Deformed sperm cell. Coloured scanning electron micrograph (SEM) of an abnormal sperm cell showing its double tail. Its tails are lying together,but a pale dividing line is seen between them. A defect such as this greatly reduces the cell's motility,meaning it will not be able to reach 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: x4000 at 6x7cm size | |
