Erectile Dysfunction is defined as the persistent inability to erotic achieve or maintain an erection sufficient for satisfactory sexual performance. Although commonly associated with aging, erectile dysfunction can occur in men of all age groups.
The process of erection involves a complex interaction between the nervous system, blood vessels, hormones, and psychological factors. Sexual stimulation triggers nerve signals that increase blood flow to the penile tissues. When these tissues fill with blood, the penis becomes erect.
Several medical conditions can interfere with this process. Cardiovascular diseases such as hypertension and atherosclerosis reduce blood flow to the penis. Diabetes mellitus can damage nerves and blood vessels, further impairing erectile function.
Hormonal imbalances, particularly low testosterone levels, may reduce sexual desire and contribute to erectile difficulties. Psychological factors such as anxiety, depression, and stress also play an important role.
Treatment options have evolved significantly over the past decades. Oral medications known as phosphodiesterase type-5 inhibitors are commonly prescribed to improve blood flow to the penis. Other treatments include vacuum devices, penile injections, hormone therapy, and surgical implants.
Because erectile dysfunction may indicate underlying cardiovascular disease, physicians often view it as an early warning sign of broader systemic health issues.
