What does double gestational sac mean?

What does double gestational sac mean? If the doctor tells you that you have double gestational sacs, then congratulations, it means you are pregnant with twins. Today, when the second child policy is implemented, for many people, being able to have two children at once would be double happiness. Of course, this kind of thing is something you can only encounter by chance, and not everyone is so lucky in life. If you have twin gestational sacs, then prepare in advance.

Double gestational sac means twins. The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, after 35 days of amenorrhea, the gestational sac can be seen in the uterine cavity by B-ultrasound. 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. The gestational sac is the primitive placental tissue, a small embryo wrapped by the amniotic membrane and vascular network. The gestational sac is the initial form of pregnancy. At that time, the fetus has not yet formed, and the fetal heartbeat is already there when the embryonic bud appears. In the second week, the embryo implants in the endometrium. When it develops into the second germ layer, a large cavity called the primary yolk sac appears on the ventral side of the embryonic disc. The yolk sac continues to shrink and degenerate during embryonic development, but the extraembryonic mesoderm on the wall of the yolk sac is the earliest origin of the formation of blood cells, blood vessels and primitive germ cells - the gestational sac, where the fetus will grow in the future.

Since the discovery of the gestational sac has proved that a fetus can survive outside a woman's uterus, it is no longer a dream for a man to become pregnant. However, it goes against the laws of nature, and the medical community is not keen on studying it.

An empty gestational sac means that the embryo has not developed well. There are many reasons for this, such as poor sperm quality and environmental factors that can affect embryonic development. Sometimes an empty gestational sac can also occur if the fertilized egg is late.

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

To determine the gender of the gestational sac means that the gender of the fetus can be analyzed based on the data of the gestational sac on the B-ultrasound data sheet.

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 development of the fetus affected by the pregnant mother's personal circumstances. 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.

However, there is no medical evidence to prove that it is correct to judge the gender of the gestational sac. Gender is determined by genes. Some people say that the gestational sac can accurately predict the gender of a baby. Perhaps it’s just because the probability of male or female gender is 50%, so the probability of guessing correctly is also very high. Therefore, there is no medical basis for determining the gender of a baby based on the gestational sac.

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. Some mothers reviewed the ultrasound data from their pregnancy to verify it. For example, one mother's gestational sac size was 16mm×17mm when she was 8 weeks pregnant, and she gave birth to a little princess. Therefore, it can be seen that the size of the gestational sac cannot indicate the gender of the fetus.
