Abortion rate of IVF
Test tube baby is a kind of assisted reproductive technology, which helps many couples who cannot conceive naturally realize their desire to have children. However, the abortion rate of IVF has always been a concern. However, we cannot say that the IVF abortion rate is high, because the abortion rate is affected by many factors. The following details the actual situation of IVF abortion rate from various aspects.
Couples with basic diseases
Some couples who want to give birth through IVF may suffer from some basic diseases, such as abnormal uterus, hormone imbalance, etc. These diseases will increase the risk of IVF abortion. For example, women with endometriosis may be affected by endometriosis after IVF embryo transfer, resulting in abortion. Some women with hormone imbalance are also prone to difficulties in embryo implantation, increasing the risk of miscarriage.
In addition, when men suffer from chromosome defects or poor sperm quality, the sperm they provide to the embryo may also have problems, which may lead to increased risk of embryo abnormalities and miscarriage. Therefore, if one of the couples has basic diseases, it is recommended to strengthen detection and treatment in the process of IVF to reduce the abortion rate.
Age factor
Female age is one of the important factors affecting the rate of IVF abortion. When a woman is over 35 years old, her fertility begins to decline. With the increase of age, the quality of female eggs decreases and the risk of chromosomal abnormalities increases, leading to difficulties in embryo implantation and an increase in the probability of miscarriage. According to the actual statistics, the abortion rate of IVF for women over 35 years old may be as high as 30%, much higher than that of younger women.
However, this does not mean that all older women will miscarry. IVF technology and medical progress can also improve the prediction accuracy of abortion rate and reduce the risk of abortion. Doctors can conduct a comprehensive physical examination and assessment of women to further reduce the risk of miscarriage.
Embryo quality
IVF obtains embryos through artificial fertilization or in vitro fertilization, and then transfers healthy embryos to the mother's uterus for development. The quality of embryos has a direct impact on the success rate and abortion rate of IVF. If the embryo itself has chromosome abnormalities, gene defects or embryo development problems, the possibility of successful implantation and development will be reduced, and the risk of abortion is relatively high.
In some cases, scientists and doctors can conduct genetic and genetic tests on embryos to screen the healthiest embryos for transplantation, so as to improve the success rate of IVF and reduce the abortion rate.
Other factors
In addition to the above factors, there are many other factors that may affect the IVF abortion rate. For example, the mother's lifestyle, eating habits and environmental factors may have a certain impact on the abortion rate. Exposure to radiation, chemicals and harmful environments should be avoided as far as possible, and good living habits should be maintained to increase the success rate of IVF.
In general, the abortion rate of IVF is affected by many factors, which cannot be generalized. Through professional medical team and proper medical management, the abortion rate can be effectively controlled. Couples should fully understand their own situation before choosing IVF technology, and assess the abortion risk according to the actual situation to make better decisions.
