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.
It's one of those so-called facts that everyone knows: Bram Stoker's character Count Dracula was loosely based on Vlad the Impaler. But while there's no doubt that Stoker took the name from Vlad III's patronymic, it's doubtful that the Impaler was actually the basis for the famous vampire.
