What causes difficulty in erection?

Erection difficulties may be caused by psychological stress, vascular disease, hormone imbalance, nerve damage, drug side effects, etc. Common causes of erectile dysfunction ED include psychological factors such as anxiety and depression, chronic diseases such as diabetes, low testosterone levels, neurological problems such as spinal cord injury, and the effects of medications such as antidepressants.

1. Psychological factors:

Chronic anxiety, depression, or partner tension can inhibit the conduction of sexual arousal. Psychogenic ED accounts for more than 40% of cases, manifesting as sudden erectile dysfunction with normal morning erections. Cognitive behavioral therapy and psychological counseling with partners can improve symptoms. In severe cases, combined drug treatment is required.

2. Vascular disease:

Atherosclerosis or high blood pressure can cause insufficient blood flow to the penis. The chance of ED in diabetic patients is three times higher than that of ordinary people, which is closely related to vascular endothelial damage. Controlling blood sugar and blood pressure and taking phosphodiesterase 5 inhibitors can improve blood flow. Patients with severe vascular stenosis require surgical reconstruction.

3. Hormone abnormalities:

Testosterone levels below 300ng/dl can significantly affect erectile function. The decline in hormones during andropause may be accompanied by a loss of libido and feelings of fatigue. Hormone replacement therapy requires monitoring of prostate-specific antigen to avoid inducing prostate disease.

4. Nerve damage:

Diseases such as spinal cord injury and multiple sclerosis can block the erectile reflex arc. Pelvic surgery such as radical resection for rectal cancer may damage the cavernous nerves. Vacuum devices and penile implants are common solutions, but surgical indications need to be evaluated.

5. Drug effects:

Antihypertensive drugs such as beta-blockers and antidepressants such as SSRIs may interfere with erections. Statin lipid-lowering drugs may also cause ED. It is recommended to consult a doctor to adjust the medication plan to avoid other health risks caused by stopping the medication on your own.

Improving erectile function requires comprehensive intervention: maintain 150 minutes of aerobic exercise per week, such as brisk walking and swimming, and enhance cardiovascular function； Consume more arginine-rich walnuts, salmon and other foods to promote nitric oxide synthesis ； Avoid smoking, drinking and other behaviors that damage blood vessels ； Check blood sugar and blood lipid indicators regularly. Partners should avoid blaming and complaining and participate in the treatment process together. If symptoms persist for more than 3 months, it is recommended to go to the men's department for professional examinations such as nighttime erection monitoring and penile blood flow ultrasound.
