IVF survival rate and in vitro fertilization
Test tube baby refers to the baby developed by implanting the pregnant egg into the mother's uterus after it is cultivated to a certain stage through in vitro fertilization technology. With the continuous development of science and technology and the progress of medical technology, IVF has become the choice of many infertile couples to achieve their reproductive aspirations. However, the survival rate of IVF is closely related to IVF technology.
In vitro fertilization process and advantages
In vitro fertilization (IVF) refers to the artificial combination of eggs and sperm in vitro and the implantation of embryos into the mother's uterus after multiple cell stages. First, doctors will collect female eggs and male sperm, and combine the two in the laboratory. The successfully fertilized embryos are then cultured for several days to ensure that they develop to the appropriate stage. Finally, doctors transfer the embryo into the mother's uterus, hoping that it can be successfully implanted and developed.
Compared with other assisted reproductive technologies, such as IVF, IVF has multiple advantages. First of all, in vitro fertilization provides fertility opportunities for couples who are unable to conceive naturally due to problems such as uterine malformation and tubal obstruction. Secondly, IVF has high precision and success rate, which can avoid those genetic factors that may lead to fetal abnormalities. In addition, in vitro fertilization also provides the possibility of genetic screening and sex selection of embryos.
Influencing factors of IVF survival rate
The survival rate of IVF is affected by many factors, including age, basic health conditions, the quality of eggs and sperm, and the timing of embryo implantation. Age is one of the most important factors. The older a woman is, the lower the success rate will be. Other health factors, such as weight, diet, smoking and alcohol abuse, also have some influence on the survival rate of IVF.
In addition, the quality of eggs and sperm is also an important factor affecting the survival rate of IVF. The decline of egg quality may lead to difficulty in fertilization or abnormal embryonic development, which may reduce the implantation and survival rate. The decrease of sperm quality may lead to the decrease of fertilization rate. Therefore, it is very important to comprehensively evaluate and screen eggs and sperm before in vitro fertilization.
In addition, the timing of embryo implantation also affects the survival rate of IVF. Endometrial status and quality of implanted embryos at the time of implantation will affect implantation and survival rate. Doctors usually choose the appropriate implantation time according to the good condition of endometrium and the development of embryo to improve the survival rate.
summary
The survival rate of IVF is closely related to IVF technology. As an assisted reproductive technology, in vitro fertilization (IVF) has the advantages of high precision and success rate, which provides an opportunity for infertile couples to achieve their reproductive aspirations. However, the survival rate of IVF is affected by many factors, including age, basic health conditions, the quality of eggs and sperm, and the timing of embryo implantation. Therefore, before IVF, eggs and sperm should be comprehensively examined and screened, and attention should be paid to adjusting personal lifestyle and health. By comprehensively considering the above factors, the survival rate of IVF can be improved, so as to better realize the fertility aspirations of infertile couples.
