Gamete \Gam"ete\ (g[a^]m"[=e]t; g[.a]*m[=e]t"; the latter usually in compounds), n. [Gr. gameth` wife, or game`ths husband, fr. gamei^n to marry.] (Biol.) A sexual cell or germ cell having a single set of unpaired chromosomes; a conjugating cell which unites with another of like or unlike character to form a new individual. In Bot., gamete designates esp. the similar sex cells of the lower thallophytes which unite by conjugation, forming a zygospore. The gametes of higher plants are of two sorts, sperm (male) and egg (female); their union is called fertilization, and the resulting zygote an o["o]spore. In Zo["o]l., gamete is most commonly used of the sexual cells of certain Protozoa, though also extended to the germ cells of higher forms.

Douglas Harper's Etymology Dictionary

"male seminal fluid," late 14c., probably from Old French esperme "seed, sperm" (13c.) and directly from Late Latin sperma "seed, semen," from Greek sperma "the seed of plants, also of animals," literally "that which is sown," from speirein "to sow, scatter," from PIE *sper-mn-, from root *sper- (4) "to strew" (see sprout (v.)). Sperm bank is attested from 1963. For sperm whale see spermaceti.

Sperm (album)

Sperm is the second studio album by the German band Oomph!. This album would drastically change the direction and sound of the band from their heavily synthesizer-based, EBM debut album.

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 cannot 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 and is released from the penis. It is also possible to extract sperm through TESE. Some sperm banks hold up to of sperm.
