What are the most accurate ways to check whether you are pregnant or not?
The scientific method of pregnancy test for male and female is a very important thing for many expectant parents. Because having a boy or girl is of great significance to every family. In this article, we will introduce in detail the highly accurate method of pregnancy gender detection from four aspects to help expectant parents better predict the gender of their newborn.
Use pregnant women’s B-ultrasound to determine fetal gender
Ultrasound during pregnancy is one of the most common ways to identify gender. The most accurate time to determine gender is usually after 20 weeks of pregnancy. At this time, the gender of the fetus is already very clear. However, in order to determine the gender of the fetus, you must first ensure that a B-ultrasound has been successfully performed during this period of pregnancy. In addition, factors such as the pregnant woman\’s body shape and fetal sac will also affect the display effect of B-ultrasound.
Pregnancy test tool to check male and female
In addition to the B-ultrasound method, some pregnant women\’s tools based on pregnancy test cards or urine can also be used to determine the gender of the fetus. The main basis for the effectiveness of these testing tools is pregnancy hormones. Generally speaking, progesterone levels are higher in pregnant women during the first trimester. If these tools are used, the gender of the baby can be predicted early in pregnancy based on the timing and intensity of reactions.
However, due to certain errors in pregnancy test cards and urine, the gender predicted using these tools is for reference only.
Genetic testing can solve the mystery
In addition to traditional B-ultrasound and pregnancy tests, genetic testing can also be used to determine the gender of the fetus. This is a very high-tech method. By collecting samples from pregnant women\’s blood or mother\’s saliva, analysis covering the entire genome can be performed. These data are compared with the reference genome of the baby\’s father to predict the baby\’s gender.
At the same time, genetic testing also has the advantage of filtering out chromosomal abnormalities during pregnancy.
PGD technology in artificial assisted reproduction
For couples who want to know the gender of their fetus, gender selection technology in artificial assisted reproduction is also a good choice. Among them, PGD technology is more popular. Before embryo culture, genetic diagnosis is performed by removing 1-2 cells, and gender selection is performed to confirm whether the embryo is male or female. The sex-determined embryo is then implanted into the mother in order to achieve a successful birth.
In general, the four methods of pregnancy detection, including B-ultrasound, pregnancy test kit, genetic testing and PGD technology in artificial assisted reproduction, are very accurate. Through these methods, expectant parents can always know the gender of their baby. Of course, each method has its advantages and disadvantages. If you want to know more detailed information, you can consult relevant professional doctors to avoid errors and troubles when choosing a method to check whether you are pregnant or not.
