Flow chart of IVF: How to implement IVF technology? 1. Preparation for IVF
The implementation of IVF technology requires a series of preparations. First of all, both husband and wife need to have a comprehensive physical examination, including blood examination, ultrasonic examination, etc., to understand their fertility. Then, the doctor will make a treatment plan based on the examination results. Next, the woman needs to receive ovulation induction treatment and use drugs to regulate ovulation to increase the chance of pregnancy.
After ensuring that the ovulation of the woman is normal, the next step is to take the eggs. This process is usually carried out in the operating room, and the doctor will use ultrasonic guidance to remove the eggs through needle puncture. At the same time, the man needs to provide sperm samples for subsequent in vitro fertilization.
After taking the eggs, the eggs and sperm will be fertilized in vitro in the culture dish. The culture and development of fertilized eggs usually take 3-5 days. The doctor will monitor the development of the fertilized egg and select the best fertilized egg for transplantation.
2. IVF embryo transfer
Embryo transfer is a key step in IVF technology. The doctor will put the fertilized egg into the uterus through a catheter at an appropriate time. This process generally requires no anesthesia and will not cause severe pain.
After embryo transfer, the woman needs a fixed time of rest, and the doctor will give hormone drug support according to the specific situation. About two weeks later, a blood pregnancy test was performed to determine whether the pregnancy was successful.
3. Follow up treatment of IVF
If the pregnancy result is positive, that is, the pregnancy is successful, and further pregnancy security measures need to be taken. Doctors will provide drug support for pregnancy maintenance, and conduct regular pregnancy monitoring to ensure the safe development of embryos. At the same time, both husband and wife need to pay attention to the adjustment of diet, work and rest, and maintain good living habits.
If the pregnancy result is negative, that is, the pregnancy fails, the doctor will analyze according to the specific situation and formulate the next treatment plan. Sometimes, the second or third attempt of IVF may be necessary to increase the chance of successful pregnancy.
4. Risks and precautions of IVF
Although IVF technology has made great progress, there are still some risks and precautions. First, ovulation promoting drugs may cause multiple egg development, increasing the risk of multiple pregnancies. Secondly, IVF technology is not applicable to all infertile patients, and doctors will evaluate and make decisions according to the specific situation.
In addition, although IVF technology can increase the chance of pregnancy success, it cannot guarantee 100% success rate. In other words, even after many attempts, pregnancy may not be achieved. Therefore, before deciding to carry out IVF technology, both husband and wife need to fully understand the risks and possible results, and be prepared psychologically.
In general, IVF technology is a complex and sophisticated medical technology, including preliminary preparation, egg retrieval and in vitro fertilization, embryo transfer, pregnancy security and other steps. Although not every attempt will succeed, for couples with fertility difficulties, IVF technology is an important choice, which can help them achieve their reproductive aspirations.
Conclusion: Through the introduction of this article, we understand the specific process and precautions of IVF technology. Although this technology has certain risks, under the guidance of doctors, it can help those couples who have difficulties in childbearing realize their dreams. We hope that through continuous scientific research and technological innovation, we can further improve the success rate of IVF technology and help more couples to build happy families.
