Operation mode of IVF
IVF is an assisted reproductive technology, which enables couples who cannot conceive naturally to realize their reproductive dreams through in vitro fertilization. The specific operation methods of IVF will be introduced in detail from four aspects: egg retrieval, in vitro fertilization, embryo transfer and pregnancy monitoring.
1. Take eggs
Fetching eggs is the first step in the process of IVF, aiming at obtaining female eggs. This process is usually completed in the reproductive center of the hospital. First, doctors will inject ovulation promoting drugs to women to promote the development of eggs. Then, the ultrasound guided needle was used to puncture the ovary and extract the eggs from the follicle. This process is usually given intravenous anesthesia to reduce pain and discomfort. After the eggs are taken, they will be sent to the laboratory for subsequent treatment.
In the laboratory, the eggs taken will be identified and evaluated. Only healthy and well developed eggs will continue to move on to the next step.
2. In vitro fertilization
In vitro fertilization is the combination of eggs and sperm to complete the fertilization process in the laboratory. After taking the eggs, the doctor will collect a sample of the man's semen. Then, the most active sperm will be selected from the semen samples. Then, the egg and sperm are put into the culture dish together to provide a suitable environment for fertilization. After a period of observation, the doctor will confirm whether the fertilization is successful.
After successful fertilization, the fertilized egg will continue to develop into an embryo.
3. Embryo transfer
Embryo transfer is to implant a well developed embryo into a woman's uterus so that it can continue to develop and become pregnant. Before embryo transfer, doctors will prepare the endometrium for women to provide a suitable receiving environment.
During the process of embryo transfer, the doctor will use a catheter to carefully implant the embryo into the uterus. This process is usually painless or only mild discomfort. After that, women need to rest to promote the implantation of embryos and continue to develop.
4. Pregnancy monitoring
Pregnancy monitoring is the last step in the IVF process to determine whether a pregnancy is successful. About one week to ten days later, women can conduct a serum pregnancy test to detect the presence of pregnancy hormone. If the result is positive, it means a successful pregnancy.
After that, the doctor will conduct further pregnancy monitoring, including detecting the level of pregnancy hormone and conducting ultrasonic examination to confirm the development of the embryo and the pregnancy in the uterus. After the pregnancy is confirmed, women need to carry out prenatal examination regularly to ensure the safety of mother and baby.
summary
IVF is a complex and sophisticated technology, involving multiple steps such as egg retrieval, in vitro fertilization, embryo transfer and pregnancy monitoring. These operations need to be carried out in the formal hospital reproductive center, and operated by professional doctors and teams. Through these steps, couples who cannot conceive naturally have the opportunity to realize their reproductive dreams.
