Test tube baby is a widely accepted assisted reproductive technology among modern people. Although the process is very complex and the failure rate is high, many people have achieved their expected goals through test tube baby. So many people who are preparing to choose IVF want to know: what are the reasons why IVF is not successful?
1. Congenital infertility
There are many reasons for congenital infertility in patients, whether it is due to varying degrees of sperm abnormalities or different types of ovarian diseases, which can lead to a decrease in the success rate of in vitro fertilization. Due to the dysfunction of these reproductive organs, it can also affect the normal growth and development of fertilized eggs in the uterus, resulting in a decrease in fetal survival rate.
2. Chromosomal abnormalities
Chromosomes are an important component of genetic inheritance. When different types of abnormalities occur in chromosomes, it means that during the process of in vitro fertilization, the fetus will also have different types of abnormalities, and even the probability of deformities. So, chromosomal abnormalities also have a very high failure rate in the process of in vitro fertilization.
In addition to the above factors, the age of both partners and their physical condition are also factors that affect the success of IVF. Meanwhile, during the process of in vitro fertilization, the different types of reactions that occur in the body are also key factors that affect the developmental status of the fertilized egg in the uterus.
