How likely is abortion caused by IVF?
As the gospel of infertile couples, IVF technology has successfully helped countless couples realize their reproductive dreams. Although IVF technology has a high success rate in the field of science and medicine, there are still some risks, including abortion. This article will elaborate on the possibility of IVF induced abortion from four aspects: embryo implantation, hormone therapy, cytogenetics and maternal and infant health.
Embryo implantation may lead to abortion
The early steps of IVF include culturing and testing multiple embryos, and then selecting the best embryos to implant into the uterus. In view of technical limitations and uncertainties, there is a certain failure rate in the process of embryo implantation, which may lead to abortion. In addition, problems such as poor implantation position and difficulty in embryo implantation may occur during implantation, which may also increase the risk of abortion.
Hormone therapy may cause abortion
Hormone therapy during IVF usually includes the use of ovulation promoting drugs to help promote the release of mature eggs from the ovary. However, the use of the drug may increase the risk of multiple pregnancy, which will lead to an increase in the rate of spontaneous abortion. In addition, factors such as dose and cycle regulation in hormone therapy may also affect the embryo and pregnancy results, thereby increasing the possibility of abortion.
Cytogenetics may lead to abortion
In order to ensure the genetic health of embryos, genetic testing of embryos is usually carried out in the process of IVF. However, cytogenetic testing cannot completely eliminate all potential genetic defects. Even after the screened embryos are implanted into the uterus, a small part of them may still have physiological abortion, because some unpredictable problems occur during the development of embryos.
Maternal and infant health may affect abortion rate
One of the key factors for the success of IVF is the health of mother and embryo. If the mother has chronic disease, abnormal uterus or abnormal immune system, it may increase the risk of miscarriage. In addition, in the process of IVF, the lifestyle of pregnant women will also have an impact on embryonic development and pregnancy results. Smoking, excessive drinking, long hours of work, excessive exercise and other bad habits may increase the risk of miscarriage.
In conclusion, although IVF technology has made significant progress in the medical field, there is still a certain risk of abortion. The failure rate of embryo implantation, the uncertainty of hormone therapy, the limitations of cytogenetics and the factors of maternal and infant health may all lead to the increased possibility of IVF induced abortion. Therefore, before IVF, couples should treat the success rate and risk rationally, fully understand the relevant knowledge, and actively cooperate with the guidance and management of doctors to improve the probability of IVF success.
