After becoming pregnant, women's bodies undergo certain changes, and pregnancy symptoms such as nausea, vomiting, dizziness, and tiredness may manifest over time. Pregnant women should engage in appropriate activities, avoid excessive fatigue, and avoid staying up late. The nutrition of the food they consume should be balanced to promote the development of the fetus. Some pregnant women may have two placentas, which indicate dizygotic twins, with one placenta corresponding to one fetus. Does having two placentas necessarily mean having twins of different sexes? Let's explore this further.

I. Does Having Two Placentas Necessarily Mean Having Twins of Different Sexes?

There is a 50% chance that having two placentas means having twins of different sexes. However, during early pregnancy, a chorionicity test is necessary during a B-ultrasound examination to determine whether the twins are dizygotic or monozygotic. Dizygotic twins are formed when two eggs are fertilized separately, while monozygotic twins occur when a single egg splits to form two fetuses, which will have the same sex.

II. What Does Having Two Placentas Mean?

Generally, having two placentas indicates dizygotic twins, with one placenta corresponding to one fetus. However, there are also cases of monozygotic twins with one fetus but the presence of an accessory placenta, which usually does not affect the fetus and therefore does not require concern.

III. Precautions During Pregnancy

During pregnancy, it is important to rest, avoid excessive fatigue, and consume fruits and vegetables rich in protein and vitamins to support the growth and development of the fetus and enhance the mother's constitution. Regular prenatal check-ups should be scheduled, and the fetal heartbeat and movements should be monitored to assess the condition of both the mother and the child. Special attention should be paid to twins, with increased nutritional intake and timely prenatal check-ups.
