The tip of the penis has a mushroom-like shape for the same reason why your nose is shaped like one. This is due to the way in which it develops during fetal development, according to Professor David Ralph from Queen Mary University of London. The penis and nose both develop from similar tissues and end up with a similar shape, although they do so in different ways. The male sex organ grows out of tissues that will eventually become the urethra, while the nose develops out of tissues that will eventually become cartilage.
The urethra is made up of erectile tissue, which contains blood vessels that are full of blood. This means that when it’s flaccid, there’s not much room for expansion and it can’t grow very much. When it becomes erect, however, those blood vessels fill with blood and swell up. This allows for more space within the urethra to expand and make room for ejaculation.
