What is the process of IVF?
In Vitro Fertilization (IVF) is an assisted reproductive technology to help infants conceive, which is usually used for couples who have difficulty in natural pregnancy. The process of IVF includes many steps, from preparation to embryo transfer, which has made important contributions to the realization of couples' dreams.
1. Preparation before birth
Before IVF treatment, the doctor will conduct a detailed physical examination of the couple to understand their medical history and birth history. These tests will help doctors determine appropriate treatment options and eliminate any potential risks that are not suitable for IVF treatment. In addition, women also need female endocrine examination to ensure that their ovaries can ovulate normally.
Once the doctor has determined that IVF treatment is the right choice for couples, the next step is to inject ovulation promoting drugs to women to increase their number of eggs. This can improve the chance of pregnancy and obtain more high-quality eggs.
In addition, the man also needs to provide semen samples for sperm quality inspection, and take corresponding measures to improve sperm quality as needed. If the quality of men's sperm is poor, doctors may recommend using sperm donation to improve the chance of pregnancy.
2. Egg collection and sperm collection
Egg collection and sperm collection are usually carried out simultaneously. Within 36 hours after ovarian ovulation is triggered, doctors will use ultrasound guided fine needles to remove the eggs. This process is usually completed in the operating room. At the same time, the man provides semen samples for the subsequent fertilization process.
3. Fertilization process and embryo culture
After the eggs and sperm are placed in a culture dish for natural fertilization, the doctor will observe whether the fertilization is successful. If fertilization is successful, a fertilized egg will be formed and further divided into embryos. These embryos will be cultured in the laboratory, which usually takes 3 to 5 days.
In the process of embryo culture, doctors will regularly check the embryo to assess its quality and development. This will help doctors decide to select the best embryo for subsequent transplantation.
4. Embryo transfer and pregnancy testing
Once the embryo culture reaches the ideal state, the doctor will select the best embryo for transplantation. This process is simple and less painful, and is usually carried out in the operating room. Doctors will use a thin tube to transfer the embryo into a woman's uterus in the hope of a successful pregnancy.
About two weeks later, a pregnancy test will be conducted to confirm whether the pregnancy is successful. If the result is positive, then the woman is likely to be pregnant. Next, she will conduct a routine prenatal examination to observe the development of the embryo, and make an appointment with an obstetrician in advance to ensure the safety of the mother and baby.
In summary, the process of IVF starts with preparations, including examination and physical examination, followed by egg collection and sperm collection, followed by fertilization and embryo culture, and finally embryo transfer and pregnancy testing. Each step is carefully planned and operated to ensure the best results. IVF technology provides a light of hope for couples who are eager to have children but have difficulty in natural pregnancy.
