Impotence Basics

Impotence is the inability to attain or maintain an erection of the penis that is firm enough for sexual intercourse. To initiate and maintain an erection, the penis must fill with blood. Nerve signals stimulate this engorgement. They prompt the blood vessels in the penis to expand so blood can fill it. Meanwhile, other blood vessels constrict, trapping blood inside.

Impotence can be caused by a venous leak. If a leak in the blood vessels in the penis allows blood to escape, an erection may not be attainable, or may not last long. This can be caused by injury or disease. This condition may also be caused by neurovascular function. An erection cannot be attained if nerve signals do not prompt blood vessels to expand or if blood flow to the penis is reduced. Nerve dysfunction can also diminish feeling in the penis resulting in impotence. Diabetes can interfere with nerve signals. Arteriosclerosis (hardening of the arteries) can cause reduced blood flow. Peripheral neuropathy, spinal cord injury, and surgery can also damage nerves. Many medications also cause erectile dysfunction through this mechanism. Finally, impotence can be a direct result of psychological factors. The brain initiates many of the nerve signals required for a successful erection.

Treatment options include:

  • Sildenafil (Viagra) - taken orally up to once a day, 30 to 60 minutes before sexual activity
  • Alprostadil - either injected into the penis or inserted into the urethra as a suppository
  • OralTestosterone - only for men whose impotence is caused by low testosterone levels
  • Vacuum Devices
  • Plastic cylinder for the penis
  • Hand pump for pumping air out of the cylinder
  • Elastic band for holding the erection after removal of the cylinder
  • Vascular Surgery - repairs venous leaks, and has been shown to be effective in some cases
  • Penile Implants - semirigid, malleable and inflatable implants that are surgically inserted into the penis
