The Guinea Pig Zone - Where the Passionate Piggy People Go!
Neutering is the surgical removal of parts of the reproductive system, rendering an animal sterile and unable to produce offspring. Neutering or 'spaying' a female involves removing the womb and ovaries (an ovariohysterectomy). Neutering or 'castrating' the male involves the removal of the testicles. The vet usually makes a small incision on each scrotum and surgically removes the testicles from within.
Just a note on the word: Some of us think we 'neuter' males and 'spay' females, but the word 'neuter' is actually gender neutral and applies to both sexes. Other terms used interchangeably with neutering are 'altering' or 'fixing.' However, for the most part, we will also use the term neuter rather than castration to refer to neutering males.
The only valid, non-medical reason to neuter your male guinea pig is because you have a female you want him to room with. Neutering does little to change the behavior of aggressive guinea pigs, unlike the effect it has on other types of animals. Likewise, neutering does little to curb mounting or sexual behavior. It will prevent unwanted pregnancies. There is no need or reason to neuter two boars living together. If they don't get along now, neutering won't help. Please see the social life page for more discussion on issues related to pairing up guinea pigs. Please see the breeding page for more information on the dangers and concerns of breeding.
Are risks involved in neutering? Yes. The risks are detailed below. However, they can be minimized. Are there risks in keeping two opposite-sex fertile animals in the same house? Yes. Even with the best of intentions and diligent practices, accidents can happen. Accidental pregnancies can result in the death of a sow or serious health problems requiring major veterinary care. Can those risks be minimized? Yes. Can either risk be completely eliminated? No.
Please be aware that as with any surgery, even with a healthy animal, the best vet, and proper after-surgery care, there is a chance that your guinea pig may not make it. Only you can weigh your options and determine the best course for you and your animals.
