The size of the gestational sac at 50 days determines the gender of the baby

After pregnancy, a gestational sac will appear first, and then a fetus will be formed after continuous development. The size of the gestational sac is different at different times. The purpose of detecting the size of the gestational sac is mainly to observe the development. National laws do not allow for random checking of the sex of the fetus during pregnancy, so many people will judge the sex of the fetus based on the size of the gestational sac. So, does the size of the gestational sac at 50 days determine the gender of the baby? Let’s take a look below.

When inferring by the size of the gestational sac, some claims require a vaginal ultrasound and the provision of three data. If it is abdominal ultrasound, the accuracy will be reduced. Among the three data, the longest diameter is 13 to 18 mm. This size is not absolute, but the larger the size is from this range, the lower the judgment accuracy will be. If two of the three data are basically equal, and the other data is half of the first two data, then it may be a boy; if the three data are close to an arithmetic progression, or the other data is 0.7 to 2.6 times the first two approximate data, then it may be a girl.

However, it is not entirely correct to judge based solely on the size of the gestational sac. The size of the gestational sac varies from person to person, and the condition of the pregnant woman herself will affect the development of the fetus. Measuring the size of the gestational sac with B-ultrasound is mainly used to estimate the gestational age. Based on the changes in the data, defects in fetal development can be detected in a timely manner. It cannot be used to completely judge men and women.

What is a gestational sac

The fetal sac, also called the gestational sac, is the initial form of the embryo in pregnancy. The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, the gestational sac can be seen in the uterine cavity by B-ultrasound after 35 days of amenorrhea. The gestational sac size comparison table, that is, the size comparison table of the small embryo, can let us see whether the fetus can grow normally. The size of the gestational sac is related to the growth environment of the fetus.

When can the fetal sac be seen?

The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, the gestational sac can be seen in the uterine cavity by B-ultrasound after 35 days of amenorrhea. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus; it is normal for it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.
