Maybe what you mean is it's use it is used for movement and it is well developed
The tail of sperm is called flagellus and it also has a centriole in the tail as well. The centriole helps and propels the sperm to swim.
because its got a tail to swim and the egg doesnt well done for getting this right
Well because you haven't developed yet you begin to produce sperm between 12 and 14
Yes, that is actually their intended purpose. Many microbes have flagella to help them move around in their environment. The well known "tail" of a sperm cell is actually a flagella and what the sperm uses to move, or "swim", into the uterus.
Well SPERM?
The spermatozoon is a remarkably complex metabolic, locomotive and genetic machine. It is approximately 60 microns in length and is divided into 3 sections: head, neck and tail. The oval sperm head consists of a nucleus containing the highly compacted DNA, and an acrosome that contains the enzymes required for penetration of the egg shell for fertilization. The neck maintains the connection between the sperm head and tail and consists of the connecting piece and proximal centriole. The tail harbors the midpiece, principle piece and endpiece. The tail midpiece contains the axoneme or engine of the sperm and the mitochondrial sheath, the source of energy for movement. Physiologically, the sperm axoneme is the true motor assembly and requires 200-300 proteins to function. Among these, the microtubules are the best-understood components. Sperm microtubules are arranged in the classic "9+2" pattern of 9 outer doublets encircling an inner central doublet. Defects in the sperm axoneme are well-recognized causes of ciliary dyskinesias that are routinely associated with infertility.
