Extended protection has value when it adds meaningful coverage beyond the original warranty.
Read source ↗Designed around external contact.
The prostate sits inside the pelvis. PrimeArc III is designed to meet the body externally at the perineal and scrotal regions—without internal insertion.
INTERNAL REFERENCE
Located inside the pelvis.
The prostate sits within the male pelvis, beneath the bladder. It is shown here as an anatomical reference to illustrate the surrounding structures. PrimeArc is engineered to transmit calibrated micro-acoustic energy through the external skin into the underlying tissue to maintain vascular responsiveness.
EXTERNAL REGION
Designed for targeted contact.
The perineum is the external area between the scrotum and anus. PrimeArc's lower contour is designed to align with this region and deliver targeted low-intensity acoustic pressure directly to the underlying perineal tissue.
EXTERNAL REGION
A highly innervated contact area.
The scrotal skin contains a dense network of sensory nerves and micro-vessels. PrimeArc's raised silicone nodes are designed to deliver localized micro-acoustic stimulation across this external surface, engaging neurovascular receptors within the skin and underlying tissues.
PRODUCT GEOMETRY
Two contact zones. One integrated design.
PrimeArc is shaped to engage both the perineal and scrotal regions within a single external wearable structure. Its geometry positions each contact zone to deliver dual-point micro-acoustic therapy, combining targeted perineal contact with scrotal micro-wave delivery in one integrated at-home system.
A response built from signal, relaxation and flow.
Erection is not one event. Neural input, nitric-oxide signaling, smooth-muscle relaxation, blood inflow and reduced venous outflow work together.
SCHEMATIC · PHYSIOLOGY VISUALIZATION
Sensory + psychogenic signals.
Penile afferent input can participate in reflexogenic erection, alongside brain-driven sexual stimuli.
Neural signaling + nitric oxide.
Neural and endothelial nitric oxide contributes to cavernosal smooth-muscle relaxation.
More room for blood.
Relaxed smooth muscle allows greater arterial inflow and expansion of erectile tissue.
Expansion limits outflow.
Expansion compresses venous outflow, helping pressure and firmness rise and remain.
RESEARCH NOTE
These mechanism reviews support the physiology shown here.
Aging can change the response system.
Aging does not automatically cause erectile dysfunction, but vascular and tissue changes can make erectile response less efficient for some men.
Vascular response can decline with age.
With age, blood vessels can become less responsive, making it harder to dilate quickly when blood flow needs to increase.
2025 vascular-aging review ↗
Greater vascular stiffness.
Arteries commonly become stiffer with age, which can make rapid increases in blood inflow harder to achieve.

DUAL Micro-Acoustic TRANSDUCERS. Two physical locations.
PrimeArc III features two calibrated Micro-Acoustic Transducers designed to emit targeted, low-intensity acoustic pressure pulses. This dual-source delivery ensures uniform acoustic energy distribution across the perineal and scrotal target areas for safe, unassisted home application.
Two actuators. Two physical locations.
One actuator sits beneath the raised silicone texture. A second actuator sits inside the lower handle.
Micro-acoustic wave emitter beneath the raised texture.
The upper acoustic transducer is positioned horizontally beneath the raised silicone surface, concentrating calibrated micro-acoustic energy directly at the scrotal zone to maintain local vascular responsiveness.
Perineal micro-acoustic drive in the lower handle.
The lower acoustic transducer is aligned vertically within the handle structure, delivering a second independent stream of targeted acoustic pressure directly to the perineal tissue.
Dual-source micro-acoustic architecture.
PrimeArc III delivers calibrated micro-acoustic energy simultaneously across the scrotal and perineal zones, providing comprehensive dual-point support to complement clinical Li-ESWT.

EXPERT PERSPECTIVE
Expert perspective.
Successful erectile rehabilitation is not defined by medication alone; it depends on maintaining neurovascular responsiveness, appropriate sensory input, and the hemodynamic mechanisms required for erection. Devices like PrimeArc III complement clinical low-intensity shockwave therapy with targeted micro-acoustic energy, providing controlled, non-invasive acoustic stimulation to the external perineal and scrotal regions as a drug-free, at-home adjunct. This allows patients to maintain a more consistent rehabilitation routine between clinic-based treatment sessions.

Frequently asked questions.
Technology, use, privacy and the evidence behind PrimeArc III.
What exactly is PrimeArc III?
PrimeArc III is a wearable male wellness system designed to deliver controlled, targeted stimulation through dual pulse actuators and two external contact zones. Its architecture combines focused stimulation, a dual-ring fit system, and app-based personal control in one private at-home device.
Is PrimeArc III a clinical Li-ESWT device?
No. Clinical Li-ESWT systems generate acoustic pressure or shock waves using specialized medical equipment following strict clinical protocols. PrimeArc III uses dual pulse actuators to deliver targeted stimulation through direct external contact. While both apply physical energy to tissue, they differ fundamentally in how that energy is generated, transmitted, and applied.
Is PrimeArc III just a conventional vibrator?
No. PrimeArc III is not designed as a conventional vibrator. It is a purpose-built male wellness system that uses dual pulse actuators to deliver targeted stimulation across two external contact zones. Penile vibratory stimulation has been studied in clinical and rehabilitation contexts for erectile function. PrimeArc III brings this targeted stimulation concept into a private, app-controlled at-home format.
Why does PrimeArc use dual micro-acoustic transducers?
The dual pulse actuators deliver stimulation across two separate external contact regions. This creates a broader coverage pattern than a single source and allows dynamic stimulation profiles to be distributed throughout the device.
Why are there two rings?
The two rings have different roles. Ring 1 helps position and stabilize PrimeArc during use. Ring 2 is a support ring designed to help maintain and prolong an erection by reducing blood outflow from the penis.
How does vibration relate to erectile response?
Erectile response involves both nervous-system signaling and vascular tissue. Penile vibratory stimulation has been investigated in human research in several areas of male sexual function.
Does PrimeArc treat erectile dysfunction?
PrimeArc III is not intended to replace clinical diagnosis or specialist treatment for erectile dysfunction. It is designed for adjunctive at-home use alongside clinician-directed care, providing targeted stimulation as part of a broader erectile-health routine while professional treatment decisions remain under the direction of a qualified healthcare provider.
Can PrimeArc be used between professional treatment sessions?
Yes. PrimeArc III is designed for private, repeatable at-home use as an adjunct to clinician-directed care between professional sessions. It provides controlled stimulation at home alongside specialist treatment and can be incorporated into a broader erectile-health routine without replacing established clinical protocols.
How do I control PrimeArc?
PrimeArc can be controlled through the OGO App. The app provides access to multiple stimulation patterns and intensity control so the experience can be adjusted to personal preference.
Do I need to pair PrimeArc with my phone?
No traditional Bluetooth pairing process is required. Turn on PrimeArc, enable Bluetooth on your phone and open the OGO App. The app detects compatible PrimeArc devices within range and sends control commands directly to the device.
How should PrimeArc be cleaned?
Follow the care instructions supplied with PrimeArc III. Allow the device to dry completely before storage or charging, avoid harsh solvents or abrasive cleaners, and do not soak or submerge the device.
When does my warranty begin?
PrimeArc III includes a 1-year limited warranty that activates automatically on the calendar day after the eligible order is marked successfully delivered (T+1). No manual activation is required. If OGO Care is purchased and linked to the device, eligible coverage is extended to 2 years total from that same coverage start date.
Is my use of PrimeArc private?
PrimeArc is designed around private ownership and at-home use. OGO does not require conventional Bluetooth pairing between the device and phone. Any account, order and app-data practices are governed by OGO's published Privacy Policy.
