What is IVF?
In Vitro Fertilization (IVF) is a kind of assisted reproductive technology, which is used to help couples who cannot conceive naturally realize their fertility aspirations. This technology combines the female egg with the male sperm in an in vitro culture dish, develops into a fertilized egg, and then implants it into the female uterus, so as to achieve the purpose of pregnancy and fertility.
Relevant setting operations of IVF
1. Ovulation induction therapy:
The first step in setting up IVF is ovulation induction therapy, which helps women produce and collect enough mature eggs. This process is usually achieved by receiving an injection of ovulation promoting drugs to increase the number of eggs. The doctor will determine the appropriate ovulation promotion program according to women's age, ovarian function, ovulation rule and other factors.
2. Egg retrieval:
During ovulation induction treatment, doctors will use ultrasound guided needle aspiration technology to remove mature eggs from the ovary. This process is usually carried out in the operating room, using local anesthesia or general anesthesia. During the process of egg retrieval, doctors will use ultrasonic instruments to guide the needle into the ovary and suck out the eggs. The eggs will be immediately sent to the laboratory for further treatment.
3. Extract:
At the same time, doctors need to extract sperm from men's semen, which can be done through natural ejaculation or direct sperm extraction. If the quality of semen sample is low or the male suffers from semen problems, semen can also be pretreated through semen freezing and thawing technology to improve fertilization ability.
4. Fertilization and embryo culture:
In the laboratory, the doctor combines the eggs taken out with the sperm obtained to achieve fertilization. This can be done by adding sperm directly around the egg in the culture dish, or by injecting a single sperm into the egg using the single sperm injection technique.
After fertilization, the fertilized egg will be transferred to the culture dish for further development. The doctor will decide the best embryo transfer time according to the number and quality of fertilized eggs, the patient's age, medical history and other factors, usually within 2 to 6 days after fertilization.
Relevant setting operations of IVF
1. Embryo selection:
In the process of embryo development, doctors will evaluate different embryos to select the best embryo for implantation. The evaluation criteria include the number, internal quality, cell division rate and morphological structure of embryos. High quality embryos are more likely to successfully implant and develop into healthy fetuses.
2. Embryo implantation:
Embryo implantation is the last step of IVF treatment. The doctor inserts the selected embryo into the female uterine cavity through a catheter and helps her to implant on the uterine wall. This process is usually carried out in the doctor's office or operating room without anesthesia.
3. Pregnancy test:
About two weeks later, the doctor will conduct a blood pregnancy test to determine whether the pregnancy was successful. If the result is positive, then the woman is likely to be pregnant with a test tube baby.
Summary
IVF is an assisted reproductive technology that can solve the problem of natural pregnancy through in vitro fertilization and embryo implantation. The process includes ovulation induction therapy, egg retrieval, sperm retrieval, fertilization and embryo culture. At the same time, embryo selection and implantation as well as pregnancy detection are also important links in this process. Through these settings and operations, IVF provides an effective way for couples who cannot conceive naturally.
