Causes of IVF abortion
IVF abortion refers to the situation that embryos cannot continue to develop in the uterus and eventually lose in the process of assisted reproductive technology (ART). The causes of IVF abortion can be analyzed from many aspects.
Genetic factor
Some causes of IVF abortion are related to genetic factors. First of all, in the process of natural selection of embryos, if chromosomal abnormalities or gene mutations occur, it may lead to abortion. Secondly, if a family has a history of genetic disease or abortion, the genetic risk of IVF will increase. In addition, age is also an important factor affecting the genetic quality of embryos. The increasing age of women will increase the risk of chromosomal abnormalities, which will lead to an increased probability of miscarriage.
To prevent IVF abortion caused by genetic factors, we can conduct gene screening in the process of assisted reproductive technology, exclude embryos carrying abnormal genes, and select healthy embryos for transplantation.
Uterine factor
Uterine factors such as uterine malformations and endometrial abnormalities are also one of the reasons for IVF abortion. Uterine malformations include uterine septum, adenomyosis, etc. These conditions can lead to difficulties in embryo implantation or abnormal placental development, leading to abortion.
To prevent IVF abortion caused by uterine factors, uterine examination can be carried out before IVF, and surgical correction can be carried out in time if abnormal conditions are found. At the same time, the endometrium is evaluated before the test tube baby to ensure the health of the endometrium.
Immune factor
Immune factors are also a major reason for IVF abortion. Immune factors include anti embryonic antibody, anti sperm antibody, etc. Antiembryonic antibodies can cause the maternal immune system to attack the embryo, while antisperm antibodies can cause sperm to be attacked by the immune system, thus affecting the development of the embryo.
To prevent IVF abortion caused by immune factors, immunotherapy or immunosuppressive drugs can be used to regulate the maternal immune system and reduce the attack of the immune system on the embryo.
Lifestyle factors
Lifestyle factors also affect the risk of IVF abortion. Bad habits such as smoking, drinking and drug abuse will increase the probability of miscarriage. In addition, excessive physical activity and pressure will also adversely affect the development of embryos.
Preventing IVF abortion caused by lifestyle factors can reduce the risk of abortion by improving living habits. Quit smoking and drinking, avoid excessive physical activity and pressure, and maintain a reasonable schedule.
How to avoid IVF abortion
In order to reduce the risk of IVF abortion, we can prevent it from the following aspects:
Comprehensive health examination
It is very important to have a comprehensive health examination before IVF. It includes the examination of uterus shape, endometrium, hormone level, etc. for women, and the examination of sperm quality, sperm antibody, etc. for men. Through these inspections, existing problems can be found in time and treated accordingly.
Genetic screening
For couples carrying genetic disease genes, gene screening can be carried out before IVF, and healthy embryos can be selected for transplantation to reduce the risk of abortion caused by genetic factors.
Good living habits
It is very important to reduce the risk of miscarriage by quitting smoking, drinking, avoiding drug abuse, keeping a reasonable schedule, and avoiding excessive physical activity and stress.
Regular prenatal inspection
Once the pregnancy is successful, it is very important to have a regular prenatal examination. Through regular prenatal examination, we can find out whether the condition of the fetus is normal, find problems in time and take corresponding treatment measures.
Summary
The causes of IVF abortion include genetic factors, uterine factors, immune factors and lifestyle factors. In order to avoid IVF abortion, we can carry out a comprehensive health examination, carry out genetic screening, maintain good living habits, and conduct regular prenatal examination. Through these preventive measures, we can reduce the risk of IVF abortion and improve the success rate of IVF.
