[Q]: Sperm is the male reproductive cell and is derived from the Greek word ( σπέρμα ) sperma ( meaning `` seed '' ) . In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the `` male '' or sperm cell . A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium . Sperm cells can not divide and have a limited life span , but after fusion with egg cells during fertilization , a new organism begins developing , starting as a totipotent zygote . The human sperm cell is haploid , so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell . In mammals , sperm develops in the testicles , stored in the epididymis , and is released from the penis .
