The size of the gestational sac at 8 weeks determines the gender of the baby

During pregnancy, parents are most concerned about two things: the health of the child and the gender of the child. There are many folk methods and legends for observing the baby's gender. The most common one is B-ultrasound test. There is also a saying that the gender of the baby can be determined by the size of the gestational sac. So, can the 8-week gestational sac be used to determine the gender of the baby?

The gestational sac actually varies from person to person. The "person" here does not refer to fetuses of different genders, but to the pregnant woman herself, or the development of the baby affected by the pregnant mother's own special circumstances. Using B-ultrasound to accurately measure the gestational sac is mainly used to estimate the gestational age. According to the changes in the data, defects in the baby's development can be discovered in time. Generally speaking, a small gestational sac may be due to anxiety, which may cause delayed menstruation, delayed ovulation, and late pregnancy, resulting in a gestational sac that is smaller than the actual number of days of amenorrhea. Therefore, the condition and size of the gestational sac cannot determine whether it is a boy or a girl. If the gestational sac is small, pregnant mothers should pay more attention to it, as it may not be a sign of having a boy or a girl, but a sign of insufficient development of the baby.

How to check the gender of the fetus? B-ultrasound is a common way to check the gender, but it cannot be determined if done too early. Generally, it is necessary to wait until the reproductive organs of the fetus have grown and developed before it can be determined. Therefore, it is more accurate to do it after 20 weeks. However, it is easy to misjudge due to obstruction of the fetus's hands and feet, which is also closely related to the experience of the examining physician. There are many people who make a comeback against the odds, probably eight or nine out of ten can win. It does no harm to pregnant women and fetuses and is inexpensive, but according to regulations, doctors are not allowed to inform the fetus of gender identification.

You can also do amniocentesis or villus biopsy to determine the gender of the baby. The accuracy is very good, close to 100%. Variogenic biopsy to determine the sex of the baby should be done at 10-12 weeks, while amniocentesis can be done at 18-20 weeks. The purpose of obtaining cells from the amniotic fluid of pregnant women to detect the fetus's sex chromosomes is to eliminate the risks of fetal malformations, Down syndrome, etc.
