Chromosome trisomy 10 has a certain probability of causing fetal arrest. Chromosome 10 trisomy is a rare autosomal abnormality, which is mainly caused by abnormal chromosome structure of parents, older age of women, smoking and alcohol abuse, pre-pregnancy medication, radiation, pollution and other reasons. Chromosome 10 trisomy has a certain probability of stopping the development of the embryo before it is formed, making it prone to fetal arrest and miscarriage, and seriously affecting the life span of the embryo. There is also a certain probability that it will lead to the appearance of unhealthy fetus, such as malformation, mental retardation, congenital heart disease and so on. Couples are advised to go to the hospital for checkups before getting pregnant, abstain from smoking, alcohol or taking stimulant drugs, etc., and follow the advice of professional doctors to prepare for pregnancy in order to prevent the occurrence of trisomy of chromosome 10. After getting pregnant, the couple should also undergo obstetric checkups on a regular basis to detect embryonic abnormalities in time and terminate the pregnancy at an early stage if necessary.
