faye its chemical sterilization. they inject the testicles with this stuff. i remeber a long while back one of our reps coming in and talking about it but i didn't pay a whole lot of attention to him when he was talking, so i dont remember exactly how it works.
Faye, Scout is right. The dog is is sterilized by injection instead of surgery. The testicles stay in tact. Right after I saw it on TV here in Houston, and that SNAP was using it, I mentioned it on TP, and ltlgto posted an article about it. He may be able to tell you more.
Yeah, I have a few neighbors that let their dogs run all over the country and won't get them fixed....therefore shelter pups in the making.....but now that you mention that..........let's see i know a few guys I would love to use it on.....:)
I had a feeling Faye that you just might be talking about some human males. That is exactly what SNAP is trying to do, going around getting people to bring their dogs to be sterilized, cutting back on the unwanted puppies. It is a lot less expensive than the traditional neutering.
Pups 3-10 months old are injected in each testicle, which causes them to atrophy and the dog is therefore sterile. From what I've read, there are very few complications (mild swelling of the testicles for 1-2 days, most dogs don't need any pain meds, even for the injections) BUT this procedure only cuts the testosterone by about 50%, versus the 90-95% in traditional neutering. There is speculation that some of the behaviors "believed" to be reduced by traditional neutering (marking, mounting, roaming), may not be as reduced with Neutersol because of the remaining testosterone. Many other articles I've read state statistics that indicate many of those behaviors are not decreased even by traditional neutering in the majority of dogs....the old story of using statistics to support any argument. There are places (like Houston) where the procedure has been done for free or very low cost, but normally it runs about the same as traditional neutering in my area. Hopefully someone will pop up on here with some personal experience or something else I can read. Thanks guys!
Neutersol approval has been a long time in coming. The HSUS has been actively involved in pursuing alternatives to surgical spaying and neutering for decades, and worked with the late Dr. Mostafa S. Fahim, the developer of Neutersol, in early field trials of the product.
In contrast to the standard surgical castration, which removes the testicles, Neutersol is a zinc and l-arginine-based compound injected into each testicle, causing them and the prostate to shrivel. With just one quick shot, the solution causes permanent sterility. While anesthesia may be needed for the procedure—which, at this point, is approved only for male dogs age three to ten months—the time your pooch spends at the veterinarian will probably be somewhat shorter.
"Some people are uncomfortable with surgery and anesthesia," said Dr. Bruce Addison, the founder of Addison Biological Laboratory, which markets the drug. Addison hopes that the ease of Neutersol will entice more people to sterilize their pets and help solve the pet overpopulation problem.
The use of Neutersol, however, will not completely stop testosterone production in dogs, leaving open the possibility that the drug will not eliminate hormone-related disease such as testicular cancer or prostate disease. Both possibilities are eliminated when a dog is surgically neutered.
Addison said that they are addressing these things with the FDA, and that while he didn't want to get ahead of the agency's review of its research, he feels that testicular cancer is not an issue because Neutersol atrophies the testicles by 77 percent, eliminating most of the cells that could potentially cause cancer.
Another concern is that the continued production of testosterone may not decrease unwanted secondary behavioral characteristics, such as roaming, marking or aggression, which surgical castration is thought to tackle. While Neutersol's 41% to 52% decrease in testosterone levels could also have some of the same positive behavioral effects as surgical castration, no tests have been done comparing dog behavior and the use of the drug. In fact, the drug, on its packaging, claims that as with surgical neutering, Neutersol may not alter unwanted male behaviors.
Side effects to the drug include testicle swelling within 24 hours of injection, which is a normal reaction to the compound; other potential side effects include vomiting, loss of appetite, lethargy, and diarrhea.
"Although this product is limited in scope, we're excited about the FDA approving this first step in chemical sterilization," says Stephanie Shain, Director of Companion Animal Outreach at The HSUS. "For people who may be unnecessarily squeamish about having their dog surgically neutered, Neutersol may be a suitable alternative for them to explore."
Given Neutersol's limited usage for puppies, Addison said that they are moving forward with testing on older dogs and cats. Scientists have tried chemical sterilization on these populations in the past, but the results thus far have been mixed. If you have an older dog who is not neutered, your best bet is not to wait until chemical sterilization is available, Shain says, but instead to talk with your veterinarian to have dog altered the "old fashioned" way.
With the number of dogs and cats entering animal shelters reaching eight million annually, and almost half of them being euthanized, unplanned and irresponsible breeding make the pet overpopulation problem one that also costs taxpayers millions, Shain notes. By taking the time to neuter or spay your pets, she adds, you are doing your part to end the tragedy of unwanted pets.
Because Neutersol is such a new product, many veterinarians may not yet have it in stock. Based on those who do, however, it is expected to cost about the same as surgical neutering. Your veterinarian can fully explain the benefits of neutering to you, along with the best age at which to sterilize your pet, and whether you should go the chemical or surgical route.
