Whether or not a cochlea will miscarry after undergoing the test procedure needs to be judged according to the size of the cochlea and the individual’s physical condition, and it may or may not miscarry. If the cochlea is relatively small and there is no obvious discomfort, it usually will not affect the development of the fetus, and the possibility of miscarriage is small, but it is necessary to see a doctor regularly for review in the later stage to avoid affecting the development of the fetus. If the coelomic sac is relatively large, it may cause extrusion to the abdominal cavity and the fetus, and the gradual increase of the fetus during embryonic development may also cause bleeding, abdominal pain and other symptoms, which may lead to miscarriage. If the coelom has already appeared, before the IVF is not carried out, the coelom needs to be treated according to the severity of the coelom, and if necessary, the coelom needs to be removed in time.
