In my opinion there are two possibilities for Kaneki: either his sperm is still human and so he could produce offspring only with other humans (as a female ghoul's body would simply digest the fetus), or it is damaged by RC cells and so he's pretty much sterile. I find it extremely unlikely for his sperm to turn into a ghoul one's just because he got a transplantation and Ishida's done a fairly good job with biology so far, so I don't think he would change this for the sake of making someone a happy family (remember he considers parental figures useless and annoying lol).

We don't know if Eto was fertile, since most natural hybrids are sterile, but every now and then there's a fertile one.

As for Takizawa, his sperm was probably checked simply to see if/how much it is damaged. Kanou probably didn't have that chance with Kaneki and Takizawa is probably the second best developed male specimen.
