dichorionic การใช้

By performing an obstetric ultrasound at a gestational age of 10 14 weeks, monochorionic-diamniotic twins are discerned from dichorionic twins.
Dichorionic twins potentially have different hormonal environments because they receive maternal blood from separate placenta, and this could result in different levels of brain masculinisation.
Dichorionic twins either never divided ( i . e . : were dizygotic ) or they divided within the first 4 days . Monoamnionic twins divide after the first week.
Monochorionic twins occur in 0.3 % of all pregnancies . 75 % of monozygotic twin pregnancies are monochorionic; the remaining 25 % are " dichorionic diamniotic ".
There is some evidence that it affects the variance in IQ test findings among identical twins, that is, monochorionic identical twins display less IQ variance one from another than do dichorionic identical twins.
