Deformed sperm cell. Coloured scanning electron micrograph (SEM) of double-tailed sperm cell,or spermatozoon. A sperm cell's motility may be seriously affected by having multiple heavy tails. All men have a few deformed sperm in their ejaculate,but an overabundance of them can mean that the man is infertile. Also,as men age the number of abnormal sperm cells they produce increases.
