Mature male germ cells that develop in the seminiferous tubules of the testes. Each consists of a head, a body, and a tail that provides propulsion. The head consists mainly of chromatin.
Reproductive cell of the male.
Also known as sperm, the male sex cells that fertilize female eggs. Sperm is found in semen, the thick fluid that is secreted by the male reproductive organs and is discharged from the penis upon ejaculation during sexual inters-course. Semen contains millions of sperm, which have well-defined heads, midsections, and tails and move with swimming motion. Whenever sperm are released by the penis into the vagina, they can travel through the uterus into a fallopian tube, where they can fertilize an egg, resulting in pregnancy. To prevent pregnancy, it is important for partners to use an effective means of contraception.
The male reproductive cells, which is the plural form of spermatozoon.
