Head
With its spheric shape, it consists of a large nucleus, which at the same time contains an acrosome. The nucleus contains the genetic information and 23 chromosomes. It also secretes a hyaluronidase enzyme that destroys the hyaluronic acid of the egg cell to enter into it.
Neck
It contains centrioles (proximal centriole and distal centriole).
Middle-piece
It is a highly important part of a sperm cells because it gives energy to the sperm, thereby allowing it to swim once inside the female reproductive system. It contains spirally arranged mitochondria (see the part colored in orange).
Tail
As one shall see, it is the end part of the sperm, which contains the axial filaments. It helps the sperm to swim in the female genital tract. In fact, it is the part that allows sperm to swim fast enough.

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, stored in the epididymis, and is released from the penis.
