Abstract
Erectile dysfunction (ED) is a disorder during which a man has difficulties in achieving or keeping a hard enough erection for sexual intercourse.
Although discussing ED might be embarrassing, it is common, and a diagnosis can be made swiftly. A physical examination and some simple questions regarding medical history are frequently all that is required.
ED can be a symptom of a variety of underlying diseases and is a significant but unused risk factor for cardiovascular disease. ED can be a result of any illness condition that affects the penile arteries, nerves, hormone levels, smooth muscle tissue, corporal endothelium, or tunica albuginea.
ED has been linked to poor overall health, and emotional disorders are likely to the experiencing of erectile dysfunction.
Ear lobe crease is a furrow that runs from the tragus to the auricle. Ear lobe crease come in a variety of shapes and sizes commonly known as Frank’s sign.
There is a link between ear lobe creases and heart disease, notably coronary artery disease (CAD). Many studies have connected ear lobe creases to an increased risk of cardiovascular diseases such as stroke and heart attack.
The precise mechanism behind the link between ear lobe creases and CAD is unknown, however it might be connected to alterations in the blood arteries that feed the earlobe.
The anterior tragal crease is a vertical line that runs anterior to the targus of the ear.
The anterior tragal crease (ATC) is a potentially predictive clinical sign of atherosclerosis. It is a noticeable crease that may aid medical professionals in identifying individuals at risk for atherosclerosis.
We search for the possible correlation between ED and ear creases (ELC, ATC).
We use a new grading system for detect the grade of ear creases (ELC and ATC) and correlate it to erectile functions of the participants according to IIEF-5 questionnaire.
We conclude that there is significant positive correlation between grade of both ELC, ATC and combined ELC+ATC and presence & severity of ED.
