Male Erectile Dysfunction (ED) is a common condition where a man has difficulty achieving or maintaining an erection suitable for sexual activity. It can affect men of all ages but is more prevalent in older adults. Various factors contribute to ED, including physical health issues, psychological factors, and lifestyle choices. Common physical causes include diabetes, heart disease, and obesity, while psychological factors may involve stress, anxiety, or depression. Lifestyle choices such as smoking, excessive alcohol consumption, and lack of exercise can also play a role. Treatment options are available and can include medication, therapy, or lifestyle changes.
