What is the reason for the enlarged gestational sac?

It is generally believed that a round and flat gestational sac is well developed, which can indirectly indicate that the fetus is in good health. Of course, this is not absolute. Factors such as the amniotic fluid content, the tension of the gestational sac, and the shape of the uterine cavity will also affect the gestational sac. There is a popular belief that if the gestational sac is larger, it means the baby is a boy. However, this belief is untenable from a medical point of view. This is because the size of the gestational sac is related to various factors.

Factors that affect the size and shape of the gestational sac

1. Generally, a well-developed gestational sac is round and flat, but sometimes the gestational sac will become longer with the shape of the uterine cavity. The shape of the gestational sac is actually determined by its tension and the amount of amniotic fluid it contains, and it will change its shape on its own. Therefore, the gestational sac you see may be different depending on the number of days of pregnancy.

2. The shape of the gestational sac also depends on the condition of the pregnant woman during the examination. For example, some pregnant women hold their urine for a long time, which causes their uterus to be flattened, and the shape of the gestational sac also looks flatter.

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

4. The direction of the B-ultrasound probe is different each time, and the shape of the gestational sac is different when viewed from different angles.

Is a large gestational sac usually a sign of a boy?

In fact, the size of the gestational sac varies from person to person. The "person" here does not refer to babies of different genders, but to the pregnant woman herself, or the fetal development affected by the pregnant mother's personal circumstances. Moreover, the shape of the gestational sac is determined by its tension and the space it can expand. If the mother's uterus has a relatively standard shape, the gestational sac will be round or oval in shape after implantation. If the mother's uterus is not standard or there are fibroids in the uterus, the shape of the gestational sac will change after implantation. Therefore, the size and shape of the gestational sac have nothing to do with the sex of the fetus. There is no scientific basis for the belief that a larger gestational sac means a boy.

The size and shape of the gestational sac cannot be used as a basis for determining the sex of the fetus, but it can be used to determine whether the fetus is developing healthily. Therefore, expectant mothers should regularly observe the shape of their gestational sac through B-ultrasound examinations. If any abnormalities are found, they must go to the hospital immediately for treatment.
