The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control. As of 2019, only contraceptives are commercially available.
The male hormone, testosterone, is produced in limited quantities following treatment with Zeuterin, but after two years, testosterone production is similar to that in untreated dogs. [1] The continuing presence of testosterone means that, unlike surgical castration, chemical castration does not remove the risk of testosterone-associated ...

Castration has also been known to reduce aggression in male dogs (in some cases ...
