Erectile dysfunction (ED) is a condition in which a man has difficulty achieving or maintaining an erection firm enough for sexual intercourse. This can be due to various factors, including physical, psychological, or a combination of both. Physical causes may include heart disease, diabetes, hormonal imbalances, or side effects from medications. Psychological factors can involve stress, anxiety, depression, or relationship issues. It is essential to consult with a healthcare professional to determine the underlying cause of ED and develop an appropriate treatment plan.
