Couples who undergo IVF**, when their sperm and eggs are successfully taken out of the body, will be skillfully operated by embryologists to help sperm and eggs smoothly combine and form high-quality embryos, we transfer the best of these high-quality embryos back into the woman's uterus, 14 days after the transfer, we take blood tests to conduct pregnancy tests, some of which are lucky to have a successful pregnancy, and some patients may face an unsatisfactory pregnancy outcome of implantation failure. What is the reason for this? Why do you transfer high-quality embryos but still can't get pregnant?
What are the requirements for a successful implantation?
First of all, as we all know, if the embryo wants to be able to implant successfully, these two conditions must be met: one is that the embryo should have good developmental potential; Second, women should have a healthy uterine environment.
The so-called "high-quality embryo" refers to an embryo that is in good shape and has outstanding developmental potential, while at the same time having relatively few fragments. High-quality embryos are an important guarantee of successful implantation, so why do we sometimes fail to implant even though very high-quality embryos are transferred?
Other causes of implantation failure are these aspects:
1. Factors related to uterine cavity
The uterus is the first origin of our human life, and it is also the key factor for the successful implantation of the embryo, a good uterine environment ensures the basis for the healthy development of the embryo, women with uterine fibroids or intrauterine adhesions and endometritis or endometrial polyps and endometrial thinness and other uterine cavity diseases, the implantation rate and implantation rate will of course be reduced accordingly when the IVF embryo is transferred.
2. Hydrosalpinx factors
The toxic substances in hydrosalpinx will not only harm our embryo itself, but also affect the contact between the woman's endometrium and the embryo, and eventually cause the embryo to implant failure.
3. Immune factors.
Abnormal maternal immune mechanisms have the potential to lead to rejection of the embryo by the woman's endometrium, which can hinder the implantation of our IVF embryos.
4. Coagulation abnormalities.
Some patients may have a problem of insufficient blood supply to the endometrium, and they may have thrombosis in the small blood vessels of the placenta, which will eventually make it difficult for the embryo to implant.
5. Psychological factors
Women who start the IVF ** cycle often have too heavy psychological and mental burdens, and pay too much attention to the outcome of IVF, therefore, inner anxiety and restlessness, anxiety, tension, and depression, these obvious bad emotions will cause endocrine disorders in patients, and may even cause the failure of embryo implantation. Therefore, it is important to know how to self-regulate.
