Impotence generally refers to erectile dysfunction, and premature ejaculation is related to erectile dysfunction. More patients may confuse the concepts of erectile dysfunction and premature ejaculation, which is usually caused by psychological or psychiatric factors and is also related to thyroid hormones, prostatitis, neurobiology and other factors. And some patients may also be anxious to have intercourse to prevent erectile failure and rapid ejaculation, resulting in the inability to quickly erect after ejaculation and anxiety and other abnormal emotions, which may lead to the aggravation of premature ejaculation. Meanwhile, erectile dysfunction and premature ejaculation may co-exist, and the incidence of erectile dysfunction is higher in patients with premature ejaculation. In addition, patients with mild erectile dysfunction have less control over ejaculation. Premature ejaculation and erectile dysfunction should be recognized correctly, and if abnormalities occur, it is recommended to go to the hospital in a timely manner to identify the cause of the disease and then actively treat it under the guidance of the doctor.
