Twins in the Womb | National Geographic

The video discusses the development and monitoring of identical twins in the womb during pregnancy, highlighting the following scientific concepts and observations:

• At 13 weeks gestation, twin fetuses begin to look more human, with eyes moving closer together and heads becoming proportionate to their bodies.
• By the end of the first trimester, most pregnant women undergo their first ultrasound to check for normal fetal development.
• ultrasound imaging, including 4D scans, can confirm whether twins are identical by identifying a single placenta and a characteristic dividing membrane (T-section).
• Interaction and movement between twins can be observed in the womb.
• twin pregnancies require closer medical monitoring due to higher risks such as premature birth and underdeveloped lungs and organs.
• These complications increase the likelihood of cesarean delivery, with twins being about 50% more likely to be born via C-section compared to singletons.
