The sperm cells are produced in the testicles. These are located outside the body, since the body temperature is too high, for sperm cells. The sperm that comes out, consists largely of fluid. Only 1 to 3 percent of the semen consisting of spermatozoa.

Spermatozo

A sperm is called spermatozo. An easy to remember name, there is indeed the word sperm. A sperm is a male gamete. The sperm cells are made in the testicles. Along with the seed liquid, they form the seed. This is known by most of the sperm.

Sperm production

The sperm cells are produced in the testicles. These are located outside the body, since the body temperature is too high, for sperm cells. Because the testicles hang on the outside of the body, the temperature is slightly lower, and can survive the sperm cells. The temperature in the testicles is 35 degrees, which is two degrees lower than body temperature. When the sperm cells are ready, they go to the epididymis. The storage of the sperm cells takes place in the last part of the vas deferens. If the sperm are ready to "leave", they are at an ejaculation through the urethra pushed outward. It takes about 65 days for a sperm is all set for the trip.
The sperm, the liquid is added only on the way to the outside. This is done via seminal fluid through the vesicles and prostate.

Sperm

The sperm that comes out, consists largely of fluid. Only 1 to 3 percent of the semen consisting of spermatozoa. Sperm is so freshly prepared. Sperm cells that remain behind during ejaculation, are degraded after about a month and removed by the body. These are absorbed into the blood.
Ejaculation comes about because there smooth muscle in the wall of the epididymis strokes together. First, all squeezed into the urethra, and then pulling the muscles of the pelvic floor together and are sperm cells and sperm pressed out. The nocturnal emission, which is involuntarily is called pollution or wet dream.

The sperm

The sperm cell is made up of a head, a middle part and a tail. The header contains the chromosomes, that is the hereditary material. The head is thus an important part of the spermatozoon. The tail of the sperm used to propel themselves with. Without the tail, the sperm will never be able to reach the egg. The tail of the sperm will only move when in contact with d seminal fluid, semen. Without this fluid, the sperm will therefore still be immobile.
In the epididymis, where sperm are stored, it is not a swarm of sperm, as one might expect. When the sperm in an ejaculation outside are gestuwt and the sperm is added to it, the tails come alive and sway back and forth. In this way, the start swimming sperm towards the egg.

The journey

Arrived in the vagina, the sperm swim frantically. The major part dies but also already before it has reached the cervix. Some got into the uterine cavity. From there, the journey continues on two directions: the left ovary and right fallopian tube. The sperms take any oviduct, hoping that this is the right one. Eventually, only one sperm will reach the egg and penetrate it. The remaining millions of sperms did not make it.
