The statement that a boy is born in a few months is incorrect and has no scientific basis. The birth of a boy or a girl depends mainly on the sex chromosomes of the fetus, i.e. X and Y chromosomes, and is usually not related to the month. When the sperm and egg meet and combine to form a fertilized egg, the sex of the baby is already decided, and has nothing to do with the month. In human germ cells, there are 46 chromosomes, of which 22 pairs are autosomes and 1 pair is a sex chromosome. The female sex chromosome is XX and the genotype can be expressed as 46, XX; the male sex color is XY and the genotype is 46, XY. The egg contains only one type of sex chromosome, X, while the sperm can contain either X or Y sex chromosomes. So whether a fertilized egg develops into a boy or a girl depends mainly on whether the sperm that combines with the egg is of type Y or X. If the sperm is of type X and the egg is of type Y, the sperm will have the same sex chromosome as the egg. If an X sperm combines with an egg, a girl is born, and if a Y sperm combines with an egg, a boy is born. In this case, the combination of both X and Y sperm with the egg is random, so there is a fifty percent chance of having a boy and a fifty percent chance of having a girl. Therefore, there is no scientific basis for the claim that a boy is born in a few months. It is recommended that both men and women should undergo a medical examination before getting pregnant. Once abnormalities are detected, it is recommended that they should seek timely medical treatment, and under the guidance of the doctor, complete the relevant examinations to clarify the cause of the disease and treat the symptoms.
