Formula for determining gender based on gestational sac size at 9 weeks

The birth of life is always happy. The gestational sac is the initial form of pregnancy, and new life will sprout and develop here. I guess many people have heard of the gestational sac being used to determine the gender of a baby. The gestational sac can be seen in the uterine cavity through ultrasound 35 days after menstruation. So how do we judge? Let’s learn about the formula for calculating the gender of the fetal sac!

The formula for determining the gender of the fetal sac is: if the first data point of the fetal sac is twice the last data point, it is a boy; if there is not much difference, it is a girl. There are two standards for judging the gender of the gestational sac! 1. First of all, the data cannot exceed 8 weeks, 40 days is the best. 2. Then there must be 3 data. Without 3 data, it cannot be identified. Because the fetal sac is cylindrical, each ultrasound technician will take the cross-section in a different direction when doing the B-ultrasound. Some take cross-sections, some take vertical cross-sections. Therefore, it is impossible to tell whether it is a man or a woman by looking at whether the picture is long or round.

For example, the gestational sac is 40*20mm. There is no way to distinguish it at all. On the surface, the two numbers are half the distance, so it should be a boy. But no, because there is no third number. If it is 40*40*20, it is definitely a boy. But if the ultrasound technician does a cross-section, the gestational sac becomes two numbers of 40*40mm, which looks round. Then it is concluded that the gestational sac is round, but how did the child grow out? It seems like an absolute fraud. Therefore, there must be 3 pieces of data. If the gestational sac is an arithmetic progression, such as 40*30*20, then it is a girl. However, if the ultrasound technician takes a 40*20 cross-section, it looks like a boy's data, but a girl grows out, leading to the saying that the gestational sac cannot be used to determine the gender of the baby.

In fact, the term "gestational sac prediction for gender" is not so accurate. Scientifically speaking, the gestational sac varies from person to person, and is largely related to the physical condition of the pregnant mother. In addition, factors that affect the appearance of the gestational sac include pregnancy time, nutrition, embryo implantation site, uterine cavity size, etc.
