Embryo transfer process of test tube baby
With the development of IVF technology, many infertile couples have realized their dream of procreation. Embryo transfer is a crucial step in this process. This article will elaborate on the process of IVF embryo transfer from four aspects of embryo culture, selection, transfer and follow-up observation.
Embryo culture
Embryo culture is the first step in IVF embryo transfer. Generally, hospitals that conduct IVF operations in assisted reproductive medicine clinics will be equipped with advanced embryo culture rooms. In the embryo culture room, the embryo will be placed in a certain temperature, humidity and oxygen concentration environment to provide the most suitable growth conditions. During the process of embryo culture, doctors will conduct regular observation and evaluation to ensure that the embryo has a good development condition.
The embryo culture medium in the culture room will provide the nutrients needed by the embryo to ensure the normal development of the embryo. In the process of embryo culture, doctors may use pregnancy aid drugs to increase the success rate of embryo implantation. The time for embryo culture is generally 3-5 days. According to the quality and development of the embryo, the doctor will determine the best transfer time.
Embryo selection
The success of IVF is closely related to the quality of embryos, so the selection of embryos is very important. In the process of embryo culture, doctors will evaluate the embryos and screen the most likely successful embryos according to certain criteria. The main evaluation indicators included the number of cells in the embryo, cell morphology, cell division, etc.
Generally, high-quality embryos have more cells and regular cell morphology, and cell division is normal. According to these indicators, doctors will select the best embryos for transplantation to improve the possibility of IVF success. At the same time, auxiliary technologies such as gene screening can also help to select more suitable embryos to a certain extent.
Embryo transfer
After the completion of embryo culture, transfer is a key step in the process of IVF. Transplantation is generally carried out in the operating room, and the whole process requires no anesthesia, only local anesthesia. The doctor will use a slender catheter to carefully place the embryo in the endometrium to ensure its smooth implantation.
Embryo transfer is usually carried out in the best state of endometrium, which is closely related to the time of embryo culture. The doctor will select the most appropriate transfer time according to the endometrial status and the development of the embryo. The whole transplantation process usually takes only a few minutes. After surgery, patients need to pay attention to rest and avoid tension and strenuous exercise.
Observation after embryo transfer
After embryo transfer, patients need to be observed under the guidance and monitoring of doctors. The doctor will arrange an appropriate time for embryo implantation inspection to determine whether the transfer is successful. After embryo implantation, the secretion of pregnancy hormone will gradually increase, thus confirming pregnancy.
After embryo transfer, patients may have some reactions after embryo transfer, such as breast pain, abdominal distension, slight abdominal pain, etc. This is a normal phenomenon, and patients need not worry too much. However, if the patient has obvious abdominal pain, continuous bleeding, high fever and other abnormalities, it should be reported to the doctor in time.
summary
IVF embryo transfer is a complex and delicate process, including embryo culture, selection, transfer and follow-up observation. The success rate of IVF can be improved by precise operation, reasonable selection of embryos and transplantation. It should be noted that each woman's physical condition and individual differences are different, so before accepting IVF operation, comprehensive consultation and inspection must be carried out in a regular hospital to ensure the safety and effectiveness of the operation.
