The human body is a miraculous mechanism. The process of conception and development of the embryo within a woman, even for the “smartest” of this world, remains an unsolved miracle to the end. The birth of a child becomes possible only thanks to amazing “coincidences” and incredible metamorphoses occurring in the secret corners of the female body. How many sperm live and how does the egg fertilize? Incredibly interconnected questions, the answers to which you will find in the article presented to your attention.
Not so simple really ...
Female “secrets” originate in deeply hidden chromosomes that have an X-shaped structure. The body of the expectant mother reproduces the egg every 28 days, which is the result of the cyclic period of the menopause. The stock of germ cells in representatives of the so-called “weaker sex” is limited by a varying number: from 250 to 450 thousand. The life span of an egg depends on many factors. The most important condition for a favorable gametic intercourse of two cells is a certain predisposition of the woman’s body to the moment of conception and, as a result, the ability to bear the fetus and the mutual desire of the couple. The answer to the question “How many sperm live?” can express the competence of the “second half” to play a decisive role, so that the fertilization process becomes possible. Only thanks to this fundamental fact the vital activity of the egg will be justified. Let's go on a short trip with you and try to answer the question, how long do sperm cells live, and also trace important points that will result in an emerging life.
Surprise has no limits
So, after a woman’s reproductive cell has matured and is ready to leave the ovary in order to travel in a certain direction, to the uterus, male sperm rush towards. By the way, the number of “conquerors” is approximately 200-250 million units. Of course, such a huge number is predetermined by a number of difficulties in achieving the goal:
- First, the acidic environment of the vagina and 85% of inferior spermatozoa of the total number of germ cells produced by a man become the most significant factor that impedes the “desired” meeting of the two fundamental foundations of life.
- Secondly, taking into account the fact how many sperm live in a foreign environment (the insecurity of the partner's sex cells is a proven evidence), only 1% of the hardiest of the seed of the husband reaches the cervix.
- Thirdly, “climbing” the chemical ladder, consisting of mucus, diluted with hormones, and leading into the narrow passage of the cervix, is not so easy.
- Fourth, the immune system of a woman, for whom sperm are nothing more than invaders, begins to systematically destroy the male sex cells. White blood cells are incredibly adroit “hunters.”
Scientifically proven fact
How many sperm live, which nevertheless reached the fallopian tube? There are very few such “zingerbirds”. Only 20 or more are awarded a “warm welcome”. And only one of them will complete the "mission" to the end. Usually sperm spend over two hours to overcome such a difficult area. It should be noted that the life cycle of male germ cells remaining in the vaginal environment is limited to a maximum of twelve hours, after which they die. "Lucky" are able to live actively for several days. Medical science knows how many sperm live in the uterus - most often from 3 to 5 days. Needless to say, this time is enough to fertilize an egg and give life to a new member of the human race.
Finally
As you yourself were able to make sure to merge together and become a man, two heterosexual cells have to overcome incredibly complex biological barriers, thanks to which the offspring will inherit from their parents the best and most adapted to life.
