Fertilization is a miracle of the birth of a new life inside the womb of a woman. The phenomenon, which for hundreds of years worries doctors, parents and continues to amaze all of humanity. Every woman who plans to become pregnant, is interested in the question: "How quickly does fertilization take place?". There is no unambiguous answer to this question, as fertilization occurs because of rather complex processes in the woman's body. However, you can determine the most probable days for conception.
How long does it take to fertilize?
Approximately once a month during the ovulation period from the right or left ovary of the woman one egg leaves (less often two). It is proved that the egg can live 12-36 hours, and sometimes its life does not exceed 6 hours. If fertilization does not occur in this period, the egg leaves with the onset of regular menstruation. In most women, under the condition of a regular cycle, ovulation occurs approximately in the middle of the cycle. However, there are cycles when ovulation is absent. Normally, a healthy woman can have up to two ovulations per year. Also, it is possible that there are two ovulations per cycle.
Spermatozoa live much longer than the ovum. Their life span lasts about a week. Therefore, for fertilization to occur, you need to have sexual contact a few days before ovulation or on the day of ovulation.
After what time does the fertilization take place after sexual intercourse?
If we connect the vitality of an ovum 12 hours and sperm 7 days, then the most probable days for conception are 5-7 days before ovulation and 1 day after. Suppose that you had unprotected sex 6 days before ovulation, then fertilization can occur in 6 days, after the release of the egg from the ovary. Direct fertilization occurs on the day of ovulation, or rather, a few hours after it. If you count the days in a regular cycle, then fertilization takes place on the 6-17 day of the cycle.
Count on safe sex is not worth it. After all, a woman who irregularly has sex, ovulation can occur immediately after intercourse, regardless of the day of the cycle. That is, it is an accidental or rare sexual intercourse that can provoke the onset of ovulation.
Fertility itself can not be considered a pregnant pregnancy. After fertilization, the oocyte must enter the uterus through uterine tubes and be implanted in its wall. On that it takes about another week.
Fertilization is so individual that even physicians never put the exact date of conception, but conduct a pregnancy report from the day of the last menstruation.
