Erectile dysfunction affects many men, especially after episodes of spinal cord injury or pelvic surgery. In these cases, men lose natural erections due to lack of sensitivity below the waist and pills like the famous Viagra do not work in this scenario.
So science is looking for ways to restore nerve pathways to help these patients and one of the solutions comes from Brazil. A device called “Electronic Viagra” has shown very promising results in its first tests, reversing erectile dysfunction in 90% of patients.

Current treatments use implants that maintain permanent artificial rigidity, with surgically placed internal supports, and which result in virtually no sexual sensitivity. What the Brazilian device tested since 2023 offers is to stimulate blood flow to the penis through electrical stimuli, a proposal more similar to the natural erection process.
The method involves implanting a neurostimulator device under the skin in the lower abdomen. Wires connect it to the area near the prostate and pubic bone and, using a remote control, it is possible to turn on the electrical stimuli and adapt them to the body of each patient.
CaverSTIM: electronic viagra
The official name of the device is CaverSTIM. The first surgical procedure to implant it took place in October 2023 and 10 patients, all aged under 34, have been operated on since then, the vast majority with good erection results under regular clinical monitoring.
Reports also indicated progress in other body functions due to the stimuli that strengthened the neural region and the sensitivity of the region. Even with the neuromodulator turned off, penile sensitivity increased after surgery.
“The patients are still being monitored, but the first results are very good. The improvement in urological and evacuation functions of the men who participated in the tests is also surprising,” emphasizes urologist Sidney Garcia, one of the coordinators of the current study at the Mário Covas Hospital, in Santo André (SP).

A pelvic stimulator?
Despite its nickname of electronic Viagra, the device works in practice much more like a pacemaker, thanks to its electrodes and its implantation under the skin. Nine of the ten patients regained their power and sensitivity approximately two months after the procedure and without the need for medications or injections.
At the end of the period, some patients did not need stimulation of the device to regain natural erections thanks to the reconditioning of the nerve pathways. As a result, the system now has two clinical uses, both temporary and permanent, for people with spinal cord injuries, where nerve pathways remain interrupted.
In these cases, even with stimulation, maintaining an erection during intercourse may fail.
