1. Definition and process of IVF
IVF, also known as assisted reproductive technology (ART) or in vitro fertilization (IVF), is a technology that helps couples who cannot conceive naturally to achieve their reproductive goals. At present, Hebei Second Hospital is one of the first hospitals in Hebei Province to set up a test tube baby center.
The process of IVF includes four main steps: ovulation, pregnancy, in vitro fertilization and embryo transfer. First, doctors will stimulate ovarian ovulation by injecting women with hormones. Then, when a woman's ovary ovulates, the doctor will use a slender needle to extract mature eggs from the ovary. Next, in the laboratory, doctors will take out the eggs and male sperm for in vitro fertilization. Finally, after cultivation, doctors will choose the healthiest embryo to transplant back to the mother.
2. Two main methods of IVF
There are two main methods adopted by the IVF Center of Hebei Second Hospital: the natural combination of eggs and sperm and the assistance of micromanipulation.
The natural combination of egg and sperm refers to the natural combination of the extracted egg and male sperm by placing them directly in the culture dish. The advantages of this method are simple operation and high success rate. However, for couples with certain gamete quality problems, the natural combination of eggs and sperm may reduce the success rate.
Micromanipulation assistance refers to the use of microscopes and precision tools to assist the combination of eggs and sperm. This method can accurately select the healthiest embryo and improve the success rate before the final embryo transfer. However, micromanipulation has high technical requirements and increases the risk of surgery.
3. Therapeutic indications and non indications of IVF
The indications that can be treated by the IVF Center of Hebei Second Hospital include infertility caused by fallopian tube factors, azoospermia, ovulation disorder and some more complex infertility. For couples with these causes that cannot be treated by other methods, IVF is a better choice.
However, due to individual differences and technical constraints, IVF is not applicable to all infertile couples. Some infertile people with definite causes may need other treatments.
4. Combined with the above analysis, which method is better?
From the above analysis, it can be seen that the natural combination method of egg and sperm is relatively simple, with a wide range of applications and a high success rate. However, for couples with certain problems in the quality of eggs and sperm, the success rate may be reduced.
In contrast, micromanipulation assisted method can select the healthiest embryo before the final embryo transfer to improve the success rate. However, this method has higher technical requirements and higher surgical risks.
Therefore, decide which method is better according to the individual situation. For most cases, the natural combination of egg and sperm adopted by the IVF Center of Hebei Second Hospital is a better choice. Only in special cases, such as when there are obvious problems with the quality of eggs and sperm, the use of micromanipulation assisted methods should be considered.
summary
To sum up, the IVF Center of Hebei Second Hospital provides different treatment methods, including natural combination of egg and sperm and micro manipulation assistance. These two methods have their own advantages and disadvantages, and adapt to different individual situations. Through the analysis of indications, operation process and success rate, couples can choose appropriate methods. For most couples, the natural combination of eggs and sperm is a better choice.
