The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment 3D-Erect for erectile dysfunction?

Research on similar external vacuum devices shows they can help 87-89% of men achieve erections suitable for intercourse, improve sexual satisfaction, and have a high acceptance rate among users and their partners. ^{1 2 3 4 5}

Is the external device for erectile dysfunction safe for humans?

Research on vacuum constriction and external erection devices shows they are generally safe for treating erectile dysfunction, with studies focusing on patient satisfaction and low incidence of complications. ^{1 2 3 6 7}

How is the 3D-Erect treatment for erectile dysfunction different from other treatments?

The 3D-Erect treatment is unique because it is an external device that uses a computerized and programmable electronic vacuum mechanism to treat and prevent erectile dysfunction, offering a non-invasive and drug-free alternative compared to traditional medications or surgical options. ^{3 8 9 10 11}

Findings from Research

In a clinical trial involving 61 impotent men, the external vacuum erection device demonstrated an overall effectiveness rate of 67%, with 88% of patients with arteriogenic impotence reporting satisfactory results and improved spontaneous erections.

The device was generally well-received, with over 80% of users rating their satisfaction with erection quality and ability to perform intercourse above 5 on a scale of 1 to 10, although some adverse effects like blocked ejaculation and bruising were reported.

External erection devices, such as vacuum constriction devices, have become increasingly popular as a noninvasive and drug-free option for managing erectile dysfunction, especially as societal stigma decreases.

These devices are effective in providing erections and have been associated with high patient satisfaction, making them a valuable alternative for individuals who may not respond to or prefer not to use medications like sildenafil citrate.

In a 12-month study, an external vacuum device successfully produced erections sufficient for intercourse in 87% of men with erectile dysfunction, indicating its high efficacy as a treatment option.

The use of the device not only improved sexual functioning for men and their partners but also led to a reduction in psychiatric symptoms for the men, highlighting its positive psychosocial effects.

In a study of 29 men using external vacuum devices for 6 months, there were significant improvements in erectile quality, sexual satisfaction, and overall psychosocial well-being, indicating the device's effectiveness in treating erectile dysfunction.

The vacuum device successfully produced erections in 89% of participants, demonstrating its safety and high acceptance among users, with only a 19% dropout rate mainly due to minor side effects like bruising.

Mirodenafil significantly improved erectile function compared to placebo, with a notable increase in the International Index of Erectile Function (IIEF) erectile function domain score after 12 weeks of treatment in a meta-analysis of 374 participants from three randomized controlled trials.

The treatment was well-tolerated, with common side effects including flushing and headache, but these were relatively mild compared to the benefits observed.

The Osbon ErecAid Vacuum Therapy System significantly improved erectile function in 70 patients aged 25-66 who did not respond to PDE-5 inhibitors, with IIEF-5 scores increasing from 10.2 to 13.3 after 3 months of treatment.

The therapy demonstrated a 77.1% effectiveness rate, with over 64% of both patients and their partners reporting increased sexual satisfaction, indicating its potential as a viable treatment option for erectile dysfunction.

In a study of 20 patients with impotence, the Correctaid external erection assistance device was found to be a useful non-invasive treatment option, particularly for motivated individuals and their partners.

After 14 months of follow-up, only 4 patients continued to use the device regularly for satisfactory intercourse, while another 4 used it occasionally, indicating variable long-term adherence and effectiveness.

The new programmable electronic vacuum erection devices, specifically the Vacuum Plus Tratamiento (VPT), have shown efficacy in treating and preventing erectile dysfunction caused by early fibrosis in the penile vascular system, as demonstrated in a study of 20 patients.

These devices work by using low negative pressures to dilate the arterial vascular system of the corpus cavernosum, leading to satisfactory results in achieving passive erections.
