New Drug ‘Chemspay’ Could Sterilize Female Dogs Without Surgery

A new drug could be the non-surgical alternative to spaying female dogs and a major change for animal shelters.

Chemspay is a contraceptive drug that can either be administered orally or through injection, and based on trials significantly reduces the number of eggs in a female dog’s ovaries, making them sterile.

The Arizona Republic reports:

Dr. Loretta Mayer was looking for a way to artificially induce menopause in mice so they could be used to study human diseases when she and another scientist developed a drug that they realized also could be used to sterilize female dogs, removing the need for expensive and painful surgery.

The first drug they developed, dubbed “mouseopause,” eliminated the eggs in a mouse’s ovaries. Mayer looked for ways to adapt the drug for other animals, including “ContraPest” in rats, as an alternative to poison in areas where animal overpopulation is out of control.

“I would really like to see us do things that improve our environment and are compassionate to other beings,” Mayer told the Republic. “My passion, without question, is to stop killing animals, however we might do that.”

Mayer began testing Chemspay on dogs in 2004 on Arizona‘s Navajo Reservation when the tribal animal shelter’s director asked for her help with their feral and stray dog problem.

“He said to me, ‘If you could do for a dog what you do for a mouse, I wouldn’t have to kill 400 animals a month,” Mayer said. “This technology, if successful, will really have a huge impact on unwanted dog populations.”

In Arizona, thousands of dogs and cats are euthanized in overcrowded animal shelters every year. According to the Republic, the Arizona Humane Society performed nearly 20,600 surgical sterilizations on dogs, cats and rabbits in the past year, at a cost of almost $2 million.

Food and Drug Administration approval is still at least six years away, but Mayer hopes to begin FDA trials in Arizona within the next few years.

Chemspay is not the first drug alternative to surgical sterilization: Neutersol, for male dogs, was approved by the FDA but taken off the market in 2005 due to a manufacturing dispute. GonaCon is a contraceptive currently used on deer populations, and is being studied for use in dogs and cats.

Check out this 2009 report in which Mayer discusses the development and use of ContraPest in curbing rat overpopulation in rice fields:

    Actually, it sounds pretty good to me. I’m sure the same OMG comments were made when the female birth control pills were developed. Obviously there hasn’t been a problem so far. Yes, yes, I realize that this is permanent and BCP is temporary, but a bit more research might have made to two medicines similar. I understand your concern, Nevertheless, it might reduce the thousands of dogs (and cats?) killed yearly by overcrowded shelters.

      Personal responsponsibility in the ownership of pets could also reduce the numbers of “unwanted pets” immediately. Don’t allow your pet to reproduce, don’t get a “throwaway” pet, don’t breed your pet just because you “love it,” realize that your pet (or “breeding animal”) is NOT PERFECT and breed only those animals worthy and needed to be bred.

      I am a sheep and cattle farmer and a working dog trainer and breeder for over 45 years and in contact with (and consider myself still responsible for) any puppy I have produced during that time to it’s loss, hopefully in very old age!

    I had heard about this kind of drug before and thought it’d be better for controlling the wolf population then shooting them dead for sport. I’m also into animal rescue and the euthanization of unwanted pets and ferrals is astounding. Rescues pay for spaying and neutering unwanted pets before finding good homes for them and this would cut down on their cost as well as taxpayer cost. As far as using this on unsuspecting humans; may God NOT have mercy on their souls.

    Mandatory vaccination!! or else…….my theory was that that was dry run for something bigger.

      Scale back the size, scope , and force of the government if you want to reduce the power gov’t has over our daily lives. This government is screwing us plebs into the floor anyway and many on the left believe wholeheartedly that population control of humans is necessary for planet survival. I am sure Environmentalists will embrace this technology as it hold promise in the human population problem.

    Bill Gates, of Microsoft, is working on a sterilization vaccine, and a method of using ultra sound on male scrotums to render males sterile for up to six months. He was also working on a substance that could be applied to the skin for the purpose of sterilization. The one world government people intend to reduce the surplus population of the earth, making it more habitable for the elite and their progeny.

    Ont thing that needs to be studied (and probably will not be considered for study) is whether the drug passes thru the urinary tract in a complete enough form to sterilize fish, frogs etc. Or how much might get into the water supply that eventually makes it’s way into our drinking water.

    This is scary stuff. You already can’t attend school without certain vaccinations. I don‘t know how applicable to humans this drug would be but with centralized mandated health care alot of things could be done for the individual and society’s ‘good’. They could just tell you it‘s something else or include the drug with some other ’preventative therapy’…

    This sounds like a wonderful advent for controlling animal populations, but it sends a chill down my spine at the thought of it being used against human populations. If all it took was a quick seizure of a woman, pry her mouth open, and then spray the drug into her mouth to dose her with enough to kill all of the ova in her ovaries, this is genocide in an aerosol can.

    I’m sure the eugenicists still running around would deem it humane to come out with grape, strawberry, and banana flavoured ChemSpay cans.
