How many attempts does IVF need to make to succeed?
Test tube baby is an assisted reproductive technology. It develops in vitro by combining sperm and egg in the laboratory, and then implants the embryo into the mother's uterus for pregnancy. However, not every attempt can succeed, so how many attempts does IVF need to go through to succeed? The following will be detailed from four aspects: pregnancy rate, embryo quality, individual differences and medical conditions.
Pregnancy rate
The pregnancy rate of IVF is an important factor affecting the success rate. The pregnancy rate is affected by many factors, including women's age, the quality of eggs and sperm, and the technical level of in vitro fertilization.
First of all, women's age is one of the important factors affecting the pregnancy rate. Generally speaking, the ability of women to conceive decreases with the increase of age, especially for women over 35 years old, the pregnancy rate will be significantly reduced. Therefore, for older women, it may take several attempts to succeed.
Secondly, the quality of eggs and sperm will also affect the pregnancy rate. The quality of eggs and sperm is related to individual gene quality, and gene quality is affected by many factors, including genetic factors and environmental factors. If the quality of eggs and sperm is poor, the probability of pregnancy will be relatively low, and it may take several attempts to succeed.
Finally, the level of IVF technology will also affect the pregnancy rate. With the progress of science and technology, in vitro fertilization technology has been constantly improved and perfected, and the pregnancy rate is also constantly improving. If the selected hospital has a high level of technology, then the probability of pregnancy will be relatively high.
Embryo quality
Embryo quality refers to the quality of embryos developed after in vitro fertilization. Good embryo quality means higher implantation rate and pregnancy rate.
During in vitro fertilization, doctors will select the best embryo for implantation according to the development and quality of the embryo. If the embryo quality is poor, the probability of success will be relatively low. Therefore, if high-quality embryos cannot be obtained after several consecutive attempts, more attempts may be needed to succeed.
In addition, hospital embryo culture technology will also have an impact on embryo quality. Good embryo culture technology can provide a better growth environment, which is conducive to the healthy development of embryos, thus improving the probability of success.
individual difference
The success rate of IVF is also related to individual differences. Everyone's physical condition and physiological function are different, and different individuals may have different reactions to the same operation and treatment.
Some individuals may be more sensitive to treatment and easy to succeed, while others may need more attempts to succeed. This is related to the individual's physical condition, health status, living habits, etc. Therefore, it is necessary to carry out individualized treatment plans according to the actual situation of individuals in order to improve the probability of success.
Medical conditions
Medical conditions are also one of the important factors affecting the success of IVF.
First of all, choosing a formal and reputable hospital is crucial to the success rate. Regular hospitals have professional doctor teams and advanced equipment, which can provide better technical support and medical services, thus improving the probability of success.
Secondly, the comprehensive strength of the hospital will also affect the probability of success. The stronger the comprehensive strength of the hospital in facilities, services, teams, etc., the better the IVF service provided, and the higher the probability of success.
Finally, in the case of relatively good medical conditions, it may only take a few attempts to succeed. However, if the conditions are relatively poor, more attempts may be required to achieve success.
Summary
The success of IVF depends on several factors. Pregnancy rate, embryo quality, individual differences and medical conditions all affect the probability of success. The age of women, the quality of eggs and sperm, and the technical level of hospitals are important factors affecting the pregnancy rate, while the quality of embryos and the embryo culture technology of hospitals affect the quality of embryos. Individual differences will also lead to different individual responses to IVF. In addition, choosing a regular hospital and good medical conditions will also increase the probability of success. To sum up, it is a complex problem how many attempts test tube babies need to go through before they can succeed. It is necessary to consider multiple factors comprehensively and develop individualized treatment plans for each couple to improve the probability of success.
