Embryo transfer process of test tube baby
In vitro fertilization (IVF) baby is a reproductive technology that combines eggs and sperm in the laboratory, and then transfers the fertilized eggs into the female uterus to make them naturally develop into babies. Embryo transfer is one of the important steps in the IVF procedure. The following will elaborate on the selection of suitable embryos, embryo culture, the time of embryo transfer, and the method of embryo transfer.

Select suitable embryo
In the IVF procedure, appropriate embryos should be selected for transplantation to increase the success rate of pregnancy. Usually, during embryo culture, embryos will be observed in the laboratory to evaluate their quality. Generally, high-quality embryos have the following characteristics: active cell division, even embryonic cells, normal embryonic morphology, etc. By evaluating the morphology and development of the embryo, the doctor will select the best embryo for transplantation.
In addition, some women may have multiple embryos, and doctors need to decide the number of embryos to be transferred according to the patient's situation and the provisions of the medical ethics. Generally speaking, doctors will select suitable embryos for patients based on their age, health status, past medical history and other factors.
Embryo culture
After selecting the embryo, the embryo will be placed in a petri dish for further culture. Embryo culture refers to placing the fertilized egg in a culture dish containing suitable culture medium for its further development in the laboratory. Petri dishes will provide appropriate temperature, humidity, oxygen concentration and other environmental conditions to promote embryonic development.
Embryo culture usually lasts 3 to 5 days. During this period, doctors will regularly observe the morphology and development of embryos. Sometimes, doctors will conduct embryo monitoring to assess the quality and development ability of the embryo. Embryo monitoring technology, including real-time electronic progesterone monitoring and timing photography, can improve the accuracy of embryo selection to a certain extent.
Embryo transfer time
The time of embryo transfer is a very important link in the process of embryo culture. Generally speaking, embryos can be transferred after 3-5 days of culture. The choice of transfer time will be determined according to the embryonic development, the patient's physical condition and the doctor's suggestions.
In the process of using assisted reproductive technology, doctors sometimes reserve frozen embryos. Frozen embryos refer to storing the remaining high-quality embryos in liquid nitrogen through specific technology for future use. The advantage of frozen embryos is that they can be transferred at matching time in accordance with the physiological conditions of patients.
Methods of embryo transfer
Embryo transfer is usually carried out through painless procedures such as endometrial injection. During this process, the doctor will use a slender tube to slowly place the embryo in the endometrium. The whole procedure usually takes only a few minutes, and the patient will feel slight discomfort.
After embryo transfer, patients need to rest for a few hours. Generally, patients can perform normal activities, but they should avoid strenuous exercise and overwork.
After embryo transfer, patients also need to follow the doctor's advice and continue drug treatment to increase the success rate of pregnancy. In addition, the doctor will conduct regular inspection and pregnancy monitoring to ensure the patient's health and the smooth progress of pregnancy.
Summary
The process of IVF embryo transfer involves the selection of suitable embryos, embryo culture, the time of embryo transfer and the method of embryo transfer. The success rate of IVF pregnancy can be improved by selecting high-quality embryos, conducting appropriate embryo culture and precise embryo transfer. Embryo transfer is a key part of IVF technology. For those couples who want to have a successful pregnancy, embryo transfer is an important choice. However, considering that everyone's situation is different, it is recommended to consult a professional doctor for confirmation and decision-making according to individual conditions.
