Sperm

So we know about the male reproductive organ and how a sperm is created, so how does it reach the female? Well, firstly, let us look at how the sperm looks like.

So let's begin, the main function of the sperm is to carry the 18,000 male genes to the female’s egg. These genes represent the male's contribution to the DNA make-up of the hoped-for baby. The sperms that have been stored will be ejaculated through semen through the penis and into the vulva when the male is having sex. Then sperms compete to be the first that reaches the egg, so how do they reach it?
They reach it through features in their structure, namely the acrosome, the energy source and the tail. The acrosome also has a surface feature in its membrane which allows it to burrow through the shell of the woman's egg. Using the enzymes that are built into its surface, the sperm cell digests its way through the outer eggshell called the zona pellucida. The sperm cell is then able to enter into the main part of the egg, the ooplasm, achieving successful fertilization.
The second component of the sperm cell is the energy source, its sole purpose is to convert nutrients into energy. Without this, the propulsion system would not have the energy to take the cell up the female genital track.
The third and final component of the sperm cell is the propulsion system. It is the whip-like structure of the sperm tail. It serves the important function of propelling the sperm cell forward with a snake-like motion. It is critical that sperm move forward and not laterally or in circles. The failure of sperm to move forward is described as an abnormality of sperm motility.
