What is the transport of sperm?
The path of sperm, in humans and animals, is a short but complex story of the beginnings of life. In addition to the basics of mating, creation and conception, scientists carefully studied precise means of transport of sperm to the best facilitating artificial insemination, infertility treatment and contraception. This includes not only understanding of what happens to sperm before leaving a man, but also after entering a woman.
The general knowledge is that the transport of sperm begins when sperm cells are produced in the male testicles, but this is the extent of many people's knowledge. In each of the testes of the small coil called Siminiferous Tubuly, they produce about 12,000,000,000 sperm for an average mature male each month. Before maturity, these cells are stored just above the tubules in the epididymis, where they remain until maturity.
When the penis is stimulated, the transmission of sperm moves from the epididymis through the vas deferens tube to ejaculation channels. This teKutina contains food for cells in the form of glucose and protection against vaginic acid climate in the form of alkalins. After ejaculation, the seed fluid is powered by a prostate, which adds a strong milk prostate fluid for increased speed when swimming with a vaginal urethra.
sperm transport can take up to 48 hours. This is how long sperm has to find and fertilize eggs inside the uterus before die. According to the Faculty of Medicine of the University of Pennsylvania, only about 200 of the approximately 300 000 000 sperm gets in each ejaculation. Only one - and sometimes several others - will be allowed to enter a new life.
As soon as it is stored at the cervix entrance, the seed fluid begins to release the sperm from its grip. This begins the capacity or final maturation process and hyperactivation. Cells are mixed with acidic cervical mucus that eliminates weak cells and allows strong cells to enter DAleely suppository.
When it arrives in the transport of sperm in the wagon pipes, the uterus actually stores thousands of sperm in suspended fertility until the egg reaches the central part of the fallopian tube, called an amphly Istmic intersection. Most human fertilization takes place here because sperm - coaxial hormonal and thermal pulses - can arrive at an unripe egg or oocyte. Here the eggs of the outer membrane, called Zona Pellucida, allows you to enter one sperm and then lock all the others. Between the egg and the sperm, which has been divided in the next nine months, a unicellular zygot is formed to form descendants.
