Operation process of domestic IVF
IVF is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally due to physiological or other reasons to realize their reproductive dreams. In China, all major hospitals provide IVF services. The following details the operation process of IVF in China.
1. Inspection and evaluation
First, both husband and wife need to go to a professional reproductive medical center for examination and evaluation. These examinations include male semen analysis, female ovarian function examination and tubal patency examination. The doctor will evaluate the fertility potential of both the husband and wife according to the examination results to determine whether it is suitable for IVF.
Next, the doctor will develop a personalized treatment plan. The program includes the use of ovulation promoting drugs to stimulate female ovulation, and regular monitoring of follicular development to determine the best time for pregnancy. For women who cannot ovulate, artificial insemination or oocyte extraction can be used for in vitro fertilization.
During the development of the treatment plan, the doctor will explain the operation process and possible risks to both the husband and wife in detail and obtain their consent.
2. Ovarian stimulation and egg collection
According to the treatment plan, women will experience ovarian stimulation for a period of time. The doctor will prescribe the dosage and use time of ovulation promoting drugs according to the specific situation. Ovulation promoting drugs can stimulate ovarian development and increase the number of ovulatory follicles.
When the follicle develops to the appropriate size, the doctor will arrange an egg collection operation. The operation is usually performed before and after ovulation of women with unobstructed fallopian tubes, and vaginal puncture is adopted. During the operation, doctors will use ultrasound guidance to collect mature eggs in the ovary through puncture.
Egg collection is a minimally invasive operation, which generally requires general anesthesia. After the operation, the eggs collected will be immediately transferred to the laboratory for in vitro fertilization.
3. In vitro fertilization and embryo culture
In the laboratory, the doctor will put the sperm and egg together in the culture dish according to the in vitro fertilization technology, and let them conduct fertilization and embryonic development under the appropriate temperature and nutrition conditions. Generally, the incubation process lasts for 3-5 days.
In the process of embryo culture, doctors will evaluate the development of embryos according to the quality of embryos. Usually, one or several high-quality embryos are selected for transplantation or cryopreservation. The doctor will discuss with the couple and determine the number of embryo transfers according to their wishes, age and other factors.
4. Embryo transfer and pregnancy observation
Embryo transfer is the last step of IVF. The doctor will put the embryo into the female uterine cavity through a vaginal catheter. The transplantation process is similar to cervical dilatation surgery or endometrial biopsy, and generally does not require general anesthesia.
After transplantation, women should pay attention to rest and avoid strenuous exercise and overwork. About two weeks later, the doctor will conduct a blood pregnancy test to check whether the pregnancy is successful.
In conclusion, the domestic IVF procedures mainly include inspection and evaluation, ovarian stimulation and egg collection, IVF and embryo culture, embryo transfer and pregnancy observation. This process requires the active cooperation of both husband and wife and the careful operation of doctors. The continuous progress of IVF technology and the development of reproductive medicine have brought new hope to those couples who are eager to have children.
