Why are twins induced at 38 weeks?
There is also an increased risk of stillbirth with advancing gestational age in otherwise uncomplicated twin pregnancies, which is why elective birth is recommended at 37–38 weeks gestation . Thus, complications to twin pregnancies are frequently seen and labour induction is often indicated.
What causes MoMo twins?
“Mono Mono twins are identical twins that share the same amniotic sac and placenta in utero,” says Elaine Moore, Charge Nurse at McMaster Children’s Hospital (MCH). They develop when an embryo doesn’t split until after the amniotic sac is formed.
What is the rarest type of twins?
Monoamniotic-monochorionic Twins These types of twins share a chorion, placenta, and an amniotic sac. This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords.

Khandelwal, Professor of Obstetrics and Gynecology at Cooper, explains: “Monoamniotic monochorionic twin gestations can be safely delivered by vaginal route with a similar success rate as in other forms of twin pregnancies.” She adds, “The improved outcomes for these pregnancies may not be due to route of delivery but …
Can Monoamniotic twins be different sexes?
Twins can be fraternal, identical — and in extremely rare cases — semi-identical. Later in the pregnancy, however, the woman’s doctors were surprised to see that the twins were a boy and a girl. Because identical twins share all of their genes, they can’t be of opposite sexes like fraternal twins can.

What does diamniotic monochromatic twin pregnancy mean?

Are monochorionic twins always identical?
Monoamniotic twins are identical twins that share the same amniotic sac within their mother’s uterus. Monoamniotic twins are always identical, always monochorionic and are usually termed Monoamniotic-Monochorionic (“MoMo” or “Mono Mono”) twins.
What is ‘Mono Mono’ Twin Pregnancy?
Mono Mono twins (Monoamniotic-Monochorionic or “Mo-Mo” twins) are always identical and incredibly rare (about 1 in 10,000 births). They will share both their amnions, chorions and placenta too. They only happen in about 1% of monozygotic (identical twins) pregnancies.
