Throughout history, people have maintained an eternal passion for speculating whether a pregnant woman will give birth to a boy or a girl, which has led to many folk methods circulating on how to calculate whether to give birth to a boy or a girl, including those related to ovulation day. Have you ever heard of having sex with a girl before ovulation day? What do you think? Let's discuss this issue together.
The chance of getting pregnant during sexual intercourse on the day of ovulation may reach 90%. The probability of having sexual intercourse before and after ovulation is high, and it is not related to the gender of the fetus, but to the male sex chromosome. There is no scientific basis for determining when the probability of having a girl in the same room is higher. The probability of having a boy or a girl is generally 50-50. Although an alkaline environment is favorable for sperm survival, the probability of having two types of sperm, X and Y, is 50-50. Women's eggs are X-shaped, with XX giving birth to girls and XY giving birth to boys.
There are two possibilities for the sex chromosomes in sperm, some of which obtain X sex chromosomes during cell division, known as X sperm; Some individuals obtain Y chromosomes, known as Y sperm. At the moment of fertilization of the egg, if egg X encounters Y sperm, the sex chromosomes of the fertilized egg become XY pairs. Due to the presence of testicular determination genes on the Y chromosome, it will be conceived as a male infant, otherwise the opposite is true. The gender of the fetus is determined as early as the moment when the sperm and egg combine to form a fertilized egg, and is not subject to the wishes of the parents, nor is it related to whether they have sexual intercourse on ovulation day.
In this way, there is no scientific basis for determining whether to have a man or a woman during sexual intercourse. It may be that in ancient times, people's observations over a period of time coincidentally matched people's calculations, which gave rise to so many folk methods for calculating gender. We modern people certainly cannot use this to determine the gender of a fetus, so it's okay to adjust it as a joke in our daily lives.
