Spermatogenisis

The Life Cycle Of The Sperm
Spermatogenesis is the process of how the sperm forms. First, it will start as spermatogonium and go through interphase where the DNA replication occurs.

Second the new cell, now called the primary spermatocyte, will now go through meiosis I and split for the first time into a diploid cell. When the chromosomes in the primary spermatocyte split, there will be two homologous pairs that share genetic information. Their centromeres do not split, but the homologous pairs split.

After the primary spermatocyte splits, it becomes secondary spermatocytes which are haploids. The secondary spermatocytes split again during the process of meiosis II, but this time the centromeres split, and the genetic information is not exchanged. After the secondary spermatocytes go through the process of meiosis II they become mature sperm.

A mature sperm has four main parts and one main function. The main function of the sperm is to fertilize the ovum to create offspring. The first part of the sperm is the acrosome, its function is to pierce the jelly coat of the ovum. The second part of the sperm is the nucleus, its function is to fertilize the ovum. The third part of the sperm is the mitochondria witch powers the tail by creating energy. The last part of the sperm is the tail which moves the sperm into the woman and to the ovum.
