At 56, my penis can no longer get erect, but there was no problem last year. Why is it that a 56-year-old man's penis cannot get erect?

A 56-year-old man experiencing inability to achieve penile erection is suffering from erectile dysfunction. As men age, erectile function tends to decline, especially when sex hormone levels are insufficient; such individuals should visit the urology department of a reputable public hospital for evaluation. Middle-aged men over 56 often have chronic conditions such as hypertension and diabetes, which can lead to penile arterial stenosis and inadequate blood supply to the corpora cavernosa, resulting in reduced penile erection hardness or inability to achieve erection.
