A spermatozoon on the uterine mucosa. False-colour scanning electron micrograph of a spermatozoon floating over the endometrium, the internal wall of the uterus. Spermatozoa have pear-shaped heads about 7 microns long and a tail about 60 microns long. This image also shows the two different types of simple columnar cells which populate this area ciliated (orange bottom left) and secretory (pink, yellow). During their journey through the uterus towards the Fallopian tubes spermatozoa undergo a capacitation process which enable them to penetrate and then fertilise an egg.
