How is IVF made?
IVF is a kind of assisted reproductive technology, which can help couples who are difficult to conceive naturally to achieve their reproductive aspirations. The specific process of IVF will be introduced in detail from four aspects.
Embryo culture and selection
The first step of IVF is embryo culture and selection. In the laboratory of the hospital, doctors will put mature eggs and sperm together for fertilization to form a fertilized egg. After that, the fertilized egg will continue to grow and form an embryo. In the process of embryo development, doctors will conduct embryo evaluation, including observing the development of embryonic cells and detecting gene abnormalities. Through evaluation, doctors can select the healthiest embryo and improve the pregnancy success rate.
In some hospitals, specific genetic screening can also be carried out, such as PGD (Preimplantation Genetic Diagnosis) and PGS (Preimplantation Genetic Screening). PGD can screen genetic diseases by detecting the genetic information of embryos, and select healthy embryos for couples. PGS can screen for chromosomal abnormalities in embryos and reduce the risk of miscarriage and abnormal birth caused by chromosomal abnormalities.
embryo transfer
After embryo culture and selection, the doctor will choose the most suitable time to transfer healthy embryos to the mother's uterus. This process is usually simple and painless, similar to intrauterine angiography. Use a catheter to carefully place the embryo in the uterus to help the embryo continue to develop in the mother's body.
Generally, doctors will transfer embryos when they reach the blastocyst stage (about 3-5 days). At this time, the embryo has developed into a mass of cells with the ability of self attachment and embedding in the uterine wall. Choosing the best embryo transfer time can improve the pregnancy success rate.
Pregnancy monitoring
After successful embryo transfer, couples need pregnancy monitoring. Doctors will regularly check the levels of progesterone and β - HCG in the blood of pregnant women to confirm whether they are successfully embedded in the uterus, and monitor the development of embryos. In addition, ultrasonic examination will be carried out to observe the growth and development of embryos and fetuses and ensure that there are no complications.
If the pregnancy is normal, the pregnant woman will continue to receive prenatal care, conduct regular prenatal examination, and adjust diet and lifestyle according to the doctor's recommendations to ensure the healthy development of the embryo and fetus.
Baby birth
After a long wait and effort, IVF was finally born. There is no difference between the birth mode of a baby and that of a naturally conceived baby, which is completed by natural childbirth or caesarean section. Then, the newborn will receive a series of early pediatric care, including physical examination and vaccination, to ensure healthy growth.
summary
Through embryo culture and selection, embryo transfer, pregnancy monitoring and the final birth of a baby, couples can achieve their reproductive aspirations through IVF technology. This process needs the guidance and supervision of professional doctors to ensure the safety of pregnancy and the health of embryos. IVF technology provides a feasible choice for couples who have difficulty in natural pregnancy, and allows more people to become qualified parents.
