How long will IVF succeed?
IVF refers to the process of pregnancy and delivery by culturing the fertilized eggs in vitro through assisted reproductive technology and then transferring the cultured embryos to the mother. Among couples who choose IVF, one of the most concerned issues is the success rate and time required for IVF. The following will elaborate on the success time and influencing factors of IVF from four aspects.
1. In vitro fertilization success rate
IVF is the first step of IVF, and its success rate directly affects the overall success rate of IVF. There are many key factors for successful IVF, including women's age, quality of eggs and sperm, control and quality of ovulation induction process, conditions for embryo culture, etc. Generally speaking, young women, couples with good ovarian function and good egg and sperm quality have a higher success rate of IVF. At the same time, the technical level and equipment conditions of the hospital will also affect the success rate of IVF.
However, even if all conditions are met, IVF cannot guarantee the success of every cycle. According to statistical data, the success rate of IVF is 40% - 50% for women under 30 years old, 30% - 40% for women 30-35 years old, and 20% - 30% for women over 35 years old. Therefore, the success of IVF requires patient patience and persistence, and it usually requires multiple cycles to achieve success.
2. Implantation rate after embryo transfer
IVF embryo transfer is the next step after successful IVF. In the process of transplantation, many factors will affect the implantation rate of embryos, such as the quality of embryos, the quality and status of endometrium, the rest and diet before and after transplantation. Generally speaking, the better the embryo quality, the higher the implantation rate.
After embryo transfer, it needs to wait for a period of time before pregnant women can be tested to confirm whether pregnancy is successful. Generally speaking, the implantation rate of IVF embryo transfer is about 30% - 40%. If a migration fails, you can try multiple migrations to improve the success rate.
3. Maternal health and perinatal management
After the success of IVF, the health status of pregnant women and perinatal management also play an important role in continuous pregnancy and successful delivery. Pregnant women should follow the doctor's advice, carry out prenatal examination, reasonable diet, moderate exercise, and avoid fatigue and excessive stress. At the same time, the perinatal management of the hospital also plays a key role, including monitoring from the injection of ovulation promoting drugs, regular prenatal examination, reasonable nutrition guidance, etc.
4. Technical level and conditions of the hospital
The technical level and conditions of hospitals have a direct impact on the success rate of IVF. Advanced technical equipment and professional medical team can improve the success rate of IVF. In China, some well-known hospitals such as Peking Union Medical College Hospital and Shanghai Renji Hospital have high reputation in the field of IVF.
Summary
The success time of IVF depends on many factors, including the success rate of IVF, the implantation rate after embryo transfer, maternal health and perinatal management, and the technical level and conditions of hospitals. In general, the success of IVF requires multiple cycles of attempts, and medical data show that the success rate varies among women of different ages. Therefore, couples should be patient and persistent, reasonably choose hospitals, and follow the doctor's advice in order to improve the success rate of IVF.
