Fetal arrest is defined as the cessation of embryo fertilization. After the first embryonic arrest, it is recommended to go to a regular hospital, or reproductive medicine center. Chromosome examination of both parties, male semen examination, uterine adnexa examination and so on can be carried out. After embryo termination and miscarriage, it is recommended to check the chromosomes of both spouses to see if there are any chromosomal problems. Male semen liquefaction time, semen volume, sperm morphology, sperm count and sperm viability should also be checked to assess male fertility. If there is a problem with the semen, aggressive treatment is recommended before considering the next pregnancy. In addition, embryo abortion can be associated with uterine malformations, organic uterine diseases, and ovarian function, such as uterine fibroids, endometrial polyps, and small follicle ovulation. So also do ovarian function and uterus and other tests. If there is no abnormality in the above tests, it is recommended to carry out a number of other tests, such as thyroid function test and infertility antibody, in order to clarify the cause of fetal arrest. Of course, it cannot be ruled out that in some cases, the exact cause cannot be found, and it may be the problem of the embryo itself, so you can try to conceive again after recuperating your body.
