Non-Surgical Neutering: Chemical Castration for Dogs

A new non-surgical method of sterilization for male dogs promises results similar to surgical procedures, while leaving testicles (and perhaps your dog’s pride) intact.

According to Ark Sciences,the Zinc Neutering process renders dogs sterile without disrupting the endocrine function of the testes.

“What is Zinc Neutering? Zinc Gluconate (What is Zinc Gluconate? ) neutralized with L-Arginine (What is L-Arginine?) is the first compound ever to be approved by the FDA as safe for sterilization. It uses Zinc Gluconate (a trace element) and Arginine (an amino acid), both of which are essential for the body. In fact, they are health supplements that millions of us use every day.

A specific concentration of Zinc Gluconate neutralized with Arginine creates permanent sterilization with no adverse reactions needing medical treatment nearly 99% of the time (see the question on side effects below for other minor reactions). The mechanism is so targeted and precise that in an FDA study, it virtually stopped spermatogenesis in 99.6% of young dogs 3-10 months old, rendering them sterile, while maintaining the endocrine function of the testes.”

After the injection, the Zinc Gluconate solution diffuses in all directions from the center of the testis. The specific concentration of Zinc (a gentle spermicide) used in our formula destroys spermatozoa in all stages of maturation in the seminiferous tubules and in the epididymis. The seminiferous tubules, which were replete with spermatozoa, are now emptied and collapse.

Given the reduced (or nearly non-existent) recovery period and the potential for reduced cost, this looks rather promising – provided that there are no long-term side effects of consequence.

  1. hell no. we try not to over vaccinate our dogs against real diseases…I wouldn’t go putting this crap in their body. besides, I saw some pushers of this procedure at a rescue conference and got the same slimy feeling as if I’d met the ambulance-chasing lawyers. Hard to get past the dollar signs in their eyes.

    • Actually, it’s cheaper than traditional neutering. Many vets don’t want to switch because its less “profitable”.

  2. Possibly. What I like best about it is it keeps endocrine unction, which is all important for the overall health of the dog. I’d prefer that it was tried on human males first though, before subjecting my dog to it. 😉 .

  3. I left a really long comment on the story itself. They aren’t yet sure of the possible long-term side effects and I wasn’t sure if it would protect against testicular cancer, prostate issues, wandering behavior, aggressive behavior, etc. like normal neutering does seeing as how the amount of testosterone is not affected and the testicles are still present. Personally, I don’t know if I’d feel comfortable going this route right now, but I think it could be extremely useful for mass neutering efforts for stray animals and for people who are afraid of neutering “changing their animal”, blah blah blah. My boys are both neutered and they don’t miss their balls in the least bit, haha.
