Developmental changes of test tube infants on the 10th day

IVF is an embryo transferred into the mother's body after fertilization and culture in the laboratory through assisted reproductive technology. In the process of IVF development, every day is important, and every day will bring new changes. On the 10th day of IVF, the embryo has developed to a certain extent, and some important changes begin to occur.

Intraembryonic development

On the 10th day of IVF, the development changes in the embryo were very significant. The embryo has differentiated into the endoderm, ectoderm and mesoderm. The endoderm will develop into the internal organs of the organism, the ectoderm will form the skin and nervous system, and the mesoderm will develop into the muscle, bone and circulatory system. In addition, embryonic limb buds have also begun to form, and the foundation of future fingers and toes has also been formed.

At this time, the embryo does not have obvious facial features, but has begun to develop eyes and mouth. The eyes are part of the embryonic brain, while the mouth develops to further absorb nutrients and oxygen.

In addition, at this stage, the blood circulation system of the embryo has also begun to form, and the heart of the embryo begins to beat and deliver oxygen and nutrients to the body tissues.

Changes within the parent

In addition to the development changes in the embryo, the 10th day of IVF may also cause some changes in the mother. First of all, the mother may feel the swelling pain and increased sensitivity of the breast, which is due to the hormonal changes caused by pregnancy.

In addition, some women may have slight vaginal bleeding in the early stage of IVF, which is caused by the implantation of embryos into the uterine wall. This kind of bleeding is generally normal, but if the amount of bleeding is excessive or accompanied by other uncomfortable symptoms, you should consult a doctor in time.

In addition, the early pregnancy of IVF will lead to some pregnancy reactions, such as fatigue, lethargy, nausea, vomiting and appetite change. These reactions are caused by the changes of hormone levels and the increase of metabolic rate in the body.

Detection and observation

On the 10th day of IVF, doctors usually carry out some necessary tests and observations. The first is blood and urine tests to ensure general health during pregnancy and to eliminate other potential problems. In addition, the doctor may also conduct ultrasonic examination to determine the development of the embryo, the heartbeat of the fetal heart and whether the embryo is normally implanted in the uterine wall.

Summary

The 10th day of IVF is the stage of significant changes in embryonic development. At this stage, the embryo has formed the endoderm, ectoderm and mesoderm, and began to develop eyes and mouth. Embryo limb buds and blood circulation system also began to form. At the same time, the mother may have breast pain, vaginal bleeding and early pregnancy reactions and other changes. Finally, the doctor will carry out a series of tests and observations to ensure the normal progress of the pregnancy process.
