ED Shockwave Therapy Machine FAQ: Experts Answer Your Common Questions

Product Basics and Core Information

Our WL02 portable ED shockwave therapy machine mainly relies on low-energy extracorporeal shockwave to solve ED problems. It will work in several ways: First, use gentle mechanical stimulation to release substances that can relax blood vessels and help the cavernosum to provide more blood; second, activate related cells and promote new angiogenesis, and improve long-term blood supply like building a “replacement blood vessel”; third, loosen the tissues surrounding the penis and repair damaged nerves, such as solving nerve problems caused by postoperative adhesions or diabetes; in addition, it can also remove tiny blood clots in the blood vessels through the energy of bubble rupture and optimize the tissue environment. Overall, it is not a temporary relief of symptoms, but starts with the fundamental causes of ED, such as improving blood flow and repairing nerves, to help patients recover their natural erections.

Compared to standard devices, the WL02’s core advantages are:
① Portability (5.7 x 6.9 x 1.7 inches, weighing only 1.9 kg, compared to larger and heavier devices)
② Equipped with a specialized ED treatment head (standard devices often use general-purpose massage heads)
③ Wide adjustment range for energy (25-105 mJ) and frequency (1-16 Hz) (standard devices have fixed or narrow adjustment ranges)
④ Built-in cooling fan (standard devices are prone to overheating and shutting down).

This device is portable and can be used at home. It differs from larger hospital devices in the following ways:
① Size and weight: It’s only 1.9 kg, palm-sized, while hospital devices require fixed placement.
② Energy intensity: It uses low energy (25-105 mJ) and is suitable for long-term home rehabilitation. Hospital devices use higher energy (mostly used for critical care or surgical assistance).
③ Difficulty of operation: Adjustable with one click, while hospital devices require specialized personnel for operation.

Clinical data supports this, showing that over 70% of patients achieve natural erections after a 3-6 month treatment course, with an average 25% increase in penile blood flow. Our device has passed CE, FCC, FDA, and ISO certifications, complying with international medical device safety standards. Buy with confidence.

Our machine supports AC 110V/220V, 50Hz/60Hz. No transformer is required. We will deliver the appropriate power plug to the address you provide.

Applicable People and Contraindications

Our device, specifically developed for ED, is suitable for six types of ED patients:
① Mild vascular ED (IIEF-5 score 12-16, PSV 25-29 cm/s, associated with mild hypertension/hyperlipidemia);
② Moderate vascular ED (IIEF-5 score 8-11, PSV 20-24 cm/s, with atherosclerotic plaques);
③ Adjunctive treatment for severe vascular ED (IIEF-5 score <8, PSV <20 cm/s, used as a pre-surgery transition or post-surgery recovery);
④ Mixed vascular and psychological ED (erectile failure caused by vascular problems, accompanied by anxiety);
⑤ Diabetic ED (diabetes-induced endothelial damage and neuropathy);
⑥ Postoperative neurogenic ED (3-6 months after radical prostatectomy, with incomplete nerve severance).

The following individuals are prohibited from using this device to avoid health risks:
① Patients with heart disease, implanted pacemakers, or uncontrolled hypertension;
② Patients with acute inflammation (such as acute prostatitis or urethritis), deep vein thrombosis, goiter, acute asthma attacks, or cancer;
③ Patients with ruptured blood vessels, bleeding wounds, skin inflammation, or edema in the penis;
④ Patients with plastic implants or metal foreign bodies (including metal teeth) in the penis;
⑤ Patients with immune system abnormalities, those who are unresponsive to heat and numbness, or those with coagulation disorders (or those taking anticoagulants);
⑥ Children (whose reproductive system is not fully developed).

Elderly patients: ① Confirm there are no contraindications before use (e.g., no serious heart disease); ② Start with the lowest energy (25 mJ) for the first time and adjust according to tolerance; ③ Stop treatment immediately if dizziness or palpitations occur during treatment.

For patients with underlying medical conditions: Hypertension patients should first control their blood pressure (<160/100 mmHg) before use. Diabetic patients are recommended to use the “Diabetes ED Special Mode” (25 mJ energy, 6-8 Hz frequency). Treatment focuses on the dorsal penile nerve area to reduce nerve stimulation. Monitor blood sugar levels simultaneously and discontinue treatment if blood sugar levels are too high (>11.1 mmol/L).

No. This device is specifically designed for ED. The treatment tip, energy parameters, and mechanism of action are all targeted at the penile blood vessels/nerves. It cannot affect prostate tissue and cannot relieve symptoms of prostatitis, such as inflammation and abnormal urination. Prostatitis requires specialized prostate therapy equipment.

Usage and Experience

It’s simple to operate and supports independent home use. The key steps are as follows: ① Select the treatment head and install it clockwise onto the handle; ② Plug the handle into the main unit’s OUT port and connect the power cord; ③ Press the handle switch to start and then press it to stop; ④ Adjust the energy (25-105mJ) and frequency (1-16Hz) according to your condition.

Note: The energy and frequency settings for each mode must be adjusted based on your condition.

A single treatment lasts 20-50 minutes (mild treatment: 20-30 minutes, severe treatment: 40-50 minutes). There is no noticeable pain during the treatment. Most people only experience a slight soreness and swelling in the penis (similar to the tightness after a massage). Any stinging is usually due to excessive energy levels and can be relieved by lowering the intensity. Mild local soreness or bruising after the treatment is normal and will resolve on its own within 72 hours. No special treatment is required.

Coupling gel is required (to enhance shock wave transmission and prevent energy loss). This is purchased separately (not included in the package). Medical-grade ultrasound coupling gel can be purchased at pharmacies or online platforms. Choose one that is non-irritating and easy to clean.

Three things are necessary before treatment: ① Clean the perineal and penile skin; ② Apply coupling gel (needed to be prepared, as it is not included in the package) to enhance the efficiency of shock wave transmission; ③ Lie supine, fully expose the penis and perineum, and locate the treatment area (bilateral crus of the penis and the middle third of the corpora cavernosa).

During treatment, the penis should be semi-erect and moderately engorged. Reasons: ① When semi-erect, the corpus cavernosum tissue is plump, clearly exposing blood vessels and treatment targets, allowing for more precise shockwave energy. ② When completely flaccid, the tissue is relaxed, making it more susceptible to irritation of surrounding tissues. When fully erect, the corpus cavernosum pressure is high, increasing discomfort and potentially impairing energy transmission. In some cases, a penis pump can be used to assist in achieving a semi-erect state.

Set a frequency and energy level that suits your individual circumstances:

①Mild Vascular Erectile Dysfunction (ED): Energy 25 mJ, Frequency 8-10 Hz, 1500 shocks per session (20-30 minutes);
②Moderate Vascular Erectile Dysfunction (ED): Energy 20-25 mJ, Frequency 10-12 Hz, 2000 shocks per session (30-40 minutes);
③Assisted Severe Vascular Erectile Dysfunction (ED): Energy 25-30 mJ, Frequency 12 Hz, 2500 shocks per session (40-50 minutes);
④Mixed Erectile Dysfunction (ED): Energy 25 mJ (adjustable), Frequency 10 Hz, 25-35 minutes per session;
⑤Diabetic Erectile Dysfunction (ED): Energy 25 mJ (adjustable), Frequency 6-8 Hz, 30 minutes per session;
liuPostoperative Neurological Erectile Dysfunction (ED): Energy 25 mJ (adjustable), Frequency 5 Hz, 20-25 minutes per session.

Avoid sexual intercourse for 48 hours during treatment (to prevent congestion of the corpus cavernosum and affect efficacy evaluation). Precautions: ① Avoid prolonged sitting (<4 hours per day) and strenuous exercise (such as squats and long-distance running); ② Avoid excessive alcohol consumption (<20g of alcohol per day) and smoking; ③ Maintain a regular sleep schedule (sleep 7-8 hours per day) and avoid staying up late (which can affect vascular repair).

The energy parameters are adjustable (25-105 mJ energy + 1-16 Hz frequency). To ensure appropriateness: ① Select a preset mode based on ED type (e.g., 25 mJ for mild ED, 30 mJ for severe ED); ② Start with the lowest compatible energy for the first treatment (e.g., 25 mJ for diabetic ED). If there is no discomfort, you can adjust the energy settings slightly (by 5 mJ each time); ③ Aim for “no noticeable pain, only slight soreness and swelling” rather than blindly pursuing high energy settings.

Treatment Effect and Cycle

Results vary from person to person, but generally: ① About 1 month: Approximately 70% of patients experience improvement in morning erection frequency and firmness (preliminary assessment can be made using the IIEF-5 score); ② 3-6 months: Angiogenesis reaches its peak, with an average 25% increase in penile blood flow. 80% of patients achieve complete nerve repair, and most achieve spontaneous erections.

The treatment course varies depending on the type of ED, as follows:

①Mild vascular ED: 6 sessions (once per week);
②Moderate vascular ED: 8 sessions (twice per week for the first 4 weeks, then once per week thereafter);
③Severe vascular ED with support: 12 sessions (twice per week for the first 6 weeks, then once per week for the next 6 weeks);
④Mixed ED: 8 shockwave sessions + 4 psychological counseling sessions (one to two times per week);
⑤Diabetic ED: 10-12 sessions (once per week);
⑥Postoperative neurological ED: 10 sessions (starting three months after surgery, once per week).

After completing a full course of treatment, the effects typically last for more than six months. This duration can be extended by maintaining a healthy lifestyle (such as quitting smoking, controlling blood pressure and blood sugar, and maintaining a regular sleep and rest schedule). Relapses are often related to poor control of underlying medical conditions (such as rebound blood sugar in diabetes) or unhealthy lifestyle habits (such as prolonged sitting and excessive drinking). Regular follow-up checkups after treatment are recommended, and consolidation therapy is recommended if necessary.

If you stop treatment midway before completing the full course, the improved vascular and nerve function may gradually weaken due to incomplete repair, and the erectile effect may decline. However, it will not completely disappear. When you restart treatment later, you can shorten the initial course based on the duration of the discontinuation (e.g., if you stop for 2-4 weeks, you can resume with the third treatment). This adjustment will be based on your individual situation.

Device Maintenance and After-Sales

The handle requires regular cleaning and component inspection. We recommend maintenance every 10 uses. The steps are as follows: ① Remove the treatment tip and use a tool to loosen the screws on both sides of the handle (do not completely remove it). ② Remove the black rubber ring, metal plate, spring, and other components and wipe them clean with a clean cloth. ③ If the spring is deformed, replace it (a spare spring is included in the package). ④ Reinstall it in the following order: “small end of spring facing down → black rubber ring → metal plate (concave side facing down).” Ensure the notches on the components align with the screws in a cross shape and tighten the screws.

The treatment heads need to be replaced regularly: ① Professional ED treatment head (flat head/cylindrical head): Under normal use, replace every 6-12 months. If surface wear, loose threads, or significantly reduced energy conduction occur, they should be replaced promptly. ② Relaxation and repair head: There is no fixed replacement cycle. After cleaning, the treatment head can be used for a long time. After each use, wipe the treatment head with a clean, damp cloth, let it dry, and then store it.

Long-term storage requires three conditions: ① Ambient temperature -10°C-55°C, relative humidity ≤85%, atmospheric pressure 500HPA-1060HPA; ② The machine and accessories must be packed in their original packaging and stored in a cool, dry, well-ventilated room free of corrosive gases; ③ Before storage, clean the handle and working head, disconnect the power cord, and ensure that all components are free of damage.

Our machines come with a one-year warranty. During this period, we offer free repair or replacement for non-human damage (such as circuit failure or cooling fan failure). If a malfunction occurs, please contact customer service with a description of the problem and proof of purchase. Customer service will assist in resolving the issue.

We support returns and exchanges without reason within 30 days after receiving the goods (must meet the following conditions: ① the machine is not used, not damaged, and has complete accessories; ② the original packaging is intact and does not affect secondary sales); if it cannot be used due to quality problems, you can apply for a return or exchange during the warranty period.

Safety and Side Effects

Common side effects: ① Mild localized soreness and swelling of the penis (dissipates within 1-2 days after treatment); ② Minor subcutaneous ecchymosis (<1 cm², heals spontaneously within 72 hours). Management: No special treatment is required; avoid pressing on the ecchymosis. Apply a cold compress (within 12 hours of treatment) to relieve the soreness and swelling. If the ecchymosis is >2 cm², pause the treatment once and adjust the energy level to a lower level the next time.

No. The device’s energy level (25-105 mJ) is far below the “penile tissue damage threshold” (150 mJ). The energy level is adjustable and certified for safety. Long-term, regular use (up to two full courses per year) targets only the corpus cavernosum vessels/nerves and does not damage the skin, urethra, or other tissues.

If discomfort persists for >48 hours (e.g., pain not relieved, swelling >10% of penis circumference), ① immediately suspend treatment; ② apply ice packs (15 minutes each time, 3 times a day); ③ contact customer service to describe your symptoms, or consult a urologist to rule out other issues (e.g., local infection). Do not self-medicate.

Comparison and Combination Therapy

Advantages: ① Root cause repair: Medications only temporarily dilate blood vessels (ineffective upon discontinuation), while the device repairs blood vessels/nerves (with long-lasting effects); ② No side effects: Medications may cause headaches and flushing, while the device only causes mild soreness and swelling; ③ High privacy: The device can be used at home, eliminating the need for frequent medication purchases. Combination therapy is possible (with doctor’s advice): For patients with severe ED, medication can be used to alleviate symptoms for the first two weeks, while concurrently using a device. After two weeks, medication should be gradually reduced to avoid drug dependence.

Advantages: ① vs. medications: No side effects (medications may cause headaches and visual disturbances), no drug dependency, and no impact on liver and kidney function; ② vs. injections: Non-invasive (injections require a needle and carry the risk of infection) and painless; ③ vs. surgery: Non-invasive (surgery carries the risk of bleeding and infection), no recovery period required, and suitable for patients who prefer not to undergo surgery.

① Severe ED: They cannot replace surgery (such as prosthesis implantation), but can serve as a “preoperative aid” (improving local blood flow and facilitating surgical preparation) or “postoperative rehabilitation” (promoting neurovascular repair and shortening recovery time).
② Peyronie’s disease: Different people have different situations. You need to ask your doctor whether your condition is suitable for low-intensity shock wave therapy to determine whether the equipment is effective for the disease.

Yes. Auxiliary measures: ① Lifestyle adjustment: low-fat and low-sugar diet (>500g of vegetables per day), quitting smoking and limiting alcohol, and regular work and rest; ② Rehabilitation training: Kegel exercises (3 sets per day, 10 repetitions per set, contracting the pelvic floor muscles for 5 seconds and then relaxing) to improve blood circulation in the penis; ③ Psychological adjustment: If you feel anxious, you can do deep breathing exercises (twice a day, 10 minutes each time), or cooperate with psychological counseling.

Other Frequently Asked Questions

Under normal use, the device has a lifespan of 3-5 years (depending on the durability of the core components). Daily maintenance: ① Disconnect the power cord after each use and wipe the main unit surface clean. ② After extended periods of non-use (>1 month): Clean and return to the original packaging. Store in a cool, dry place (temperature -10°C-55°C, humidity ≤85%). ③ Avoid drops and water intrusion (the main unit has a low water resistance rating, and water intrusion can damage the circuitry).

Privacy is guaranteed in two ways: ① Concealed appearance: The device looks like a regular home deep massager and does not have any “ED treatment” related labels, making it difficult for others to identify its purpose. ② No risk of data leakage: The device does not have internet connectivity and does not collect personal information or treatment data, so there is no need to worry about data encryption or leakage.
