Caption

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. Magnification: x2200 at 6x7cm size.
