In the process of IVF, there are various problems that may lead to the failure of the IVF transfer, the most common reasons are embryos not sleeping, embryo biochemistry, chromosomal abnormalities and so on. In the face of this reason, many couples will show a blank face, what is the embryo not to bed? What are the causes of embryos not getting out of bed?
1, the spirit is too nervous
There are many reasons why the embryo does not sleep, the most common reason is because of the female mental over-stress caused, because the female reproductive system and the human cerebral cortex have a direct connection, once the cerebral cortex appears excessive tension, then it may make the endocrine system be greatly affected, and this situation will also greatly reduce the probability of conception, so that the embryo does not sleep.
2. Ovarian luteal insufficiency
Female ovarian corpus luteal insufficiency, but also one of the important reasons for the embryo not to sleep, in fact, women's ovaries will directly affect the reproductive function, when the ovarian corpus luteum function is incomplete, it will make the progesterone secretion insufficient, and then cause abnormal endometrium, the thickness of the lining is critical.
3. There is a problem with the uterus
When women have uterine problems, it will also affect the embryo's inability to bed and cause infertility, there are many common uterine problems, such as uterine cavity adhesions, endometrial binding, uterine dysplasia, endometrial polyps, effusions and so on.
4. Poor embryo quality
The quality of the embryos is poor, and it is more difficult to implant than normal embryos, especially the blastocysts, and if the zona pellucida cannot hatch, it is possible to not get out of bed.
5. Female autoimmune function
It is related to the immune function of the mother itself, and the successful implantation of an embryo has a lot to do with the immune tolerance of its mother. If the maternal immunity is too strong, it may cause the embryo to fail to implant.
