I think in the Mercy Thompson urban fantasy series the problem was not that there were no female werewolves (the main species that's interested in the titular protagonist), but the fact that in this version of lycanthropy, werewolves literally have to shift into their wolf forms during the full moon--a process that a pregnant werewolf's fetus generally does not survive. So in order to have children (which most of them wanted to do), the male werewolves in this series usually had to mate with regular human women. Our heroine Mercy is a extremely rare third option, in that she's descended from a kind of Native American coyote shifters who are sufficiently capable of controlling their shape-shifting at all times that the phases of the moon have no effect on them. This ability tends to get the attention of various local male werewolves, although as far as I'm aware, even after Mercy eventually settled down with one of them, they haven't had any kids yet (possibly because he already has a daughter from his first marriage to a human woman).
