Endometrium and gestational sac pattern

The uterine wall is a protective membrane inside a woman's uterus. This membrane can change under the action of female hormones and estrogen, thereby producing menstruation. This is also the area where the test tube embryo develops and grows. The gestational sac is the initial form of pregnancy and can usually only be seen in the early stages of pregnancy. It cannot be seen in the second half of pregnancy. So, what is the difference between the uterine wall and the gestational sac?

The difference between the uterine wall and the fetal sac is that the uterine wall is the protective membrane of the uterine lining. Menstruation will occur after this layer of endometrium falls off. All women of childbearing age have a uterine wall. The gestational sac is the initial embryonic tissue that is produced after a woman becomes pregnant. If you look at it from the appearance alone, the gestational sac is generally round, while the uterine wall is irregular and relatively thin.

The size of the gestational sac will change as the fetus grows. Women can check the size of the gestational sac through B-ultrasound examination. Generally, under B-ultrasound examination, not only the gestational sac can be clearly seen, but also the fetal heartbeat and fetal heartbeat can be seen.

The thickness of the uterine wall will also change. At different stages, the thickness of the uterine wall will soften or thicken. The uterine wall is affected by estrogen. When a woman's body metabolizes too much estrogen, the thickness of the endometrium will increase. When estrogen is metabolized too little, the uterine wall will become soft.

Can the fetal sac accurately determine the gender?

Some people think that in the early stages of pregnancy, the gender of the fetus can be determined based on the appearance and size of the gestational sac in the 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. In fact, 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.

In general, we can understand that the appearance 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.
