IVF Egg Culture Process
IVF is a kind of assisted reproduction technology, which is used to fertilize eggs and sperm in vitro, and then transfer the fertilized eggs to the mother's uterus for pregnancy. The IVF egg cultivation process involves multiple steps, including ovarian stimulation, egg collection, in vitro fertilization and embryo transfer. The following will introduce the IVF egg cultivation process in detail from these four aspects.
1. Ovarian stimulation
Ovarian stimulation is the first step in the IVF egg culture process. From the first 2-3 days of the normal menstrual cycle, the patient receives gonadal hormone injection to promote the ovary to produce more eggs. Doctors will develop personalized drug programs according to the patient's condition and constitution, and often conduct ultrasound and blood tests to monitor ovarian response.
Generally, stimulation lasts for 8-14 days. Once the follicle has grown to the proper size and the egg cell has reached maturity, the doctor will use the drug to terminate the maturation of the follicle to prepare the egg cell for collection as scheduled.
2. Egg collection
Egg collection is a key step in the IVF egg cultivation process. This operation is usually performed in the operating room, and the patient receives local anesthesia or general anesthesia. Doctors will use ultrasound guided fine needles to puncture the fallopian tube and extract eggs from the ovary. The acquisition process usually lasts from 30 minutes to 1 hour.
After collection, the eggs will be immediately sent to the laboratory for in vitro culture and fertilization. At the same time, patients will also receive some adjuvant treatment, such as antibiotics to prevent infection.
3. In vitro fertilization
In vitro fertilization (IVF) is the core step of IVF egg cultivation process. After the eggs are collected, laboratory technicians will place multiple sperm and eggs together in the culture dish. Such tissue culture conditions can simulate the internal environment of women and provide the best conditions for fertilization.
After fertilization, the eggs will be kept in the culture dish to form the blastocyst stage. Generally, the first cell division occurs 24 hours after fertilization, and more cells will be formed 72 hours after fertilization. Doctors will select an appropriate time point for embryo transfer according to the development of embryos.
4. Embryo transfer
Embryo transfer is the last step in the IVF egg cultivation process. Embryo transfer is usually carried out 3-5 days after fertilization. This process is similar to hysteroscopy, in which embryos are placed in the uterus. Anesthesia is not required for transplantation, but sedatives can be provided to patients to reduce discomfort.
After successful embryo transfer, the patient will receive rest and monitoring to ensure that the embryo can grow and develop well. If the embryo is successfully implanted, that is, pregnancy occurs, and the patient will continue to receive follow-up maternal care.
summary
IVF egg cultivation process includes ovarian stimulation, egg collection, in vitro fertilization and embryo transfer. This process relies on the professional operation and monitoring of doctors and technicians, which is a complex and sophisticated technology. Through the above steps, the success rate of IVF has been improved, providing a hope for couples who cannot conceive naturally. Before IVF egg cultivation, patients should fully understand the whole process and select qualified doctors for guidance and treatment in professional hospitals.
