Yolk sac method to distinguish the gender of the egg

Yolk sac method to distinguish the gender of the egg

Every pregnant mother is curious about whether the fetus is a boy or a girl. This may not be a concept of male superiority and female inferiority, but knowing the gender of the fetus in advance can enable her to make adequate preparations in a targeted manner. So, can we distinguish between men and women based on the yolk sac? What is the method of distinguishing between men and women based on the yolk sac? Let's discuss it below.

Yolk sac distinguishes male and female methods:

I heard that the size of the yolk sac can distinguish between men and women. Once you understand the basic principles, you can certainly find the answer.

First of all, different DVAs will undoubtedly have their own different shapes. In the early stage of development, the egg cell basically maintains a circular shape. Even after the embryo implants, it basically maintains a circular shape before the embryo develops to 13mm.

Secondly, the gestational sac of XX sex chromosomes is more like a ring, while that of XY is more like a long strip. However, the two sex chromosome test tube embryos were very similar to rings in the early stages, but after exceeding 19mm, the differences were quite large and it was impossible to find exactly the same appearance. Only in the early stage, that is, when the test tube embryo is 13-18mm, the size and shape of the yolk sac are affected by DNA, and the gender can be distinguished based on the size and shape.

However, there will always be deviations in the images presented by B-ultrasound, and it is difficult to accurately distinguish between men and women, so don't trust this method too much.

When does the yolk sac appear:

First of all, we know that the yolk sac is the first substance that can be seen on ultrasound during pregnancy, so it will also appear during your first prenatal check-up. In addition, the yolk sac is the important shipping system between the test tube embryo and the pregnant mother, and is indispensable during the entire pregnancy period.

If the yolk sac is not found during the prenatal check-up, the nutrient transfer between the test tube embryo and the pregnant mother will be interrupted, and it is more likely to cause pregnancy arrest. It is the most basic substance for normal embryonic development.

Under normal circumstances, the yolk sac can be detected at 35 days of pregnancy. However, it also depends on the specific situation. If the expectant mother's menstrual period is delayed, the appearance of the yolk sac will also be delayed.

Knowing when it appears, will expectant mothers feel more at ease? During pregnancy, you must pay more attention to rest and nutrition.
