There is no scientific basis for women to use morning urine to put salt into their baby’s sex during pregnancy. There is no need for pregnant women to struggle with such details during pregnancy. In fact, the baby’s sex is determined by the father’s male sperm. If the excellent chromosome issued by the father is X chromosome, then the baby is a girl. If the chromosome provided by the father is Y chromosome, it means the baby is a boy at the moment.
From a theoretical point of view, the probability of X chromosome and Y chromosome formation is 1go 2, so it is mainly decided by the father to conceive a boy and a girl, and there is no theoretical basis for using morning urine and salt to determine sex in the morning.
According to regulations, parents can not identify Darling’s gender during pregnancy, and some patients may use ultrasound to identify the sex of the baby, usually after three months to determine.
Although passing the ultrasound examination can not be thorough, the accuracy cannot reach 100%, but for many parents, they are particularly curious about the gender of the baby in life.
Some parents will send their baby’s blood directly to Hong Kong, or elsewhere, through a blood test, which can usually determine the baby’s gender.
