We have a male calico with wee wee and balls. He is sterile he is also 10 months old .

I have a friend that has a male Tortoise shell. I had a calico once... don't know what happened to her.

Sometimes cats with those genetics are not clearly male, but hermaphrodites. But always sterile

ok so my cat had kittens and two of them are clearly calico and yes one of them is a male . not sure about it being sterile or not but for those of you who think all calico male cats can't breed are wrong!!! not sure how to upload pic but i will try to upload the pic

My vet told me she had confirmed a male calico, but they are extremely rare. He's the only one she has seen, though we had an article in the paper about another one.

A lot of time male calico cats have funky sex chromosomes. Calico cats are chimeric individuals and this condition is often X-linked. I don't remember a lot of the specifics, but yes male calicos are possible, just very very rare. Due to their funky genetics, I would think most of them would be sterile.

If memory serves, and it may not, most male calicos are XXY and are sterile. I don't think most calicos are chimeras, but some may be.

I think I was mixing up chimera and mosaics. I found a good website to explain though! Cats are unique because you can visibly see the results of X-chromosome inactivation, whereas in other mammals you generally cannot. I'm pretty sure you are correct about the XXY males, if I'm remembering my genetics correctly!
