A married couple expecting the birth of a baby, dreams only of that their child was healthy. But, nevertheless, they do not abandon attempts to use all possible methods of determining the sex of the child. They include: calculation by the date of ovulation, by the time of blood renewal, by the time of conception and by preference in nutrition. We will get acquainted with the calendar of ovulation, and how to calculate the sex of the child.
Prognosis of a child's sex by the date of ovulation
Calculate the ovulation of the child's sex can be easily enough if you know the physiological features of sperm - how much does a sperm that contains in its chromosomal set X or Y chromosome, which determines the sex of the child. So, the egg contains only the X-chromosome, and merging with a sperm with an identical sex chromosome, it will form a female fetus. Accordingly, when the egg is fused with the Y-chromosome, a male fetus will form.
Spermatozoa with an X-chromosome are inactive and have higher viability. So, they are able to live in the fallopian tube up to 7 days in anticipation of fertilization. Y-spermatozoies, on the contrary, have high mobility and low viability (in alkaline vaginal secret they can survive up to 2 days before ovulation).
Therefore, if conception occurs after ovulation, then the sex of the child is most likely to be male. And if unprotected sexual intercourse occurred more than 4-5 days before ovulation, then the spermatozoids will die by the time of ovulation, and fertilization will occur as an X-spermatozoon, which explains the conception of the girl.
Define ovulation to calculate the sex of the unborn child, in two ways: by measuring basal temperature (on the day of ovulation, the temperature will rise by 0.4-0.6 degrees) or using special tests for ovulation .
Ovulation and a calculator for determining the sex of a child
Another way to determine the conception of a boy or girl by the date of ovulation is the table that determines the sex of the baby by the month of fertilization and the age of the mother.
But you can try to calculate the sex of the child using the online calculator. To do this, enter the number of the first day of the month, the duration of menstrual bleeding, and include the calculation of the intended sex of the baby. How much the correct result of such a calculator can not be judged reliably.
So, you got acquainted with the calendar of ovulation and methods of determining the sex of the child, but do not forget that none of these methods does not give a 100% result. And the sex of your unborn child is more reliable during the second planned ultrasound study.
