Despite rumors that tadalafil increases size, it does not actually enlarge the penis. It helps achieve an erection without altering penile characteristics. Learn more below!
Many men are curious about the effects of Tadalafil, including whether Tadalafil increases penis size. This myth does not reflect the real benefits of the medication, which should be taken under medical supervision.
Discussions about the effects of this drug have increased interest in Tadalafil. In 2023, over 40 million units were sold in pharmacies—a 38.9% rise compared to 2022—according to the consultancy Close-UP International.
Tadalafil is not always used properly. It is indicated for treating erectile dysfunction, but some people believe the medication can permanently enlarge the penis, among other myths. Read on to discover the real benefits of Tadalafil and avoid problems.
What Is Tadalafil, and What Is It Used For?
Tadalafil is an oral medication for erectile dysfunction developed in the early 2000s. Its main advantage is a long-lasting effect, over 36 hours.
This drug is a potent, selective, and reversible inhibitor of phosphodiesterase 5 (PDE5) that improves blood flow, especially to the penis, facilitating an erection. It works by dilating blood vessels, a process called vasodilation.
Tadalafil is also indicated for treating high blood pressure in the lungs (pulmonary arterial hypertension) and prostate conditions, such as benign prostatic hyperplasia.

So, Does Tadalafil Increase Penis Size?
The answer is no! Tadalafil does not permanently enlarge the penis.
What really happens is that, when you take the medication, blood flow to the penis increases. This allows you to achieve a firmer erection, which can sometimes make the penis seem larger.
This effect is temporary and only happens while the drug is active.
In other words, it might appear that Tadalafil increases size during an erection, but it does not change the organ’s actual dimensions.
How Many Centimeters Does Tadalafil Increase?
Tadalafil does not cause a real increase in penis length. What may happen is a more rigid and longer-lasting erection, which can make the penis look larger compared to when a man cannot achieve a full erection.
Men who experience erectile dysfunction and, therefore, do not achieve a satisfactory erection might think they gained a few centimeters—but that is not true.
For Which Conditions Is Tadalafil Indicated?
Tadalafil is indicated for:
- Erectile dysfunction (trouble achieving an erection);
- Pulmonary arterial hypertension;
- Urinary problems caused by an enlarged prostate.
Use must be monitored by a doctor. People with heart conditions or uncontrolled high blood pressure may, in some cases, take this medication, but always under medical supervision.
What Are the Real Benefits of Tadalafil?
Tadalafil is a medication used to treat erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. Its principal mechanism of action is vasodilation, which can offer several therapeutic benefits, such as:
- Penile vasodilation
- Improvement in sexual performance
- Increased confidence for sexual intercourse
- Slower rate of prostate growth
- Relief of urethral compression
- Improvement of urinary problems caused by an enlarged prostate
- Lung decompression
- Better breathing
It is important to note that the medication’s effects may vary from patient to patient. A medical evaluation is essential for proper monitoring.
On the other hand, there is no scientific evidence that Tadalafil provides any benefits for physical performance or improving bodybuilding results.
Does Tadalafil Increase the Prostate Size?
In fact, Tadalafil helps reduce the size of the prostate.
What Tadalafil does is slow the rate of prostate enlargement in cases of benign prostatic hyperplasia that require attention.
By helping to relax the muscles of the prostate and the bladder, the medication makes it easier for urine to pass, one of the consequences of BPH.
Tadalafil and Sexual Performance: What Is the Connection?
Tadalafil has a strong link to sexual performance because it can provide a higher-quality erection and longer-lasting erection. This is crucial for intercourse, especially penetration.
However, good performance does not depend solely on medication. Emotional control, partnership between both individuals, and managing anxiety are also important for a satisfying sex life.
Is There Any Medication That Increases Penis Size?
No medication actually enlarges the penis. Drugs like Tadalafil and Sildenafil help men achieve a firm, long-lasting erection, but they do not make the penis grow.
Be alert to products claiming to deliver such results, as they are misleading and may harm your health.
Is It Possible to Increase Penis Size?
Some methods aim to increase penis size, recommended for men diagnosed with a condition that reduces or prevents normal penile growth, always under medical supervision. They include:
- Hormonal treatments: indicated for men with hormonal deficiencies, such as low testosterone;
- Mechanical devices: traction therapy or a vacuum pump may have a slight effect, restoring the organ’s length;
- Surgeries: procedures like phalloplasty, which help men with micropenis, and the Egydio Technique for Peyronie’s Disease can increase penis size.
Men who do not have related conditions are not eligible for treatments to increase or restore penis measurements.
Avoid Self-Medication and Consult a Doctor If Needed
Taking medication without medical supervision can be dangerous. Tadalafil should be used carefully, at customized doses, to prevent side effects such as headache, nasal congestion, and dizziness.
Always consult a doctor before using any medication. If you are having sexual health issues, contact urologist Dr. Paulo Egydio for safe and effective care.
Although many people believe that tadalafil increases size, this is not true. The medication improves erection quality, but it does not permanently enlarge the penis. Your sexual health can be regained with professional help.
