Erection refers to the enlargement and hardening of the penis in men. The health of blood and blood vessels is essential for an erection. When sexually aroused, the parasympathetic nervous system is activated, causing the penile arteries to dilate, increasing blood flow. A strong erection occurs when a sufficient amount of blood enters the corpora cavernosa of the penis and the flow is smooth. Healthy men typically experience morning erections, which is a natural physiological response. However, conditions like stroke or heart disease can lead to reduced penile rigidity or erectile dysfunction.

Taking Erectile Dysfunction Medication Without Proper Diagnosis is Risky

According to research by the Korean Urological Association and other bodies, conditions such as hyperlipidemia, diabetes, hypertension, obesity, depression, and prostate diseases can cause erectile problems. Notably, abnormalities in the heart's blood vessels can increase the prevalence of erectile dysfunction by up to 4 times. In such cases, blindly taking erectile dysfunction medication shared by a friend can be dangerous due to sudden vasodilation. Therefore, if you consistently experience poor erections, it is safer to undergo a health check-up before relying on erectile dysfunction drugs.

Various Causes of Erectile Problems

Erection is a complex physiological response involving the coordinated action of the vascular, endocrine, and nervous systems. The causes of erectile dysfunction are diverse and include:

• Vascular problems: Can occur due to atherosclerosis, where blood vessels narrow or harden.
• Psychological issues: Stress or depression can also affect erectile function.
• Male menopause (Andropause): In middle-aged men, severe andropause can lead to decreased erectile function.

When the blood flow to the penis is impaired due to these causes, it can lead to arteriogenic erectile dysfunction. If the penis cannot retain blood once it enters, it is called veno-occlusive erectile dysfunction.

Do I Need a Diagnosis for Erectile Dysfunction?

If erectile dysfunction occurs in more than 50% of sexual encounters and persists for more than 6 months, a medical evaluation is necessary. This evaluation should first assess psychological factors, physical abnormalities, and underlying diseases. Blood tests measuring glucose, cholesterol, various blood lipid levels, and testosterone levels are required. The examination can be tailored based on the patient's condition and the physician's judgment. Problems with the nerves controlling erections can arise not only from vascular diseases but also from central nervous system disorders like Parkinson's disease or peripheral nerve issues such as vitamin deficiencies.

Preventing Underlying Conditions Through Lifestyle Modifications

When erectile problems arise, the first step is to review your lifestyle habits. Consider factors such as age, smoking, alcohol consumption, obesity, hyperlipidemia, diabetes, hypertension, depression, and prostate diseases. In particular, cardiovascular diseases are very serious and require prompt treatment. Smoking is detrimental to vascular health and can damage not only erectile function but also the blood vessels of the heart and brain. Therefore, quitting smoking and reducing alcohol intake are crucial. Erectile dysfunction medication requires a doctor's prescription, and individuals with heart disease must exercise extreme caution.
