How to Increase Erect Penile Length
For many men, penis size—especially erect length—is a major concern. Whether for confidence, aesthetics, or intimate performance, many men wonder if they can increase erect length naturally or surgically.
In this article, we’ll explore what determines erect length, what (if anything) can change it, and the most effective methods for enhancement.
What Determines Erect Length?

Erect length is primarily determined by genetics, hormones, and blood flow. Here are the key contributors:
- Genetics – Just like height, hair color, and facial features, penis size is largely inherited.
- Hormonal Development – Testosterone and other androgens influence penile growth during puberty. If hormone levels were low during puberty, the penis may not have reached its full genetic potential.
- Erectile Tissue & Blood Flow – The corpora cavernosa (two cylindrical chambers inside the penis) expand when filled with blood during an erection. The maximum capacity of these chambers determines erect length.
- Ligament & Skin Elasticity – While the suspensory ligament affects flaccid length, it does not change how much erectile tissue fills with blood when erect.
Can You Naturally Increase Erect Length?
The short answer: no, there is no proven, reliable way to permanently increase erect length without surgery—and even surgery is limited to flaccid length changes.
However, certain non-surgical methods can maximize existing erect length by improving erection quality and function.
Ways to Maximize Erect Length
1. Improve Erectile Function & Blood Flow

Since erect length is limited by blood flow to the erectile chambers, anything that enhances circulation can help achieve full size:
- Pelvic floor exercises (Kegels) to strengthen erection quality.
- A heart-healthy diet rich in nitric oxide–boosting foods (beets, leafy greens, dark chocolate).
- Managing conditions like high blood pressure or diabetes, which can restrict blood flow.
2. Optimize Testosterone Levels
If testosterone is low, medical treatment (like hormone therapy) may help improve erectile function and firmness, making the penis appear longer at full erection.
3. Reduce Fat in the Pubic Area (Lose Weight)

If excess fat accumulates around the base of the penis, it can bury part of the shaft, making it appear shorter. Losing weight can expose more of the natural length.
4. Medical-Grade Penis Extenders (Traction Devices)
- Extenders have been studied for their ability to increase flaccid length with long-term use.
- Erect length gains are less certain, though some studies suggest a modest increase (1-2 cm) over months of consistent use.
Warning: Avoid Jelqing

Jelqing—a stretching technique often promoted online—is extremely dangerous and has no proven benefits.
Medical professionals strongly discourage jelqing due to the risk of:
- Scar tissue formation, leading to permanent curvature (Peyronie’s disease).
- Nerve damage and reduced sensitivity.
- Weakened erections or erectile dysfunction (ED) due to vascular trauma.
Bottom line: Jelqing is not safe or effective and should be avoided.
Surgical Methods: What Can (and Can’t) Be Done?
While surgery can increase flaccid length, there is currently no surgical procedure that increases erect length because surgery does not create new erectile tissue.
What Surgery Can Achieve

1. Penile Repositioning
- Rejuvall’s proprietary penile repositioning technology allows more of the internal penis to extend outward, increasing flaccid length.
- Though many patients have reported an increase in erect length, there is no guarantee that penile repositioning increases erect length because the amount of erectile tissue remains the same.
2. Fat Grafting or Dermal Fillers (For Girth, Not Length)
These increase penile girth but do not impact erect length.
3. Penile Implants (For ED Treatment)
- Used primarily to restore function for men with severe erectile dysfunction.
- Some implant types may increase perceived erect length, but they do not create new erectile tissue.
Rejuvall's MAXL® Non-Surgical Lengthening Program
For men seeking to enhance their erect length without undergoing surgery, Rejuvall offers the innovative MAXL® Non-Surgical Penile Lengthening Program.
Developed by renowned urologists Dr. Steven L. Morganstern and Dr. Kenneth J. Carney, this program utilizes a groundbreaking approach to achieve permanent length gains.

How It Works
The MAXL® program employs a combination of treatments designed to induce physiologic hyperplasia—the natural proliferation of new penile tissue.
This approach makes permanent increases in length possible, including improvements in erect length for many patients.
The treatment involves:
Daily Use of a Penile Traction Device
Patients are guided to use a clinically approved traction device for approximately 37 minutes in the morning and 37 minutes in the evening over a 90-day period.
This gradual stretching process encourages tissue expansion and new cell growth.
Vacuum Erection Device (VED) Therapy
A medical-grade vacuum erection device is incorporated into the program to enhance penile blood flow and stimulate the expansion of erectile chambers.
This improves oxygenation and elasticity, aiding in tissue proliferation.
Blood Flow Therapy – External Counterpulsation (ECP)
ECP therapy is used to enhance circulation and improve vascular function in the penis.
By optimizing oxygen and nutrient delivery, this therapy supports tissue growth and helps maximize erectile function.
Nutraceutical Support
A customized 90-day supply of nutraceuticals is provided to support tissue regeneration and accelerate cellular proliferation.
These supplements optimize hormonal balance and nitric oxide levels for improved blood flow and healing.

Proven Results
Rejuvall’s extensive research and development have demonstrated the effectiveness of the MAXL® program:
- Patient Outcomes: Over 500 men have successfully achieved non-surgical penile lengthening through the MAXL® program.
- Permanent Gains: The new tissue generated through physiologic hyperplasia is permanent, ensuring that length increases are maintained even after the completion of the program.
- Erect Length Enhancement: Many patients have reported noticeable increases in erect length as a result of the program, attributing these gains to the creation of new erectile tissue through the induced hyperplasia process.
Safety & Commitment
The MAXL® program is designed to be safe and effective, with no need for cutting, stitches, or anesthesia.
Patients are encouraged to commit to the daily regimen for the full 90 days to achieve optimal results. The process is user-friendly, allowing individuals to incorporate the therapy into their daily routines conveniently.

Can Science Ever Increase Erect Length?

At present, there is no known way to grow new erectile tissue. However, future tissue engineering and stem cell research may open the door to potential solutions.
Experimental techniques such as shockwave therapy and platelet-rich plasma (PRP) injections are being explored for erectile function enhancement, but not for structural penile lengthening.
Final Verdict: What’s the Best Approach?
- If you want to maximize erect length, focus on optimizing blood flow, hormone levels, and overall penile health.
- If you want to increase flaccid length, surgical penile repositioning is an option.
- For noticeable changes in appearance, girth enhancement procedures may offer more dramatic results than length-focused methods.
