A male desexed Guinea Pig is called "Neutered", and a female desexed Guinea Pig is known as "Spayed".
The male guinea pig is called a boar and the female is a sow because of their name "pig", even though they're not pigs. A male pig is a boar and a female pig is a sow, so the guinea-pigs have been named after them.
