Erectile dysfunction (ED) is the inability to get or keep an erection during sexual activity. It occurs when there is a problem with blood flow to the penis. ED can be caused by physical problems, psychological issues, or a combination of both.

Erectile dysfunction (ED) is a sexual disorder that affects a man's ability to develop or maintain an erection of the penis during sexual performance. ED can have many causes, both physical and psychological. Physical causes include conditions such as diabetes, heart disease, and nerve damage. Psychological causes can include anxiety, stress, and depression. In many cases, ED is the result of a combination of physical and psychological factors.

Erectile dysfunction medications such as Sildenafi and Tadalafil can cause mild or temporary side effects. These include headaches, flushing, indigestion, dizziness, and skin rash. If you experience any of these side effects, you should stop taking the medication and seek medical help immediately. Although erectile dysfunction medications are generally safe, it's important to remember that they are not suitable for everyone. If you have a history of heart disease or stroke, you should not take these medications without first consulting with your doctor.
