Recently received a message from a sister, she was because of chromosomal abnormalities to do three generations of IVF, took 10 follicles, mixed into 5 embryos, embryos are sent to the sac, the result of all the sac failure! The whole army was destroyed without a single course of treatment, and it was very sad! I think the rate of embryo loss in the TEST custody sac is too high! Now that a new course of treatment has begun, I don't know if I should raise a sac!
I believe that many people have the same question, IVF sac embryo loss rate is so high, do I want to raise sacs in the end? With the continuous improvement of IVF technology, the sac raising technology has become more and more mature, and has been recognized by many infertile women. Raising sacs is actually a process of survival of the fittest, only excellent embryos can survive to the end, although the success rate of sacs has reached 80%, but also needs certain conditions to support.
Lab environment
The temperature, humidity, gas type, etc. of the petri dish are very high, and the hardware configuration of the hospital, the professional technology and clinical experience of the embryonic laboratory personnel also have very strict requirements, not all laboratories can meet this standard, so when selecting the hospital, it is necessary to pay attention to whether the hospital laboratory has the conditions for the sac.
The condition of the embryo itself
It is necessary to have good eggs and sperm, combined into embryos to have developmental potential, if the quality of the embryos is poor, they may not last until the third day and will be eliminated, and these embryos will generally produce a large amount of cell debris during the culture process. In general, the higher the quality of the embryo, the easier it is to form blastocysts, the higher the success rate of embryo transfer, and the success rate of IVF will also increase.
Do you want to keep a sac?
Young, well functioning of ovarian reserve, good response to gonadotropins, good embryonic development. Usually refers to age ≤ 35 years;
Those who have more than 4 D3 embryos, or who have leftover embryos after transfer or freezing;
Patients who are at high risk of multiple pregnancies or who have had serious obstetric complications due to multiple pregnancies;
Exclusion of factors such as endometriosis, previous repeated transfer of embryos in the embryo of the fissure stage and infertility;
Poor quality of previous repeated embryos, failure of embryo transfer at the cleft stage;
Those whose endometrium is out of sync with the embryonic development of the cleft stage;
To be diagnosed or screened for preimplantation genetics.
