Impotence medication: complete glossary, explanation, and checklist

Disclaimer: This article is for educational purposes only and does not replace professional medical advice, diagnosis, or treatment.

Tadalafil

Intracavernosal injection

Clear explanation

1. Causes of erectile dysfunction

Erectile dysfunction is often multifactorial. Common physical causes include reduced blood flow due to atherosclerosis, diabetes-related nerve damage, hormonal imbalances (such as low testosterone), obesity, and side effects of medications. Psychological factors—stress, depression, relationship issues, and performance anxiety—can also contribute. In many cases, ED is an early warning sign of cardiovascular disease.

2. Manifestations and symptoms

The main symptom is difficulty achieving or maintaining an erection firm enough for intercourse. Some men also report reduced sexual desire or premature loss of erection. Symptoms may be occasional or persistent. The pattern—sudden vs. gradual onset—can help differentiate psychological from physical causes.

3. Diagnosis and evaluation

Diagnosis begins with a medical history and physical examination. A clinician may order blood tests (glucose, lipids, testosterone), assess cardiovascular risk, and review current medications. In selected cases, specialized tests such as penile Doppler ultrasound or nocturnal erection testing may be recommended.

4. Treatment approaches and impotence medication options

PDE5 inhibitors (sildenafil, tadalafil, vardenafil, avanafil) are typically first-line impotence medication options. They improve blood flow in response to sexual stimulation. These drugs differ in onset (15–60 minutes) and duration (4–36 hours).

If oral therapy is ineffective or contraindicated, alternatives include alprostadil injections, intraurethral suppositories, vacuum erection devices, hormone therapy (when testosterone deficiency is confirmed), and in some cases, penile implants. Lifestyle modifications—weight loss, smoking cessation, exercise—can significantly improve outcomes.

Specialist comment (generalized)

“Erectile dysfunction is often a marker of overall vascular health. While impotence medication is highly effective for many men, treatment works best when combined with lifestyle improvements and evaluation of cardiovascular risk factors. Patients should view ED therapy as part of comprehensive health care, not just symptom relief.”
