Erectile dysfunction (ED) occurs when a man struggles to achieve or maintain an erection firm enough for sexual activity. It's often due to insufficient blood flow to the penis. Several factors can contribute to ED, including physical conditions like cardiovascular issues, diabetes, and high blood pressure, psychological factors such as stress and depression, lifestyle choices like smoking and excessive alcohol consumption, hormonal imbalances, neurological conditions, age, and certain medications. It's crucial to discuss these details with your medical provider before seeking treatment.
