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.
Bran Castle is a beautiful medieval castle located in the picturesque Bran village, Brasov County. Build directly on the rocks, the castle was built initially to protect the frontier between Transylvania and Tara Romaneasca. Somehow it became known all over the world as Dracula's Castle, but this is only a myth.
