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.
In Bram Stoker's novel, Dracula, a young Englishman, Jonathan Harker, visits Bistrita and spends a night at the Golden Krone Hotel (Hotelul Coroana de Aur) on the eve of St. George's Day before continuing his journey east to Count Dracula's castle.
