The process of IVF operation
IVF is a method of implanting the fertilized eggs into the mother's uterus through in vitro fertilization using artificial assisted reproduction technology to help couples who cannot conceive naturally achieve fertility. So, how does IVF operate? The following four aspects will be described in detail: egg taking, fertilization, embryo culture and transplantation.
Egg retrieval
The first step of IVF operation is to take eggs. In some regular hospitals, the egg retrieval process is generally carried out in the operating room, and patients receive general anesthesia. Doctors use ultrasound guided fine needles to puncture ovarian cysts or follicles to extract eggs. This process needs to be carried out under the careful operation of doctors to ensure the safety and success of the operation.
The removed eggs will be immediately sent to the laboratory for subsequent fertilization.
be fertilized
After taking eggs, the next step is fertilization. In the laboratory, the doctor places the eggs and partners or donated sperm in the culture dish, and sets appropriate environmental conditions, such as temperature, pH, etc. After a period of time, the egg and sperm will fertilize themselves.
In some cases, if the egg and sperm cannot be successfully fertilized themselves, doctors can also choose assisted fertilization technology, such as in vitro sperm injection (ICSI), which injects a single sperm into the egg to increase the success rate of fertilization.
After successful fertilization, the embryo will continue to be cultured.
Embryo culture
In the laboratory, embryos will be placed in a specific medium and cultured under certain environmental conditions. In order to improve the development and survival rate of embryos, students will adjust the composition of the culture medium during the culture process to meet the needs of embryonic development.
Generally, the cultivation process will last for 3 to 5 days. Doctors will regularly observe the development of embryos to assess their quality and survival rate. The end point of embryo culture is usually to reach the division stage of 5 to 6 cells, or to reach the blastocyst stage.
embryo transfer
After the completion of embryo culture, the last stage is embryo transfer. Doctors will select the best growing and quality embryos from the culture dish, and then use a thin tube to insert them into the mother's uterus and implant the embryos into the endometrium.
Embryo transfer is a minimally invasive surgical procedure, which generally does not require general anesthesia. Doctors use ultrasound guidance to ensure that the embryo is properly placed in the uterus. After the operation, the patient needs to rest for a period of time and take some medicine to help the implantation and stabilization of endometrium.
To sum up, the operation process of IVF includes egg retrieval, fertilization, embryo culture and embryo transfer. Each step requires careful operation and accurate technology to increase the success rate of IVF. Through these steps, couples who are unable to conceive naturally have the opportunity to realize their fertility aspirations.
