Twin Dichorionic Diamniotic Placenta, Twin Monochorionic Monoamniotic Placenta
Austrian Registry on the Outcome of Monochorionic Pregnancies
About one third of twin pregnancies are resulting from a single fertilized oocyte. Two third of these monozygotic twins share a common placenta and are therefore called monochorionic.

- Trial name
- MonoReg (NCT03171909)
