So far, no studies have shown that the malformation rate of IVF is higher than that of natural fertilization.
IVF is a type of assisted reproductive technology, including in vitro fertilization-embryo transfer (IVF) and single sperm cytoplasmic injection (ICSI), which is a process in which egg cells and sperms are artificially fertilized outside of the body to form a fertilized egg that undergoes a brief period of development and is then transplanted into the mother’s body.
In general, IVF is used for women with severe tubal disease, endometriosis, and non-ruptured follicle syndrome, as well as for men with oligospermia, hypospermia, and dyszoospermia.
IVF is a relatively mature technology and there is no evidence that the fetal malformation rate of IVF is higher than that of natural fertilization. However, because IVF involves multiple steps, there is some chance of failure.
It is important to note that regardless of whether or not a pregnancy is conceived through IVF, it is necessary to go to the hospital regularly for a maternity test to screen the fetus for malformations to try to eliminate the risk of fetal malformations. In addition, women should avoid exertion after pregnancy, eat a balanced diet, and consult a doctor promptly if any discomfort occurs.
