Can a test tube baby be born within 15 days?
Since the advent of IVF technology in the 1970s, significant progress has been made. However, the pregnancy period of IVF is actually the same as that of natural pregnancy, generally about 40 weeks. Therefore, IVF babies cannot be born within 15 days. The following will elaborate on the development of IVF from four aspects: embryo implantation, embryo development, pregnancy process and birth stage.
Embryo implantation
An important step of IVF is to implant the fertilized egg into the mother's uterus. This process is usually carried out on the third to fifth days after fertilization, that is, 15 days after fertilization from the egg. At this time, the embryo has developed to the stage of multicellular clusters. Through assisted reproductive technology, doctors locate the embryo in an appropriate position in the uterus to promote its continued development. However, at this stage, it will take some time for the embryo to fully embed into the endometrium and establish a stable connection.
After embryo implantation, the embryo continues to rely on the nutrients and oxygen provided by the mother for development. They will be connected with the maternal blood circulation through the embryo placenta, so as to obtain the required energy and nutrition. This process takes several days, so it is impossible for IVF to be born within 15 days of fertilization.
embryonic development
The fertilized egg continues to divide and develop in the embryonic stage. About the third week after fertilization, the embryo forms three embryonic layers, namely the ectoderm, mesoderm and endoderm. The ectoderm develops into blastoderm and placenta, the mesoderm forms cartilage, bone and nerve tissue, and the endoderm develops into muscles, organs and digestive system.
In the next few weeks, the organs and tissues of the embryo gradually formed. Their development process needs enough time and nutrients. Therefore, IVF babies cannot be born within 15 days of fertilization, because at this stage they are still in embryonic state and have not yet fully developed into the form of babies.
Pregnancy process
Once the embryo is successfully implanted into the uterus and continues to develop in the uterus, the process of in vitro pregnancy is similar to that of natural pregnancy. Generally speaking, the gestation period is about 40 weeks, which is divided into three stages: early, middle and late.
In the early stage, the pregnancy signs may not be obvious, but the embryo gradually develops into the fetus, and the organs are formed normally. The metaphase is the rapid growth period of the fetus, and the mother can feel the fetal movement. The late stage is the fastest growing stage of the fetus, and the mother may face more discomfort and physical changes.
To sum up, the pregnancy process of IVF requires at least 40 weeks and cannot be completed within 15 days. Embryo implantation and embryo development need enough time to ensure the healthy development of the baby, while the mother also needs to be fully prepared and adapted to the pregnancy process.
Birth stage
The birth process of IVF is the same as that of naturally conceived babies. When the fetus is fully developed and the mother's body is ready, the obstetrician and gynecologist will decide to give birth. Under normal circumstances, obstetricians and gynaecologists will choose the appropriate time and delivery mode to ensure the safe birth of test tube babies.
After a long period of gestation and the support of various medical auxiliary technologies, the birth of IVF is the hope of the family. However, the development of IVF cannot be completed within 15 days. Through the analysis of embryo implantation, embryo development, pregnancy process and birth stage, we can realize that IVF will take longer to be born. Therefore, IVF babies cannot be born within 15 days.
In a word, the development and birth process of IVF requires time and careful preparations. The pregnancy period of IVF is the same as that of natural pregnancy, generally about 40 weeks. Whether it is embryo implantation, embryo development, pregnancy process or birth stage, IVF needs enough time to ensure healthy development. In this process, doctors and families need to work together and look forward to the arrival of the healthy birth of IVF.
