If the pregnancy is planned, then it is sometimes necessary to take into account the slightest nuances. It will not be superfluous to know how many sperm cells live in the uterus and vagina. This is an important indicator. And for those who do not want to have kids for now, it is also not recommended to let such important information pass by themselves. It often happens that the child was conceived during repeated sexual intercourse, when viable spermatozoa remained in the folds and on the head of the penis. The period of their activity is an individual indicator for each man, you can find out by passing an analysis - a spermogram.
Dependence of sperm life span on temperature
The indicator of
how much a sperm cell lives depends on the
ambient temperature. For example, it has been observed that for men working in “hot” workshops in hazardous production, it is often reduced. The optimum temperature for maintaining sperm in activity is 37 degrees. If this figure increases, then the life span of the sperm will decrease. From here we can draw a very interesting and very useful conclusion. If a man wants to become a father in the near future, he should not often visit saunas and baths. But not only high temperature affects how much a sperm cell lives. Its low indicators completely immobilize male tadpoles, but they retain their viability. This makes it possible to freeze the seed in special storages and use it in the future for
artificial insemination.How many sperm live in the vagina?
It is known that an egg lives no more than 24 hours. But it is not known exactly how much sperm can survive. Too many factors depend on this indicator. For example, if a woman has an inflammatory process, then they quickly lose their activity. Also, the quality of sperm itself plays an important role. The genital tract of a woman significantly limits the period of life of sperm. It is inherent in nature itself. The woman’s vagina has a slightly acidic environment, but sperm, on the contrary, is alkaline. Accordingly, the weakest spermatozoa die first only for this reason. Only persistent can reach the egg. This is a natural mechanism for selecting only high-quality genetic material. In general, given all the factors, you can approximately answer the question of how much the sperm cell lives in the vagina. This period is from 2 to 7 days.
Sperm in the environment
In the vagina, semen remains active for a long time. Fertilization can occur on the 5th day after sexual intercourse. But in the environment, things are different. How many sperm live in air? Just a few hours. But that is why caution must be exercised. If a woman does not plan a pregnancy, it is recommended not to start a second sexual intercourse without a hygienic procedure for a man. He must carefully wash away all sperm from the penis. If this is not done, then it is quite possible that the preserved sperm penetrate the vagina, and then into the uterus and
fertilize the egg. Such cases, although rare, but still happen.
