Embryonic chromosome triploidy may be incidental or hereditary, and requires specific analysis before a definitive diagnosis can be made. Whether embryonic chromosome triploidy is hereditary or not is generally considered to be possibly related to drug factors, dietary factors and environmental factors. The more common clinical symptoms of embryonic chromosome triploidy include mental retardation, fetal malformations and developmental abnormalities, etc., and even some newborns may die at birth, and these abnormal clinical symptoms are often incurable later in life. Therefore, embryonic chromosome triploidy is relatively harmful. It is recommended that pregnant women need to actively receive treatment during pregnancy, and if chromosomal abnormalities are diagnosed after relevant examinations, termination of pregnancy should be considered.
