Erectile dysfunction (ED) refers to the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Occasional difficulty with erection can happen due to stress or fatigue, but persistent erectile problems are not normal and may indicate an underlying medical condition.
Erectile dysfunction is common, especially in men above 40 years, but it is treatable in most cases. Early evaluation not only improves sexual health but may also detect hidden conditions such as diabetes, heart disease, or hormonal imbalance.
