These are 'monochorionic diamniotic' or MCDA twins. These types of twins share a chorion and a placenta but are in separate amniotic sacs. Using this method to determine chorionicity before 10 weeks gestation has nearly perfect accuracy. Di di twins are the most common type, don't have to be identical, and is most likely to be the easiest. A dichorionic diamniotic (DCDA) twin pregnancy is a type of twin pregnancy where each twin has its own chorionic and amniotic sacs.

This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords. This is the most common type. . These babies usually have different genetic material; approximately 10% will be identical. Split within 3-4 days after fertilization: When the fertilized egg divides before 3-4 days after fertilization then the twins are dichorionic/diamniotic. Additionally, a review of the English language literature was performed (PUBMED, PMC) using the search words monozygotic twins, dichorionic diamniotic, in vitro fertilization, and single embryo . For the purposes of the examination of the placenta, twins may be categorized as either dichorionic (each twin having its own amniotic cavity, chorion, and placenta) or monochorionic [twins sharing a chorion and placenta but having separate amniotic cavities (diamniotic) or a common amniotic cavity (monoamniotic)]. 32-33 weeks for MCMA twins.

Impact of fetal gender on prematurity has been primarily investigated in singleton pregnancies. In an attempt to understand better how fetal gender may affect gestational length in twin gestations after in vitro fertilization, same-sex twins and opposite twins were compared for pregnancy duration. This is medically called as being dichorionic-diamniotic (Di means two). All 1034 dichorionic and monochorionic-diamniotic twin pregnancies managed at Helsinki University Hospital area during 2006, 2010, 2014 and 2018 were collected from patient databases. 122, 123 One study reported a vaginal delivery rate of 83% when the first twin was presenting cephalic. 124 A large prospective study reported that planned vaginal .

There is a long-held credo, as illustrated in Langman's Medical Embryology (11th ed., Sadler, 2010), that dichorionic diamniotic (DD) twins develop after embryo splitting in the early stages of embryonic development. Of the dichorionic-diamniotic (DCDA) pregnancies reported at 7-9 weeks, 53 out of 54 (98%) were confirmed at the 11-14-week scan and one (2%) was found to be monochorionic-diamniotic (MCDA). .

Overall, it is considered that twin delivery should be around 37 weeks for dichorionic twins and 36 weeks for monochorionic twins. This means that each embryo has its own individual chorion (the outer membrane that develops into the placenta) and amnion (the inner membrane that fills with amniotic fluid and becomes the amniotic sac).

There were a total of 12 gender discordant twins (11%), 7 from the Day 2/3 transfers and 5 from Day 5 transfers. Fraternal twins occur when two separate eggs are fertilized by two different sperm at the same time, forming two separate embryos.
