3162. Vasectomy for a male guinea pig is not possible

 No guinea pig owner has had requested for such surgeries," I told the owner who wanted vasectomy for his male guinea pig so that he will retain his male characteristics. "I don't want him to be effeminate, as he is affectionate towards the female now."

The owner has had to monitor both to prevent pregnancy. I asked for photos of the guinea pig and measurements. He sent them as follows:

 

 

 

Thank you for the excellent photos. A physical examination is needed. Please come at 10 am with the guinea pig food and water.

Vasectomy is not recorded to have been done on guinea pigs. I showed the owner the illustrations of vasectomy in a dog. "The vas deferens is much bigger and longer as the dog is much bigger than a guinea pig," I said to him. "In the adult male dog, the vas deferens is around 4 mm in diameter. 1 cm
of the vas deferens is cut off."  In the guinea pig, the vas deferens is around 1 - 2 mm and therefore, not of sufficient size for ordinary surgery to pull it out to ligate."

The owner agreed to the neutering. This was done.
