Can Monochorionic Twins Be a Boy and a Girl?

Single chorionic twin pregnancy is generally not a case of a boy and a girl twin, and this condition is likely to be a case of monozygotic twins, which means the twins have the same gender. The two fetuses will grow in the same gestational sac, derived from a single fertilized egg that splits, and are not a boy and a girl twin. Single chorionic twin pregnancy refers to the growth of fetuses within a single chorionic sac and two amniotic sacs. This may occur after the fertilized egg successfully implants and develops, and during this process, another fetal heart and fetal bud splits out and grows and develops locally. Moreover, this condition is mostly monozygotic twins, with the two fetuses having the same gender. It is recommended to consult a professional doctor for effective examination. During pregnancy, special attention should be paid to dietary adjustments, and nutritious foods should be consumed to promote fetal growth and development. Regular prenatal check-ups should also be conducted at the hospital. If during pregnancy, a double chorionic twin pregnancy is diagnosed during a hospital examination, it could be a boy and a girl twin or twins of the same gender, depending on the actual situation. This condition is usually formed by the combination of two eggs and two sperm.
