Human sperm (spermatozoon, spermatozoa), coloured scanning electron micrograph (SEM). A spermatozoon (motile male sperm) joins an ovum (female egg) to form a zygote. A zygote is a single cell, with a complete set of chromosomes, that normally develops into an embryo. Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring (excluding mitochondrial DNA). Magnification: x870 when shortest axis printed at 25 millimetres.
