More information
Sperm is the male reproductive cell. 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 , is stored in the epididymis , and released from the penis.

A new sperm separation technique may one day allow prospective parents undergoing IVF to choose whether they have a boy or a girl before fertilisation takes place, researchers say. Scientists in Japan have reported a new method which allows them to separate mouse sperm carrying an X chromosome from those carrying a Y chromosome, meaning that sperm can be selected based on whether they will result in female XX or male XY offspring when used to fertilise an egg. The researchers say they made their discovery as part of a project to unpick and understand the differences between sperm carrying an X chromosome or a Y chromosome, noting that the former carries far more genes than the latter.

Susan S. Sperm hyperactivation is critical to fertilization, because it is required for penetration of the zona pellucida. Hyperactivation may also facilitate release of sperm from the oviductal storage reservoir and may propel sperm through mucus in the oviductal lumen and the matrix of the cumulus oophorus.
