Erectile dysfunction or ED refers to the inability to attain and maintain a sufficient erection for sexual activity. Erectile dysfunction is the most prevalent sexual issue reported by men, as around 30 million males are affected by it. Occasional erectile dysfunction is not usually a reason for alarm. If erectile dysfunction is persistent, it may create stress, diminish self-confidence, and exacerbate relationship issues. Problems obtaining or maintaining an erection may also indicate a health problem that requires treatment and can be an indicator of cardiovascular diseases.
