How much sperm lives, and how much they stand out in ejaculation

Spermatozoa are male reproductive cells that are secreted by ejaculation (ejaculation). They are produced in testicles (testicles). As a result of this process a man every minute accumulates from 50 000 to 100 000 spermatozoa. Thus, from 72,000,000 to 164,000,000 germ cells are produced daily in testicles. At the same time, many are worried about the question of how much the sperm lives, and how many of them normally should be allocated.

In fact, the life expectancy of male sex cells largely depends on the conditions in which they find themselves. So, for example, in the open air they live very short - less than a few hours. Many are wondering about how much sperm live in the vagina. To date, it is reliably known that these cells can not remain viable for a long time in the acidic environment that is observed in the vagina. Their life here does not exceed that which can be seen in the open air. It is worthwhile to understand correctly that such mobile cells leave the initial part of the female genital tract very quickly. The speed of movement of spermatozoa is about 3 mm per hour. Then they move to the cervix. Alkaline medium is already observed here. About how much the sperm lives in such conditions, many scientists argue. Despite the existing disagreements, it is safe to say that in the cervix, male sex 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, spermatozoa are interesting because their features allow them to participate in the birth of a new organism only to the "qualitative" one. The fact is that too slow male sex cells either die still in the vagina, or simply do not keep up with their more agile counterparts. Naturally, all the "defective" spermatozoa are also eliminated in the process of competition.

Most often, the question of how many days a sperm lives, those who want to have a baby are asked. It is worth noting that, despite the existence of certain frames (2-7 days), for the reproductive cells of each male this term is individual. In many respects it depends on how "quality" he has sperm. The fact is that the sex cells themselves constitute only a small part of it (about 3%). All the rest is a nutritious secret, due to which the life span of spermatozoa considerably increases. In addition, the total amount of sperm and sex cells in it is quite important. To date, the norm is considered if at least 2-3 ml of sperm are released during ejaculation. The content of spermatozoa in it should be at least 20 000 000 per 1 ml. In the event that there are fewer, it practically does not matter how much the sperm lives, because the chance of fertilization of the egg is extremely low. The importance of this indicator is confirmed by the fact that if a couple does not manage to have children, then one of the first tests to be performed is a spermogram. Perhaps its most important point is the determination of how many spermatozoa are per each ml of seminal fluid.

Despite the fact that scientists still argue about the life span of spermatozoa, it can be said with certainty that under normal conditions of this period it is quite enough that male reproductive cells fertilize the egg.
