Viagra, known by many as the “little blue pill”, has represented a true revolution in the treatment of erectile dysfunction since its introduction to the market. However, despite its fame, many doubts and questions still remain about how it really works, its benefits, and its limits. What is Viagra used for?
Is this medication a solution for everyone, or are there more modern and effective alternatives? In this in‑depth article, we will answer these and other questions with the clarity and scientific rigor that define the approach of Prof. Fabio Castiglione, an internationally renowned Consultant Urologist & Andrologist. At his London clinic, the Erectile Dysfunction Clinic, Prof. Castiglione offers patients the most cutting‑edge solutions, guiding them toward restoring a full and satisfying sex life, often going beyond mere prescription medication.
What Is Viagra Used For? What Is Viagra and How Does It Work?
Viagra is the brand name of the drug whose active ingredient is sildenafil. Belonging to the class of phosphodiesterase type 5 inhibitors (PDE5), sildenafil was initially studied for the treatment of hypertension and angina pectoris. During clinical trials, researchers noticed an “unexpected side effect”: a marked improvement in erectile function among male participants. From there, its course was redefined, making it the first and most famous oral treatment for erectile dysfunction.
Its mechanism of action is primarily vascular. Erection is a complex hemodynamic event that depends on adequate blood flow to the penis. Under normal conditions, sexual stimulation triggers the release of nitric oxide (NO) in penile tissue, which in turn activates an enzyme that produces cyclic guanosine monophosphate (cGMP). cGMP is the key molecule that causes the smooth muscle of the corpora cavernosa (the two sponge‑like columns of penile tissue) to relax, allowing blood to flow in and generate an erection.
PDE5 is another enzyme naturally present in the body, whose job is to break down cGMP, returning the penis to its flaccid state. Erectile dysfunction often involves an imbalance in this process. Sildenafil works by selectively inhibiting the PDE5 enzyme. By blocking this enzyme, Viagra allows cGMP to remain active longer, enhancing and prolonging the vasodilatory effect and promoting a stronger, longer‑lasting blood flow to the penis in response to sexual stimulation. It is crucial to emphasize that Viagra is not an aphrodisiac and does not cause an automatic erection: sexual input (visual, tactile, psychological) is always required to initiate the process.

Main Therapeutic Benefits of Viagra
The primary and most evident benefit of Viagra is the symptomatic treatment of erectile dysfunction of various origins—organic (vascular, neurological), psychogenic, or mixed. Understanding how Viagra works means recognizing its direct impact on a man’s physiological ability to respond to arousal.
It leads to a significant increase in the ability to achieve and maintain an erection firm enough to allow for a satisfying sexual intercourse. For many men who experience the frustration and anxiety associated with erectile difficulty, this represents a radical change. The restored reliability of their erectile response allows them to approach intimacy with greater calm and spontaneity.
Improvement in sexual and psychological quality of life. Erectile dysfunction is not just a physical problem; its psychological repercussions can be devastating. Performance anxiety, lowered self‑esteem, depression, and relationship strain are common consequences. By restoring erectile function, Viagra can break this vicious cycle. The man feels more confident, anxiety decreases, and communication with his partner improves. This recovery affects not only the individual but also the balance and intimacy of the couple.
However, as Prof. Fabio Castiglione always emphasizes, the drug treats the symptom, not necessarily the underlying cause. Therefore, a comprehensive diagnostic approach is essential to identify the root of the problem and define a truly curative therapeutic path, not just a palliative one.
FAQ: Answers to Users’ Frequently Asked Questions
Searching online for information about Viagra can be confusing. Below, Prof. Fabio Castiglione answers with clarity some of the most common questions, based on user searches, to shed light on Viagra and what to realistically expect from its use.
Does Viagra Maintain the Erection Even After Ejaculation?
The answer is: generally no. After ejaculation, the body enters a natural phase known as the “refractory period,” during which it is physiologically difficult, if not impossible, to achieve another erection. Viagra does not eliminate this refractory period, although some studies and anecdotal reports suggest it may shorten it in some men. The drug works by facilitating the blood flow necessary for an erection in the presence of stimulation, but it does not override the physiological mechanisms that regulate the post‑orgasm phase. Therefore, once orgasm is reached, it is normal for the erection to subside.
Does Viagra Make the Penis Bigger?
Absolutely not. Viagra has no effect on the structural size of the penis. It is not a penis‑enlargement drug. Any impression of a “larger” penis comes solely from the fact that the drug allows one to reach the maximal hemodynamic erection possible for that individual. In other words, the penis reaches its full erect size, which may not have been achieved for a long time due to erectile dysfunction. Viagra restores the fullness and rigidity of the erection but does not alter the anatomy or basic dimensions of the penis.
Does Viagra Automatically Cause an Erection?
No, Viagra does not cause a spontaneous or uncontrolled erection. As explained in its mechanism of action, sildenafil only works in response to sexual stimulation. If a man takes a “little blue Viagra pill” and receives no erotic stimulus (mental or physical), nothing will happen. This feature is critical for its safety and acceptability, as it allows for a natural, non‑mechanical sexual experience. We can say that it serves to restore the natural response to arousal.
Does Viagra Help You Last Longer During Intercourse?
Here the issue is more complex. Viagra is not a treatment for premature ejaculation. Its primary purpose is to treat the difficulty of achieving or maintaining an erection. However, some men experience an indirect improvement in duration. This may be due to psychological factors: the confidence of having a reliable erection reduces performance anxiety, which is often a co‑cause of premature ejaculation. Additionally, by maintaining the erection longer, a man may feel less pressured to “finish quickly” for fear of losing it.

Side Effects and Contraindications of Viagra
Like any medication, Viagra is not free from possible side effects and carries important contraindications. Although generally well tolerated, it is essential to be aware of the risks. The most common side effects, usually mild and transient, include: headache, facial flushing, nasal congestion, digestive disturbances, and visual alterations (such as a slightly blue‑tinted vision or increased light sensitivity).
Are There Absolute Contraindications? Who Should Not Take Viagra?
The drug is strictly contraindicated in patients taking nitrate‑based medications (used to treat angina pectoris), because the combination can cause a drastic and potentially fatal drop in blood pressure. It is also not recommended for patients with severe heart or liver problems, with hypotension (low blood pressure), or those who have recently had a stroke or heart attack. That is why consulting a specialist like Prof. Castiglione is not optional but essential. Self‑diagnosis and purchasing through unofficial channels, such as generic “pharmacy online viagra,” entail significant health risks.
How to Take Viagra Correctly
To maximize efficacy and minimize risks, it is crucial to follow medical dosage instructions. Viagra should be taken about 30–60 minutes before the planned sexual activity. Taking it on an empty stomach speeds absorption, while a heavy, fatty meal can delay and reduce its effect.
The dosage, such as the well‑known Viagra Pfizer 100 mg, must be determined by a doctor. One usually starts with an intermediate dose (e.g., 50 mg), then adjusts based on the patient’s response and tolerance. It is important not to exceed the prescribed daily maximum dose (generally 100 mg) and not to take it more than once a day. Variants like Viagra Connect, available without prescription in some countries, have standard dosages and are not suitable for everyone. Medical advice is the only way to ensure safe use.
Therapeutic Alternatives to Viagra Proposed by Prof. Castiglione—“What’s Beyond?”
Modern medicine, and particularly Prof. Castiglione’s approach, aims to offer solutions that do not merely manage the symptom but can regenerate erectile function. At the Erectile Dysfunction Clinic London, advanced, personalized therapies with curative potential are offered.
The most innovative non‑pharmacological options
Low‑intensity shockwave therapy (Shockwave Therapy)
This non‑invasive technology uses acoustic waves to stimulate neo‑angiogenesis, i.e., the formation of new blood vessels in penile tissue. By improving vascularization, it directly addresses the cause of many organically based erectile dysfunctions, with the goal of restoring spontaneous erections without medication.
Pshocks (PRP + P‑Shocks + shockwave)
This is the excellence protocol developed and offered by Prof. Castiglione. It combines the regenerative power of shockwaves with PRP injections (Platelet‑Rich Plasma), a concentrate of growth factors obtained from the patient’s own blood. This synergy aims to repair damaged tissue, improve circulation, and rejuvenate erectile function at the cellular level. It is a cutting‑edge regenerative therapy that addresses the root of the problem.
Next‑generation penile prostheses
For the most severe cases that do not respond to other therapies, prosthetic surgery offers a definitive and highly satisfying solution. Modern hydraulic penile implants are sophisticated devices, fully internal and invisible, that provide an on‑demand erection with a completely natural look and feel for both partners.
Conclusion
We have seen how Viagra serves as an effective tool to temporarily manage the symptoms of erectile dysfunction, restoring the ability to achieve an erection for many men. However, it is not a cure and not suitable for everyone. Its use requires careful medical evaluation to avoid risks and determine whether it is the most appropriate therapeutic strategy.
Today, thanks to specialists like Prof. Fabio Castiglione, the therapeutic horizon has expanded significantly. From regenerative therapies like shockwave and the Pshocks protocol to definitive surgical solutions, there are concrete pathways to address and resolve erectile dysfunction at its root. If you are struggling with this issue, do not trust makeshift solutions.
