What will happen to test tube babies in 50 days?
In vitro fertilization (IVF) refers to the process of transplanting the fertilized eggs into the uterus of a woman through in vitro fertilization (assisted reproductive technology) to continue pregnancy and development. The development of IVF is a wonderful process, and each development stage has its own specific changes. This article will elaborate on the changes of IVF in 50 days from four aspects: embryonic development, organ formation, sleep and eating habits, and mobility.
embryonic development
In the 50 day development process of IVF, the embryo has completed several important development stages. In the first few days, the fertilized egg will move in the fallopian tube and then enter the uterus. About 15 days later, the embryo will form three embryonic layers: ectoderm, mesoderm and endoderm.
At this stage, the ectoderm will develop into the placenta, playing the role of providing nutrition and oxygen; Mesoderm can form organs and tissues; Endoderm further differentiates into nervous system and muscle tissue. At this time, the embryo has its own cellular components, and begins to differentiate and develop.
In the next few days, the embryo will become more mature and form basic structures such as head, arms and legs. At this time, the embryo has already possessed the basic shape of the human body and formed the basic contour of the human body.
Organogenesis
After 50 days of IVF, various organs began to form gradually. The heart of the embryo begins to beat around 20 days and continues to improve gradually during development. At 50 days, the heart has formed four atria and four ventricles and started to run.
In addition, lung, liver, kidney, stomach and other organs begin to form at this stage. With the further development of the embryo, these organs will continue to grow and improve.
The process of organ formation is an important milestone in the development of IVF, which marks the further development of the embryo into a complete life.
Sleep and eating habits
During the 50 day development of IVF infants, sleep and eating habits also changed. In the initial stage, IVF babies will have a longer sleep time, about 16-20 hours of sleep every day. As time goes on, the sleep time will gradually decrease. At 50 days, IVF babies usually sleep 12-14 hours a day.
The diet of IVF is also changing gradually. In the first few weeks, breast milk or formula is the main food source. After 50 days, IVF infants gradually began to add complementary foods to meet their nutritional needs.
Changes in sleep and eating habits are crucial to the healthy development of IVF babies. Parents need to make reasonable adjustments and management according to the doctor's suggestions.
Operational capacity
During the 50 day development of IVF infants, their mobility was also gradually improved. In the first few weeks, IVF babies had a small range of motion, mainly lying and lying on their side. Over time, IVF babies began to be able to raise their heads, roll over, and have a certain ability to sit and stand.
At 50 days, IVF babies are usually able to grasp objects independently and have a certain ability of active movement, such as tossing and turning in bed, kicking forward and so on.
The improvement of mobility is crucial to the development of IVF. Parents should provide them with a safe and suitable environment to encourage and support the autonomous movement of IVF infants.
Summary
During the 50 day development of IVF, the embryo will go through two important stages: embryonic development and organ formation. At the same time, the sleeping and eating habits of infants will also change, gradually changing to the adult model. In addition, the mobility of IVF babies is gradually improving, from lying down to grasping objects, and they have a certain degree of autonomous mobility.
The development of test tube babies after 50 days is a complicated and wonderful process, which also brings joy and responsibility to parents. Parents should provide appropriate environment and care according to the suggestions of relevant doctors to promote the healthy growth of IVF.
