Sperm are male sex cells that are secreted by ejaculation (ejaculation). They are produced in testicles (testicles). As a result of this process, between 50,000 and 100,000 spermatozoa accumulate in a man every minute. Thus, from 72,000,000 to 164,000,000 germ cells are produced daily in testicles. At the same time, the question of how many sperm live and how many of them should normally be excreted is very worrying.
In fact, the life expectancy of male germ cells largely depends on the conditions in which they find themselves. So, for example, in the open air they live very briefly - less than a few hours. Many people wonder how much sperm lives in the vagina. To date, the fact that these cells are not able to maintain viability in an acidic environment, which is observed in the vagina, is reliably known. Their life here does not exceed that which can be seen in the open air. It should be correctly understood that such motile cells quickly enough leave the initial section of the female genital tract. The speed of the sperm is approximately 3 mm per hour. Then they move to the cervix. An alkaline environment is already observed here. Many scientists argue about how much sperm lives in such conditions. Despite the existing disagreements, it is safe to say that in the cervix, male reproductive cells retain their viability for 2 to 7 days (usually 3-5 days). All this time, the egg can be fertilized by one of them. At the same time, sperm cells are interesting in that their features allow only the most “high-quality” of them to participate in the nucleation of a new organism. The fact is that too slow male reproductive cells either die even in the vagina, or simply do not keep up with their more agile counterparts. Naturally, all “defective” sperm cells are also eliminated in the process of competition.
Most often, the question of how many days the sperm lives is asked by those who want to have a baby. It is worth noting that despite the presence of a certain framework (2-7 days), for the germ cells of each man, this period is individual. This largely depends on how "quality" he has sperm. The fact is that the germ cells themselves make up only a small part of it (about 3%). Everything else is a nutritious secret, due to which the sperm life span is significantly increased. In addition, the total number of sperm and germ cells in it is quite important. Today, it is considered the norm if at least 2-3 ml of sperm is secreted during ejaculation. The content of sperm in it should be at least 20 million per 1 ml. In the event that there are fewer of them, it practically does not matter how much the sperm lives, since the chance of fertilizing an egg is extremely low. The importance of this indicator is confirmed by the fact that if a couple cannot get children, then one of the first analyzes that is carried out is a spermogram. Perhaps its most important point is to determine how many sperm cells are present for each ml of seminal fluid.
Despite the fact that scientists are still arguing about the life expectancy of sperm , it is safe to say that under normal conditions this term is quite enough for male reproductive cells to fertilize an egg.
