. Secondly, dual-energy CT takes less time, shortens the patient’s hospitalization period, and increases the patient’s medical compliance.

Finally, the accuracy and sensitivity of this test are high, which can accurately analyze the patient’s lesion site and give clinicians more precise guidance on the direction of treatment. Therefore, we believe that the future development direction of diagnostic technology needs to March in the direction of convenient, affordable, and non-invasive examination. With the development of image technology, CT imaging technology will be greatly improved, and CT examination is relatively convenient, inexpensive, and non-invasive, which should become the mainstream choice for diagnosing ED in the future. Currently, physical methods commonly used to treat ED include Vacuum erectile devices (VED), low-frequency electrical stimulation, low-intensity extracorporeal shock waves, Chinese acupuncture, and other treatment methods. Most VED consist of a shrink ring, a cylinder and a pump powered manually or super p force pill by battery power ().
