What is the whole process of the second generation IVF?
The second generation of in vitro fertilization (IVF) refers to the technology that artificially combines sperm and egg to fertilize and develop embryos in vitro. This technology provides an opportunity for couples who cannot conceive naturally due to reproductive system problems. The whole process of the second generation IVF includes multiple stages, such as patient selection, in vitro fertilization, embryo culture and transplantation.
Patient preference
Before the second generation of IVF, the doctor will first conduct a detailed medical history and physical examination of the couple to determine whether they are suitable for this treatment. Generally, suitable patients include infertile couples, fallopian tube blockage, male sperm problems, etc. Then, patients need to undergo a series of physiological and biochemical tests, including ovulation function, endometrial status and hormone levels. These tests can help doctors determine the best treatment plan.
Next, the doctor will make a personalized treatment plan according to the patient's situation. According to women's ovarian function and ovulation, doctors will determine the best ovulation control program. For men, the quality and quantity of semen will affect the success rate of treatment, so doctors may recommend semen analysis. Finally, doctors will work out the most appropriate treatment plan based on all test results.
These initial steps are very important to ensure the success of the second generation of IVF. Through patient selection and comprehensive evaluation, the success rate can be improved to the greatest extent and unnecessary risks can be reduced.
In vitro fertilization
In vitro fertilization is one of the core steps in the second generation of IVF. It usually includes the following steps: ovarian stimulation, oocyte maturation, egg retrieval and sperm quality analysis.
Ovarian stimulation promotes ovarian development and ovulation by giving women drugs. This can increase the chance of success and reduce the number of times of egg retrieval. Later, doctors will use ultrasound technology to monitor the maturation of follicles. Once the follicle is mature, the doctor will use capillary puncture technology to remove the egg from the ovary.
At the same time, men need to provide fresh semen samples. The doctor will analyze the semen quality, including sperm quantity, vitality and morphology. If the semen quality is not ideal, doctors can recommend using semen treatment techniques to improve the chances of fertilization.
Once the eggs and sperm are ready, the doctor will place them in a petri dish. Create conditions similar to the internal environment in the laboratory to promote the fertilization of sperm and eggs. After fertilization, the doctor will observe the development of the embryo.
Embryo culture and transfer
In the second generation of IVF, embryo culture is a crucial step. After fertilization, the doctor places the embryo in a culture dish and provides it with appropriate nutrition and environmental conditions to promote its development. Doctors will regularly observe the development of embryos and evaluate their quality.
On the third or fifth day, doctors will choose the healthiest and best embryos for transplantation. This process is usually carried out through hysteroscopy, and the doctor will move the embryo into the uterus through the vagina. If the patient has more than one high-quality embryo, the doctor can choose to freeze it for future use.
Summary
Through the introduction of the whole process of the second generation of IVF, we can understand that patient selection, in vitro fertilization, embryo culture and transplantation are the key steps in this technology. Choosing suitable patients and developing personalized treatment plans are crucial to the successful implementation of IVF. In vitro fertilization and embryo culture require precise and meticulous operation and strict quality control. Through the application of these technologies, the second-generation IVF has become an effective way for many couples to realize their reproductive dreams.
