Behind Human / Animal Castration / Spaying / Neutering part 1

“Spaying” and “neutering” are surgical procedures used to prevent pets from reproducing. In a female animal, “spaying” consists of removing the ovaries or uterus and ovaries. The technical term is ovariectomy or ovariohysterectomy. For a male animal, “neutering” involves the removal of the testicles, and this is known as castration https://perma.cc/5QNY-8FAX

Although castrated and intact males may differ in their social behaviour (Kaufmann et al. 2017), there was no significant difference between chemically castrated and intact Swiss military dogs in their working ability in the standardised military test series.

Overall, our results on effects of chemical castration in dogs reveal similar effects to those of surgical castration on the performance of pouched rats in mine-detection (Edwards et al., 2015).

Similarly, the present study found no evidence for an effect of chemical castration on the working ability of male Swiss military dogs.

There are two techniques for sterilization known as surgical and chemical. Surgical castration removes the testes from the scrotum via an incision in male animals. This method is effective, but infection or bleeding can become a problem and it is also time consuming, not cost-effective and needs skilled surgeons. Other in situ noninvasive approaches have been used which include immune-castration and chemical castration and more recently natural oil castration.

Also, unlike surgical castration, this kind of chemical sterilization (Neutersol, Esterisol) does not eliminate gonadal sources of testosterone (Kutzler and Wood, 2006; Jana and Samanta, 2011).

On any given day in the United States, there are an estimated 70 million homeless dogs and cats struggling to survive. Homeless dogs and cats on the streets get hit by cars, are vulnerable to attacks by other animals and cruel people, and contract, spread, suffer and die from contagious diseases.
