Can Identical Twins Have Two Placentas?
Can Identical Twins Have Two Placentas? Monozygotic twins can be monochorionic or dichorionic, depending on when the split occurs. Occurs when two separate eggs are released from a woman’s ovaries and each is fertilised by two individual sperm cells. Both twins develop their own placentas and implant in the uterus, so are dichorionic (two placentas).
