How much sperm live, and how much they stand out with ejaculation

Spermatozoa are male sex cells,which are released during 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 malesex cells largely depends on the conditions in which they are. So, for example, in the open air they live very short - less than a few hours. Many people ask themselves how much the sperm lives 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. The term of 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 section of the female reproductive 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. Moreover, spermatozoa are interesting in that 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.

The most common question is how many days there aresperm, 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, since the chance of fertilizing an 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 that is performed is a spermogram. Perhaps its most important point is the determination of how many sperm are per each ml of seminal fluid.

Despite the fact that life expectancyspermatozoa scientists are still arguing, we can say with confidence that under normal conditions of this period it is quite enough that male reproductive cells fertilize the egg.
