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.
For the legendary vampire, see Count Dracula. Vlad III, known as Vlad the Impaler (Romanian: Vlad ÈepeÈ; pronunciation: [Ëvlad ËtÍ¡sepeÊ]) or Vlad Dracula (1428/1431 â 1476/77), was voivode (or prince) of Wallachia three times between 1448 and his death. He was the second son of Vlad Dracul, who became the ruler of Wallachia in 1436.
