Timeline and milestones of IVF development
IVF, also known as in vitro fertilization (IVF), is an assisted reproductive technology that helps couples who cannot conceive naturally realize their dreams of childbirth. The development timeline and milestones of IVF are instructive references for couples to understand the development and growth of children at different stages.
Embryonic development stage
Test tube babies need to go through a series of embryonic development stages before birth. These stages include: pre transplant culture, embryo transfer, implantation and embryo development. Culture before transplantation refers to cultivating the fertilized eggs to the best development stage, which usually takes 3-5 days. Embryo transfer is the implantation of an embryo into the mother's body for further development. Implantation refers to the attachment and development of the embryo in the uterus, which usually occurs 5-10 days after transplantation. The embryonic development stage means that the embryo gradually develops into an embryo in the mother.
The timeline and milestones of embryonic development are:
Week 1: The fertilized egg moves into the uterus in the fallopian tube.
The second week: The fertilized egg is implanted in the uterus and begins to develop into an embryo.
Week 3: The cells inside the embryo began to differentiate into different tissues and organs.
Fourth week: The embryo began to have an obvious structure, and the fetal heartbeat could be detected by ultrasound.
Week 5: The basic structure of the head, upper limbs and lower limbs began to form.
Week 6: The outline of eyes, nose and mouth begins to appear.
Week 7: The embryo began to have fingers and toes, and began to move.
Fetal development stage
After the embryonic development stage, the embryo gradually develops into a fetus. The fetal development stage is a very critical period, including the formation of organs and systems as well as the refinement and maturity of various parts of the body.
The timeline and milestones of fetal development are:
Week 8: The fetal head becomes more normal, and the limbs begin to grow longer.
Week 9: The fetus began to have facial features and hair began to grow.
Week 10: The fetal movement gradually increases, and can be observed by ultrasound.
Week 11: The muscular and skeletal systems of the fetus begin to develop.
Week 12: The weight and size of the fetus gradually increase, and the sex of the fetus can also be detected by ultrasound.
Week 13: The fetal skin begins to form and the fingernails begin to grow.
Pregnancy milestones
After the successful transplantation of IVF, the mother underwent a series of changes and development. Understanding these pregnancy milestones can help couples anticipate and understand maternal changes.
The timeline and milestones of pregnancy milestones are:
Week 12: The embryo develops into a fetus, and the pregnancy enters the second trimester.
Week 20: The fetal movement becomes more frequent and can be felt.
Week 24: The hearing of the fetus begins to develop, and external sounds can be heard.
Week 28: The eyes of the fetus begin to open and can respond to changes in light.
Week 32: The growth rate of the fetus is accelerated, and the hair and nails of the fetus continue to grow.
summary
The development timeline and milestones of IVF provide guidance for couples to understand their children's development and growth at different stages. From the embryonic development stage to the fetal development stage and then to the pregnancy milestone, the development of each stage is a miracle, representing the magnificent process of human life. This timeline and milestone not only provide hope and expectation for couples, but also help them better understand the development process of embryos and fetuses.
