Impotence, also known as erectile dysfunction, is a condition in which a male patient is unable to have an erection for a long period of time, thus causing an inability to achieve fulfillment in sexual intercourse. There are many causes of impotence in young people, which may be due to organic disorders, acted upon by psychological factors, or related to bad habits. Common psychological factors include lack of sexual arousal, low mood of the sexual partner, and mental illness. Organic erectile dysfunction may be related to anatomical or structural factors, traumatic factors, and endocrine factors. For example, circumcision, hyperthyroidism, hypogonadism, and penile fracture may cause erectile dysfunction. Young people are prone to frequent masturbation, a bad habit that can cause a decrease in the sensitivity of the penis, making it difficult to get an erection. The causes of impotence are complex, and young people who still can’t have a normal erection after stopping masturbation for a period of time should go to the urology department in time to see a professional doctor.
