As the fetus gradually grows up in the mother's womb, the gender of the fetus gradually becomes apparent. Pregnant mothers are particularly curious about whether the baby in their belly is a boy or a girl. There is a test strip circulating online that can determine the gender of a baby. Is the test strip for fetal gender accurate? Let's all learn about it with me.
The principle of urine test strips for detecting fetal gender is to identify the difference in hormones secreted by the fetus in the mother's body. Human chorionic gonadotropin can be detected in urine. The detection principle of this test strip may be to determine the gender of the fetus by detecting the secretion of male hormones contained in HCG. However, due to the extremely subtle difference in hormones secreted by male and female fetuses in the mother's body, coupled with the interference of the mother's own hormones, relying solely on hormones in urine is not enough to determine the gender of the fetus. But HCG can only detect whether the baby's development is normal, and measuring gender through urine is essentially unreasonable. Those who have studied high school biology know that gender determination can only be determined by the sex chromosomes of sperm participating in the acrosome reaction in the mother's body. Even if the father's reproductive cells are examined, fetal gender cannot be detected.
Even if ultrasound is used to determine fetal gender, errors may occur due to factors such as fetal position. At present, there is only one accurate method for determining fetal gender, which is to perform chorionic villus puncture and amniocentesis after more than 4 months of pregnancy. It is to extract fetal villi and amniotic fluid, identify fetal chromosomes, and thus distinguish gender.
From the analysis above, it can be seen that the test strip used to test the gender of the fetus is inaccurate. With the opening of the two child policy, many families hope to have both children, which has led to a trend of online sales of fetal gender test strips. Both male and female babies are unique treasures for expectant mothers. As long as the babies are healthy, it is the greatest happiness for parents.
