There are several new, non-invasive techniques for animal sterilization.New advancements in the world of veterinary medicine could soon have a major impact on the way dogs and cats are spayed and neutered. Whether it’s a drug that eliminates the need for surgery, or the application of new techniques that will allow veterinarians and certified veterinary technicians to limit the number of feral and stray animals, the old way of sterilization may soon be coming to an end.

New drug may eliminate need for sterilization surgery

Surgically removing an animal’s reproductive organs is a costly, time-consuming procedure that many pet owners and animal rights’ advocates openly detest. Nonetheless, with America’s 40-year push to spay and neuter dogs and cats in order to better control the pet population, it has become the most common form of sterilization.

Pet owners are often wary of surgery because they believe that it lowers testosterone levels, and ultimately the vibrancy, of their pets. Animal rights’ advocates have long expressed the belief that removal of the gonads is an invasive and traumatizing procedure.1

Now, however, some new, non-invasive sterilization methods are being tried out that could eliminate the need for surgery. Instead, veterinary professionals would be able to rely on implants or the injection a drug into the animal’s testes that would shut down sperm production and block its pathway.

According to The New York Times, one of those newer drugs, Zeuterin, is already being used more commonly in many veterinary clinics. And the drug’s manufacturer hopes that with proper knowledge and training it will become an even more popular alternative to surgery.

Dealing with stray animals

One of the biggest benefits to these new procedures is that they would allow veterinary professionals who work with stray and feral animals to more easily keep their populations in check.

Surgery is not only extremely invasive, it is also costly and time-consuming, which makes treating large animal populations very difficult. With a simpler, less costly, quicker alternative, clinics like the proposed high-volume spay-neuter clinic in San Diego would be able to handle a higher volume of animals, thus making it easier to limit stray populations.2 These new methods would also make it easier to serve lower-income families who often can’t afford to have their pets fixed.

Currently, the Spay and Neuter Action Project and the Feral Cat Coalition offer weekly sterilizations, along with two vans outfitted to work as mobile veterinary clinics, according to But new, cheaper, faster spaying and neutering techniques would enable the groups to offer their services in a more permanent setting.

    I’m in Jacksonville FL. with a feral cat problem. If you know any vet clinics offering this alternative in my area, please email me. Thank you very much.

    I think that this is an amazing idea. A drug that eliminates a need for surgery to neuter/spay pets is very innovative and could be a major stepping stone in the veterinary world. With so many feral cat issues across the US like on the big island of Hawaii, and many others, the new idea of a drug administered as a shot could save time for veterinarians everywhere and they could spend their time doing more research or more surgeries to help other pets. The idea of a simple sterilization method like Zeuterin, I agree, be especially helpful in low income neighborhoods as mentioned in the article. The fact that we can eliminate our pets’ distress of going to the vet with a simple shot rather than putting them under to get neutered or spayed would greatly benefit them. Not only that, but it would decrease buildup in the veterinary office as well. The use of this new drug becoming more commonly used in clinics is a step in the right direction. It’s unbelievable that this new drug is more cost effective and is as noninvasive as it is. This drug could change the lives of so many families, considering that many avoid getting pets because of surgeries like these costing so much. One thing I would like to know is how successful is this drug in making the animals 100% sterile? Does it have adverse effects that might change the consumer’s mind? Overall, I am behind this! I am so proud of the veterinary world today, thumbs up!
