Deformed sperm cell. Coloured scanning electron micrograph (SEM) of an abnormal sperm cell showing a "hockey stick" appearance due to residual cytoplasm. This is an immature characteristic in sperm cells,and makes them unable to fertilise an egg cell (ovum). All men have a few deformed sperm in their ejaculate,but an overabundance of them can mean that the man is infertile. Magnification: x3750 at 6x7cm size | |
