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.
