Fetal termination may be related to men Fetal termination may be caused by male factor, female factor, fetal factor, etc. It is necessary to analyze the causes from various aspects. 1. Male factor: If the sperms have deformities or dysfunctions, or if the chromosomes of the sperms have abnormalities, it will affect the development of the embryo and cause it to become infertile. 2. Female factor: If the quality of the egg cells is not good, the endometrium is inflamed, or the woman herself has hypothyroidism and other diseases, it may lead to fetal growth restriction and result in fetal failure. 3. Fetal factors: If the chromosome of the embryo is mutated, it may cause the embryo to die, resulting in embryonic sterilizations. In the case of fetal failure, it is necessary to go to the hospital in a timely manner to clarify the cause of fetal failure, so as to prevent the same situation from occurring again in the next pregnancy.
