1、 Improve the success rate of IVF
IVF is a kind of assisted reproductive technology, which aims to help couples who have fertility problems realize their fertility dreams. The success rate of IVF is crucial for patients, and injection plays a key role in this process.
First, injection can adjust women's endocrine system and promote the development of follicles. By controlling the number and size of follicles through injection, doctors can better choose the best time to conceive. Secondly, injection can increase the probability of embryo implantation. Injecting progesterone and other drugs to women can maintain the thickness and stability of endometrium, provide a good growth environment for embryos, and thus improve the success rate of implantation. In addition, injection can also adjust women's immune system, reduce immune rejection, and improve the probability of embryo implantation.
In China, first-class hospitals such as Peking Union Medical College Hospital and Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine have all carried out IVF technology, using injection and other auxiliary means, successfully helping many couples usher in healthy babies.
2、 Promote the development and maturation of follicles
In the process of IVF, follicular development and maturation is a crucial step. The injection can adjust the hormone level to promote the growth and maturation of follicles by simulating the natural cycle of the human body.
Generally speaking, doctors will determine the appropriate number of follicles according to the individual conditions of patients after laboratory testing, and then inject ovulation promoting drugs to patients to stimulate follicular development. These ovulation promoting drugs, including human chorionic gonadotropin (hCG), can improve the development speed and number of follicles. When the follicle develops to the appropriate size, the doctor will arrange an egg collection operation to remove the eggs for subsequent in vitro fertilization and embryo transfer.
By injecting ovulation promoting drugs, the development and maturation of follicles in IVF can be better controlled and monitored, thus improving the success rate.
3、 Increase the quantity and quality of fertilized eggs
One of the key steps of IVF is in vitro fertilization, and injection can help increase the number and quality of fertilized eggs, thus increasing the success rate of IVF.
Before the injection, the doctor will determine the best fertilization method according to the laboratory test results. In general, doctors will recommend the use of in vitro fertilization (IVF) or single sperm microinjection (ICSI). By injecting specific ovulation promoting drugs, the ovary can develop more eggs and increase the number of fertilized eggs. At the same time, doctors will inject sperm into eggs before fertilization to improve the quality of fertilized eggs.
Through injection technology, the number and quality of fertilized eggs in IVF process have been improved, which helps to select high-quality embryos for transplantation, thus improving the success rate.
4、 Preventing complications and improving women's physical adaptability
In the process of IVF, women need to receive a series of injections aimed at preventing complications and improving physical adaptability.
In the early stage of IVF, doctors will inject women with anti infective drugs to prevent possible infection risks. In addition, for patients suffering from certain diseases or at risk of disease, doctors will also inject anticoagulants or drugs that inhibit the immune system according to the specific circumstances to reduce the adverse effects of diseases on the IVF process.
In addition, women's bodies need to recover and adapt after ovarian stimulation and egg retrieval. The doctor will give relevant injection drugs according to the patient's condition to promote the germination and recovery of the breast and prevent breast pain and distention.
Summary
In conclusion, IVF is injected to improve the success rate, promote the development and maturation of follicles, increase the quantity and quality of fertilized eggs, prevent complications and improve women's physical adaptability. Through injection and other auxiliary means, we can better control and adjust each key link in the process of IVF, so as to improve the success rate and realize couples' reproductive dreams.
