Clear explanation
Why ED happens
ED often results from reduced blood flow to the penis, nerve signaling issues, hormonal imbalances, or psychological factors. Chronic conditions such as diabetes, high blood pressure, and cardiovascular disease are common contributors. Lifestyle factors—smoking, excess alcohol, and lack of physical activity—also play a role.
How ED pills work
ED pills do not create sexual desire. Instead, they support the body’s natural response to sexual stimulation by enhancing blood vessel relaxation. This makes it easier to achieve and maintain an erection when aroused.
Common manifestations and expectations
People may notice firmer erections, improved consistency, or increased confidence. Results vary depending on the underlying cause of ED. Pills may be less effective if nerve damage or severe vascular disease is present.
Diagnosis before treatment
A proper evaluation may include a medical history, medication review, physical exam, and sometimes blood tests. This step helps rule out conditions where ED pills could be unsafe.
Approaches beyond pills
ED management can include lifestyle changes, counseling, treatment of underlying diseases, or other medical devices. Pills are one option within a broader care plan.
