While anything is possible in SciFi, interspecies breeding can lead to sterile offspring (e.g. mules). However, I don't think they ever implied Spock was sterile it might not be an issue.
Conversely, I'd assume the cross breed would probably exclude females.

And no, I won't say _why_ they would have to :)
