Can vampires reproduce?

Yes, ever since ancient times it has been known that a male vampire can impregnate a human woman. The child is known as a Dhampir. These children have all the powers of a vampire (in ancient times that meant only the power to steal life-force, all this super-power nonsense is late 19th century and Hollywood conceived) but as they are already alive, they have no need to steal life-force. This power lies dormant until they themselves die, or are near death, and they have cause to employ it.

I know of non instance where a female vampire has given birth.
