Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels. Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.

Sometimes a combination of physical and psychological issues causes erectile dysfunction. Let me tell you some more causes - Common causes of erectile dysfunction (ED) can include factors like physical health issues (such as heart disease, diabetes, obesity), psychological factors (like stress, anxiety, depression), hormonal imbalances, smoking, alcohol or substance abuse, certain medications, and relationship problems.

The best way to prevent erectile dysfunction is to make healthy lifestyle choices and to manage any existing health conditions. It's important to consult a healthcare professional if you or someone you know is experiencing ED to determine the specific cause and appropriate treatment.
