Development process of test tube baby
IVF refers to the process of transferring the fertilized eggs cultured in the laboratory through in vitro fertilization technology to the mother's uterus to develop into a fetus. The developmental period of IVF can be divided into several key stages.
The first stage is the culture and development of fertilized eggs. When a woman ovulates, doctors will collect mature eggs from her ovaries and combine them with sperm. These fertilized eggs will be cultured in the laboratory for several days until they reach the optimal development state.
The second stage is embryo transfer. The cultured fertilized eggs will be transferred to the uterus of the female, and one or more fertilized eggs will be selected for transplantation. This process is usually carried out after women's ovarian stimulation drug treatment to increase the probability of pregnancy.
The third stage is embryo implantation. Once the fertilized egg is transferred to the uterus, it needs to be implanted and attached to the uterine wall to continue to develop. This process, called implantation, usually occurs about one week after embryo transfer.
Time factors for developing into a healthy baby
The growth rate of test tube babies varies from individual to individual, and it usually takes several weeks to develop into healthy babies.
Combination of sperm and egg
After successful fertilization, it takes about 3 to 5 days for the cultured fertilized eggs to develop into embryos. However, not all fertilized eggs can successfully develop into transplantable embryos. In the laboratory, doctors will observe the development of the fertilized egg and select the healthiest embryo for transplantation.
Embryo transfer and implantation
Once the fertilized egg is transplanted into the uterus, it needs to be implanted and attached to the uterine wall to continue to develop. This process usually occurs about a week after embryo transfer. The embryo will develop a structure called embryo yellow sac, through which it will contact the mother's blood to obtain necessary nutrients and hormones.
Embryonic development and pregnancy confirmation
After embryo transfer, doctors usually conduct blood tests about 10 to 14 days later to confirm whether pregnancy occurs. At this time, the embryo has developed into a multicellular embryo, whose cells differentiate and form different embryonic layers. By measuring the level of hCG (human chorionic gonadotropin) in the body, we can determine whether the pregnancy is successful.
Time Factors of IVF Development
The development time of test tube babies varies from individual to individual. It takes about 3 to 4 months to diagnose pregnancy, and then it takes more time to confirm whether they have developed into healthy babies.
Confirmation of pregnancy
In the early pregnancy, women will have some early pregnancy symptoms, such as breast pain, nausea, vomiting, etc. These symptoms usually appear at about 6 to 8 weeks and gradually disappear in the second trimester of pregnancy.
Further development of the embryo
From the confirmation of pregnancy, the embryo will continue to develop in the uterus. At 7 to 8 weeks, routine B ultrasound can observe the heartbeat of the fetus and further determine whether the pregnancy is developing normally. At this stage, doctors can detect the size and shape of the baby.
Pregnancy examination and prenatal guidance
During pregnancy, pregnant women need to have regular prenatal examinations to ensure the health and development of the fetus. The doctor will carry out detailed examinations, including prenatal ultrasound examination, blood examination and urine examination, and provide appropriate nutrition guidance and lifestyle advice.
summary
The development process of IVF includes several key stages, such as the culture and development of fertilized eggs, embryo transfer and implantation, embryo development and pregnancy confirmation. According to individual differences, it usually takes 3 to 4 months to develop into a healthy baby. Through regular prenatal examination and doctor's guidance, the development process of IVF can be monitored and tutored to ensure the health of mother and baby.
