Is the long-awaited birth or undesirable event, that it was better to know as early as possible.So, how many become pregnant after unprotected intercourse?
To understand this, you need to refer to the mechanism of conception in humans.After maturation of the dominant follicle in one of the ovaries release an egg from it.After ovulation, it moves to the uterus by the fallopian tube, leaving a trail of specific substances to the sperm it was easier to detect.Fertilization occurs towards the uterus, and when the merger germ cells depends on the day of the cycle.More precisely determine how many become pregnant after having sex, help information about the lifetime of male and female sex cells.
necessary to take into account that living sperm in the fallopian tubes and uterus to 5 days - those who do not hurt the acidic environment of the vagina and ciliated epithelium pipes.The acidity of the vagina in women (Ph) is 6, and after 2 hours it kills all the male reproductive cells, which continue to remain in it.
In anticipation of ovulation eliminated another obstacle on the way to the uterus: mucous plug covering the cervix under the influence of hormones diluted.The aim of all these stages of selection - give way only the most healthy, fast and sturdy carrier of genetic information.In any case, only one sperm penetrates the egg membrane and the nucleus of the cells of the two merged.When pregnancy occurs after conception?Celled embryo (zygote) is formed in the period 12-24 hours after ovulation, even if the sexual act occurred 3-4 days before.
is noteworthy that if the egg through the shell of a single sperm penetrates, so the fetus is viable.In the first weeks of pregnancy a woman's body regulating system reject such "defective" fetus, a woman may not even know about the failed pregnancy: menstruation come on time or a little later.
If the task in front of a pair of successful conception, the question - how many become pregnant, it is very relevant.After released from the ovary to the egg can be fertilized, important definitions (very high) concentration of live sperm.Lack of concentration is one of the causes of male infertility.Therefore, X must be up to an hour abstinence period of 2-3 days.
Find out how long pregnancy occurs, which precedes the follicular maturation will help the measurement of basal body temperature and ovulation tests.The first method is more laborious and requires a high accuracy.The second is more convenient: the test strip can be dipped in a container of urine at any time.The concentration of luteinizing hormone LH accurately determine the phase of the cycle.12 hours before ovulation concentration of the substance in the body is maximum, clearly indicate that at 2 bars.The surest way to achieve the goal - to make love right after a positive test for LH.
should be understood that although formally a new life is born at the moment of fusion of germ cells, fertilized egg should still have a long way to the uterus.How many pregnancy occurs, which refers to the introduction of the fetus in the uterine cavity?If the fallopian tubes are no obstacles, that is, areas of obstruction, about 10 hours after fusion new cell enters the uterus and try to gain a foothold there.If for some reason the movement slows down to 2-3 days, there is a risk of ectopic pregnancy.Then the fruit is doomed, and there is a threat to the mother's life.
implantation of the ovum is required for its power, because the stocks of the corpus luteum is not enough time.Problems can occur if the endometrium is very thin, and there are scars and fibroids in the uterus.A foreign body, such as a spiral prevents the egg to gain a foothold in the right place.If the woman had no history of curettage and surgical interventions, most of all, the implantation is successful, and chorionic villi vrastut vessels in the endometrium.Now originated life is not in danger, food, and supplies the embryo with oxygen will occur through the maternal organism.
