A sperm cell consist of two parts, the head and the tail. The overall structure of the sperm, makes it perfectly designed to carry-out its function. The primary function of sperm is to pass on the necessary biological information required to produce a new organism.In humans and most living things, the data that makes an organism what it is, is contained in a tiny molecule called DNA. DNA is basically a recipe book used to make you, well, you.emember, we said that DNA is like a recipe book that contains all of the information that makes the organism who and what it is. Half of the biological information contained in the DNA is packaged in each of the male's sperm cells. The egg cell is packaged in a very similar manner.
Spermatogeneis is the process of sperm production and involves several steps that leads to the differentiation of cells into functioning sperm cells (spermatozoa). The process occurs in the seminiferous tubules of the testes (testicles). Sperm should be differentiated from the semen which is ejaculated with sexual intercourse. Semen is composed of sperm with fluid from the vas deferens, seminal vesicles, prostate gland, and other accessory glands. Sperm Production in the Testes Where does spermatogenesis occur? The production of sperm is a multi-step process that occurs within the seminiferous tubules which are long hollow coiled tubes in the testes. There are close to 1,000 such tubules measuring some one and a half meters in each testis. The walls of these tubules have sperm in different stages of differentiation, Sertoli cells and interstitial cells.
