The semen does three things: 1  Provides a watery environment in which the sperm cells can swim while outside the body.2  Provides nutrients for the sperm cells (fructose, amino acids and vitamin C). 3  Protects the sperm cells by neutralizing acids in the female's sexual tract.uring sexual intercourse, smooth muscles contract and propel mature sperm from the end portions of the epididymis through a long tube called the vas deferens, which is inside the body, just beneath the bladder.
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.
