Biochemical pregnancy is a special type of miscarriage, one of which has the least effect on the body, because the embryo dies before it has begun to implant or has just begun to implant. 1 biochemical pregnancy may be accidental, 3 biochemical pregnancies basically mean that there must be a problem, 2 or more miscarriages or biochemical pregnancies can be called recurrent miscarriages, according to research data, patients with recurrent miscarriages are trying to get pregnant without any treatment, and the probability of recurrent miscarriages after pregnancy is 75%.
However, due to the large number of causes that lead to multiple biochemical pregnancies (recurrent miscarriages), doctors need to screen one by one according to the situation, and biochemical pregnancies can exclude a large number of maternal influencing factors because the embryos are not implanted or the implantation time is short.
Main causes of biochemical pregnancy with IVF transplantation:
1. Uterine cavity factors: Because the test tube is directly into the uterine cavity, without going through the fallopian tubes and other places, the situation of the uterine cavity is the most important for the implantation of the embryo, if there is a hydrops, polyps or adhesions in the uterine cavity, it will affect the implantation of the embryo, resulting in the emergence of biochemical pregnancy.
2. Hydrosalpinx: the water in the fallopian tubes will regurgitate back to the uterine cavity from time to time, patients often feel that there is a situation of intermittent vaginal fluid, after the embryo is transferred into the uterine cavity, the regurgitation of the fallopian tubes regurgitates back to the uterine cavity, causing the embryo to implant and take root before it is washed away; and the water in the fallopian tubes has toxic side effects on the embryo, and the embryo is blistered by the hydrops of the fallopian tube reflux for a long time, and it is possible to be poisoned by harmful substances inside, resulting in the emergence of biochemical pregnancy.
3. Embryonic factors: The quality of the embryo itself is not good, like a seed that cannot grow into a towering tree, planted in the soil, it has just sprouted, and life has come to an end.
Therefore, if there is such a situation of multiple biochemical pregnancies after IVF transplantation, you can stop and find the reason, because the sharpener does not mistakenly cut wood, and the factors affecting success can be more quickly pregnant after the factors that affect success are really solved.
