If you’ve tried everything for impotence and nothing works, your final option is a penile injection. Puncturing the penis with a needle may not sound like a good way to treat impotence. But this method works in 7O percent of cases and may give both men and women the satisfaction they need.
Three types of medications are used to produce an erection: phentolamine, papaverine, and prostaglandin E1. Both phentolamine and prostaglandin E1 work by interfering with alpha nerves that cause the penis to remain in a limp state. By blocking these nerves, an unrestrained flow of blood reaches the penis and makes it ready for intercourse.
The exact mechanism of papaverine is unknown but it supposedly causes intrapenile smooth muscles to relax, thereby allowing increased blood flow to the penis.
The injections are not as bad as they sound. Patients can learn to administer them from their urologists. A very small needle is used and only a small amount of the medication is necessary. Pain is minimal.
To be effective, the injections must be made at a specific site at the side of the penis. Erection occurs within 10 to 30 minutes and can last for several hours.
The success rate of penile injection therapy varies depending on the medications used. For prostaglandin E1, it can reach as high as 86 percent as one Japanese study reported. However, not one medication is ideal and not everyone is satisfied with this treatment.
“Different doses of drugs have been administered. Doses effective in inducing the first erection are not consistently effective in maintaining satisfactory erections with each successive injection. A need to increase the dose after a while or switch from one medication to another seems to be the standard. Even men who have a fully satisfactory response do not always stay with this form of treatment; about one-third drop out,” according to Dr. Richard F. Spark, associate clinical professor of medicine at Harvard Medical School in Male Sexual Health: A Couple’s Guide.
But there are some problems associated with penile injection therapy. Men who use phentolamine and/or papaverine, for instance, develop nodules and scarring within the penis. There is also the risk of infection, pain, and bruises.
“It was originally believed that papaverine or papaverine/phentolamine injected directly into the penis would remain there and not enter the bloodstream. This has proved not to be the case. Some of the mixture enters the general circulation and causes damage to the liver. Up to 40 percent of men who continue long term treatment can expect to develop at least one abnormality of liver function: mild inflammation,” Spark revealed.
Another problem is priapism or prolonged painful erections that can last for six to 12 hours if higher doses are used. This can be so severe to the point that penile tissue is destroyed and surgery may be the only way out.
“In our study, 486 patients used papaverine. Sometimes the erections would begin normally but it would persist for up to 24 hours. For the first two hours, the wife would have a fantastic time. But more than that, she would complain and it became painful for the man. In 10 percent of patients, there was scarring at the site of injection,” said Dr. Edward John Keogh, medical director of the Reproductive Medicine Research Institute at Queen Elizabeth II Medical Center in Nedlands, western Australia.
There seems to be fewer problems with prostaglandin E1 but its long-term effects are unknown. Because of this, the drug of choice for intrapenile injection therapy has yet to be found.
In spite of this, over 60,000 injections have been given to over 30,000 men in the United States, Japan and Europe. Hopefully, more men will avail of this treatment as more information regarding penile injection surfaces in the next few years. For those with severe vascular disease or in diabetics over 60, however, prostaglandin E1 injections won’t work.

And if they know how to make dentures, they understand what is needed to repair dentures the right way, the first time. But in most cases, the dentists who inspects your broken dentures usually sends their new denture and denture repairs to a dental lab for this work to be completed. How long will it take to get your denture tooth repaired ?When dealing with local dentures dentists, your denture repair can take up to a few weeks to get your denture repair. This is because your dentist will send your denture repair to a dental lab. Just having the denture repair in the mail, to and from its destination would take about a week. Your best solution to getting your denture repair is by using mail order denture repair services. Often the cost for a denture repair through mail order is usually half the cost of that of using a local dentist. Another benefit is the time involved, as your denture repair can be back in your hands in a few days, not weeks with your local dentures dentist. When dealing with a mail order denture repair business always make sure there is a dentist who can inspect and repair your dentures. If the business offers a dentist who repairs dentures, this is perhaps the best of all solutions to getting your denture repaired the right way. Lastly, find out if you can about how the businesses ship your dentures back to you, and if they use additional packaging to secure your dentures for a safe journey back to your home. Avoid using glues to fix your denture tooth :Broken dentures that can still function usually may have a denture tooth missing or a broken denture tooth. Whatever you do, try not to glue back your denture tooth on your denture as you can damage your denture making your denture repair more expensive. Most glue is poisonous, and when dry will flake off into your mouth caused by the constant rubbing of food and saliva on the glue. In addition some glues chemically react differently with your pink denture gums where the glue can warp your dentures beyond a regular denture repair. Home Denture Repair Kits come with Denture Teeth :While there are some denture repair kits may not have the denture tooth you need, one must know that there are virtually hundreds of styles of denture teeth which may make it difficult to find the right denture tooth replacement for your denture repair solution. Denture teeth are either porcelain or acrylic, and each has a different application method when a denture repair is needed. The Porcelain Denture Tooth :The porcelain denture teeth have difficulty adhering to the pink denture acrylic, and with this known, the porcelain denture teeth have extra features to keep the denture teeth in place. The front (anterior) denture tooth is made with two small pins that extrude from the denture tooth. This acts as extra support for the denture teeth to absorb impact vibrations during chewing. The back (posterior) porcelain denture teeth have tiny vent holes, so when the denture tooth is placed onto the denture, the pink denture acrylic will flow into these holes creating a solid bond with the denture gums. The denture tooth is available in different styles :There are many different styles of denture teeth that could be used for a good denture repair. Denture teeth are made to be tall, skinny, short, or fat. They are also made so that the denture tooth may taper to a square end or a rounded end. When the denture tooth is replaced during a denture repair, the denture tooth is closely matched against the different denture tooth features as described above. In addition, overtime, the denture teeth change color from natural ivory to a darker shade of ivory. During a denture repair, the denture tooth shade is closely matched against the existing denture teeth so the denture-repaired tooth will blend seamlessly along with the remaining set of denture teeth.
