It helps identify whether erectile issues are consistent, situational, or linked to lifestyle or emotional factors. Understanding these patterns makes it easier to discuss results with a doctor and explore treatment options.Erectile dysfunction happens when a man regularly has difficulty achieving or keeping an erection sufficient for sexual activity. Occasional erection issues are normal, but persistent problems may indicate underlying physical, emotional, or lifestyle-related causes.Physical factors include poor blood flow, nerve damage, hormonal imbalances, and chronic health conditions such as diabetes, high blood pressure, or heart disease. Psychological factors, including stress, anxiety, depression, or relationship difficulties, can significantly affect sexual performance.
