Evaluation of the success rate of IVF
IVF is a method of assisted pregnancy through in vitro fertilization technology, which has gradually become an option for infertile couples. However, the success rate of IVF is not 100%, and the specific results need to be judged after a certain period of time. The evaluation of IVF success rate will be elaborated from four aspects as follows.
1. Pregnancy rate
The pregnancy rate of IVF is one of the key indicators to evaluate its success rate. Generally, the hospital will make a preliminary judgment after the IVF cycle, and determine whether the pregnancy is successful by the results of the abdomen B ultrasound, progesterone, HCG and other blood tests of the pregnant woman. Generally speaking, the pregnancy rate of IVF is between 30% and 60%. The specific influencing factors include female age, reproductive system of both sides, embryo quality, etc. In addition, in the case of multiple cycles of trying to conceive, the pregnancy rate will be improved.
In addition, the pregnancy rate is also related to the number of embryos transferred. Multiple embryo transfer can improve the pregnancy rate, but it will also increase the risk of multiple births. Doctors will weigh it according to the specific situation.
2. Pregnancy rate
The pregnancy rate of IVF refers to the probability that the embryo will successfully conceive in the mother's body and continue to develop after successful pregnancy. Doctors usually assess whether pregnancy has successfully entered the pregnancy stage by carrying out progesterone, HCG and B-ultrasound examination. Pregnancy rate is affected by many factors, including embryo quality, endometrial condition, maternal age, etc. Generally, the pregnancy rate of IVF is between 20% and 40%.
It should be noted that pregnancy does not mean a successful delivery, and there will be a certain risk of miscarriage at the beginning of pregnancy. Therefore, in addition to the pregnancy rate, the quality and stability of embryonic development should also be considered.
3. Delivery rate
Delivery rate refers to the probability of successful delivery after IVF assisted reproductive technology pregnancy. The delivery rate is one of the important indicators to evaluate the success of IVF technology. According to relevant research data, the delivery rate of test tube babies is usually between 30% and 40%. However, this data is also affected by a series of factors, such as the age of pregnant women, basic health status, etc.
In order to improve the delivery rate, in addition to selecting high-quality embryos and suitable embryo transfer opportunities, the health management of pregnant women is also very important. The final delivery rate can be significantly improved by strengthening the health care during pregnancy and conducting timely prenatal examination and treatment.
4. Health status of pregnant women and newborns
The health status of pregnant women and newborns should also be considered when assessing the success rate of IVF. In the process of IVF, hormone therapy, ovarian stimulation surgery and other operations will be involved, which will have a certain impact on the body of pregnant women. After the success of IVF, we also need to pay attention to the birth weight and development of the newborn. The success rate of IVF can be more comprehensively evaluated by comprehensively considering the health status of pregnant women and newborns.
summary
To sum up, the success rate of IVF needs to be comprehensively evaluated from the pregnancy rate, pregnancy rate, delivery rate and the health status of pregnant women and newborns. These indicators are affected by many factors, including female age, embryo quality, individual physical condition, etc. The statistics and evaluation of these data by different hospitals may also be different. Nevertheless, IVF technology has achieved high success rates in many hospitals, and has brought fertility hope to infertile couples.
