Have you ever found yourself pondering about the size of these unseen swimmers? Well, sperm cells are actually really tiny. In fact, they are some of the smallest cells in the human body, and measure just 0.005cm. To put that in perspective, scientists need a microscope with 400x magnification to see a sperm cell. This is a big contrast in size to the female egg cell that funnily enough is one of the biggest cells in the human body, and is just about visible with the naked eye… well they do say opposites attract!
