A mature male sex cell, which is ejaculated from the penis and is capable of fertilising an ovum. also called sperm (note: the plural is spermatozoa.) comment: a human spermatozoon is very small and is formed of a head, neck and very long tail. a spermatozoon can swim by moving its tail from side to side. the sperm are formed in the testes and ejaculated through the penis. each ejaculation may contain millions of sperm. once a sperm has entered the female uterus, it remains viable for about three days.
