The face sculptor in Riften says she can only work with the living if you go to her as a vampire, which means, for all intents and purposes, vampires are considered to be undead in TES. This is supported by the fact all undead spell and enchantments work on vampires as well. So, my logic is, no... Vampires wouldn't be able to breed...

Considering the Gray Prince, though, perhaps a male vampire may impregnate a mortal woman as the sperm may live long after the body is dead. However, it would be highly unlikely a female vampire would be able to sustain pregnancy with a dead (undead) womb.

That being said, I see no reason why werewolves wouldn't be able to reproduce, so I'd imagine lycanthropy to alter genetic information, thus making it a genetic condition which would be passed down on to the child.

As far as a male vampire impregnating a female werewolf... Damn... No clue. Would definitely be interesting to see in a future TES game, though - a hybrid form between the two. Molag Bal and Hircine could even have a hand in the story of that, both battling for the influence over the hybrid.

You raise excellent points :)
