Baby girl fetal sac

The gestational sac is the initial embryonic tissue, a small test tube embryo encapsulated by the amniotic membrane and vascular network, and is only seen in the early stages of pregnancy. For women with standard menstruation of 28 to 30 days, after 35 days of amenorrhea, the gestational sac can be seen in the uterine cavity by B-ultrasound, even though the fetus has not yet been born.

Gestational sac determines gender

According to folklore, the gender of the fetus can be determined by looking at the appearance of the gestational sac in the B-ultrasound report.

If the length of the gestational sac is more than twice its width and is long and rectangular in shape, it is likely to be a boy.

If the gestational sac is the same length and width, or the distance between them is not far, and it is oval or ring-shaped, it is likely to be a girl.

Can the gestational sac accurately predict the gender of a baby?

Some people use the size and shape of the gestational sac to determine the sex of the fetus. So is the gestational sac accurate in determining the gender of a baby?

Myth: If the gestational sac is long and narrow, then it is likely to be a boy; if the gestational sac is oval or ring-shaped, then it is likely to be a girl.

explain:

The shape of the gestational sac of pregnant women has nothing to do with the gender identification of the fetus. It is determined by many factors such as pregnancy time, nutrition, embryo implantation site, and uterine cavity size.

1. Generally, the gestational sac of a fetus that is growing and developing well is round and flat, but sometimes the gestational sac will be elongated depending on the shape of the uterine cavity. The shape of the fetal sac is actually determined by its supporting force and the flow of amniotic fluid, and it will change its shape autonomously. Therefore, the gestational sac seen may be different depending on the duration of pregnancy.

2. The appearance of the gestational sac also depends on the situation when the pregnant woman is examined. For example, some pregnant women hold their urine for a long time, which causes their uterus to be flattened, and the gestational sac also looks flatter.

3. For some pregnant women, the sperm and egg embryo implantation site is correct, while for others it is a little off, resulting in different shapes of the gestational sac.

4. The position of the B-ultrasound camera is different each time, and the appearance of the fetal sac will be different when observed from different angles.

To sum up the above explanation, we can understand that the shape of the gestational sac cannot determine the gender of the fetus. However, pregnant women should pay attention to observe the shape of the gestational sac to determine whether the fetus is healthy.
