Patients with short erection time should undergo neurophysiological examination, penile ultrasound, and cavernosography to identify the cause. Patients with short erection time, also known as premature ejaculation, can be treated with dapoxetine, or Bilevel, for the centrally sensitive type of premature ejaculation. Patients with penile sensitivity may be treated with local anesthetics and behavioral therapy. Patients with midway weakness of the penis caused by arteriovenous fistula can use Vanco to promote erection and follow medical advice on medication, and the inner wall of the blood vessels may recover; patients with midway weakness that is not easily cured can take penile prosthesis implantation.
