What Is Sperm?

Answer:
Sperm comes from the Greek word sperma, which means seed, and it is the male reproductive cells.

In reproduction referred to as anisogamy and oogamy, there is a difference in the size of the gametes where the smaller one is referred to as the male or sperm cell.

The human sperm cell is haploid, in order for its 23 chromosomes to join the 23 chromosomes of the female egg in order to form a diploid cell. A uniflagellar sperm cell that is motile is known as spermatozoon, and a non-motile sperm cell is referred to as a spermatium. Sperm cells are unable to divide, unlike other cells, and they have a short life span. After fusing with the egg cells during fertilization, a totipotent zygote is formed which can potentially become a new organism. The spermatozoa of animals are produced through a process called spermatogenesis inside the male testicles through meiotic division. They leave the male body in fluid called semen. The sperm cells of mammals can survive for up to three days inside the woman’s reproductive system.

The sperm cell consists of three parts: a head, a midpiece, and a tail. The head contains a nucleus that contains densely coiled chromatin fibers which are surrounded an acrosome, which contains enzymes that are used to penetrate the female egg. The midpiece has a central filament core that has many mitochondria spiraled around it, and it is used for STP production for the journey through the female cervix, uterus, and uterine tubes. The tail, or flagellum, executes the lashing movements which move the psermatocyte.

The quantity and quality of the sperm are the main measurements of semen quality. This is a measure of the ability of the semen to accomplish fertilization, or a measure of the fertility of a man.
