Spermatogenesis is the process of forming sperm cells by meiosis (in animals, by mitosis in plants) in specialized organs known as gonads (in males these are termed testes). After division the cells undergo differentiation to become sperm cells.
The Dracula of fiction lived in a place that was based on Bran Castle in Transylvania. Bram Stoker never visited Romania. He depicted the imaginary Dracula's castle based upon a description of Bran Castle that was available to him in turn-of-the-century Britain.
Transylvania is legendary as the home of the vampire Count Dracula, based on the exploits of a Romanian noble, Vlad the Impaler. But mythical ghouls have been the least of the problems endured by this Eastern European region, which was invaded by barbarian tribes, Hungarians, Mongols, Turks, Hapsburgs, and Soviets.
