According to folklore, a male vampire can father children with a living woman. Sometimes known as dhampirs, such children exhibit unusual tastes for blood, and some have advanced hearing, smell and taste.
A vampire-child has the option of becoming a real vampire when death is near without the intervention or bite of a real vampire. Most dhampirs do not wish to become real vampires, and many ask to die by burning. Dhampirs may live a bit longer than their human parent.
University of Arizona professor and vampire specialist George Gutsche points out that conception between a vampire and a human should be considered necrophilia, since a vampire is essentially dead. Necrophilia is illegal in most countries.
