Key terms (glossary)

- The persistent difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity.
- Impotence medication
- Drugs used to improve erectile function, commonly by enhancing blood flow to penile tissue.
- PDE5 inhibitors
- A class of medications (e.g., sildenafil, tadalafil) that relax blood vessels to support erections.
- Sildenafil
- A short-acting PDE5 inhibitor often taken on demand.
- Tadalafil
- A longer-acting PDE5 inhibitor that can be taken daily or on demand.
- Vardenafil
- A PDE5 inhibitor similar to sildenafil with a slightly different onset profile.
- Avanafil
- A newer PDE5 inhibitor with faster onset in some users.
- Nitric oxide
- A signaling molecule that triggers blood vessel relaxation in erectile tissue.
- Vasodilation
- Widening of blood vessels, increasing blood flow.
- Libido
- Sexual desire; distinct from erectile ability.
- Hypogonadism
- A condition of low testosterone that may contribute to ED.
- Psychogenic ED
- Erectile dysfunction primarily related to psychological factors such as stress or anxiety.
- Organic ED
- Erectile dysfunction linked to physical causes like vascular disease or diabetes.
- Contraindications
- Situations where a medication should not be used due to risk.

Clear explanation
What causes erectile dysfunction?
ED is multifactorial. Common causes include reduced blood flow from cardiovascular disease, nerve damage from diabetes, hormonal imbalances, medication side effects, and psychological factors such as anxiety or depression. Because impotence medication primarily targets blood flow, identifying the underlying cause helps determine whether medication alone is appropriate or if additional treatment is needed.
How impotence medication works
Most impotence medications are PDE5 inhibitors. They enhance the natural erectile response to sexual stimulation by preserving nitric oxide signaling, leading to vasodilation and increased penile blood flow. These drugs do not create desire and usually require sexual arousal to be effective.
Common manifestations and expectations
When effective, impotence medication can improve erection firmness and duration. Response varies based on dose, timing, food intake, and individual health. Side effects may include headache, flushing, nasal congestion, or indigestion; serious effects are uncommon but require prompt medical attention.
Diagnosis before treatment
Diagnosis typically includes a medical and sexual history, medication review, physical examination, and sometimes blood tests (e.g., glucose, lipids, testosterone). This step ensures that impotence medication is safe and that contributing conditions are addressed.
Approaches beyond medication
Lifestyle changes (exercise, weight management, smoking cessation), psychological support, vacuum devices, or hormonal therapy may complement or, in some cases, replace impotence medication. A combined approach often yields the best outcomes.
Reader checklist
What you can do
- Discuss symptoms openly with a healthcare professional.

- Seek credible education in our general health resources section.
What to avoid
- Using impotence medication without medical guidance.
- Combining PDE5 inhibitors with nitrates or recreational drugs.
- Expecting immediate results without sexual stimulation.
- Ignoring side effects or worsening symptoms.
When to see a doctor urgently
- Chest pain, severe dizziness, or fainting after use.
- An erection lasting more than four hours (priapism).
- Sudden vision or hearing loss.
- Signs of an allergic reaction (swelling, rash, difficulty breathing).
| Term | In simple words | Why it matters |
|---|---|---|
| PDE5 inhibitor | Medicine that helps blood flow | Main mechanism behind most ED drugs |
| Nitric oxide | Natural signal for vessel relaxation | Essential for normal erections |
| Contraindication | Reason not to use a drug | Prevents dangerous complications |
| Psychogenic ED | ED linked to stress or emotions | May need counseling in addition to medication |
| Hypogonadism | Low testosterone | Can reduce response to ED medication |
Specialist comment (generalized): “For many patients, impotence medication is effective and safe when properly prescribed. The best results come from matching the medication to the individual’s health profile and addressing lifestyle and psychological factors at the same time.”
