What else can I help you with?
Can identical twins have separate sacs and placentas?
Yes, identical twins can have separate sacs and placentas, which is known as dichorionic-diamniotic twins. This occurs when the fertilized egg splits into two embryos early in development, resulting in each twin having its own sac and placenta.
How does the development of twins with two sacs and one placenta differ from twins with separate placentas?
Twins with two sacs and one placenta, known as monochorionic diamniotic twins, share a placenta but have separate sacs. This type of twin development carries a higher risk of complications compared to twins with separate placentas, known as dichorionic diamniotic twins. The shared placenta in monochorionic twins can lead to potential issues such as unequal sharing of nutrients and blood flow, which may require closer monitoring and medical intervention during pregnancy.
How does the presence of twins in separate sacs but sharing one placenta impact their development and health during pregnancy?
The presence of twins in separate sacs but sharing one placenta can impact their development and health during pregnancy because they may be at a higher risk for certain complications such as unequal sharing of nutrients and blood flow. This can lead to differences in growth and development between the twins, potentially affecting their overall health and well-being. Regular monitoring and medical care are important to ensure the best possible outcomes for both twins.
Can you explain the unique characteristics and potential risks associated with twins who share one placenta but have two separate sacs"?
Twins who share one placenta but have two separate sacs are known as monochorionic-diamniotic twins. This type of twin pregnancy is considered high-risk because the twins may develop twin-to-twin transfusion syndrome, where one twin receives too much blood flow and the other too little. This can lead to complications such as growth discrepancies, organ damage, and even fetal demise. Monitoring and early intervention are crucial in managing the potential risks associated with this type of twin pregnancy.
What is the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
If you have twins in separate yolk sacs is this good?
yes
Does 2 sacs and one placenta mean fraternal twins?
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex
Can identical twins have separate sacs and placentas?
Yes, identical twins can have separate sacs and placentas, which is known as dichorionic-diamniotic twins. This occurs when the fertilized egg splits into two embryos early in development, resulting in each twin having its own sac and placenta.

The shared placenta in monochorionic twins can lead to potential issues such as unequal sharing of nutrients and blood flow, which may require closer monitoring and medical intervention during pregnancy.
Do twins need to be in the same sac to be identical?
No, identical twins can be in the same or separate sacs. Identical twins form when a single fertilized egg splits into two embryos. Whether they share the same sac or have separate sacs is determined by when the split occurs during development.
Twins who delevelop in separate amniotic sacs?
Twins who develop in separate amniotic sacs are known as dizygotic or fraternal twins. This means they were conceived from two separate eggs fertilized by two different sperm cells. Dizygotic twins can have different genetic makeup and are no more similar than siblings born at different times.
Can a woman have 2 amniotic sacs?
Yes, a woman can have two amniotic sacs, which typically occurs in the case of a multiple pregnancy, such as twins. Each fetus can develop in its own amniotic sac, a condition known as dichorionic-diamniotic twins. This situation allows each fetus to have its own space and fluid, reducing the risk of complications associated with shared sacs. However, not all twins will have separate sacs; some may share one, leading to different classifications of twin pregnancies.
If you are an identical twin do you share a bag of fluid inside the mothers womb?
That depends on the type of twins. Fraternal twins usually have separate amniotic sacs. Identical twins usually share the amniotic sac.
Issues if twins have only one placenta?
No. Two placentas indicates dizygotic twins which always has 2 amnions and 2 chorions. This is a common misconception. My own twins are identical, yet they had separate sacs and separate placentas that implanted on polar opposite sides of the uterus. DNA tested have proven their zygosity. Whether identical twins will have their own placentas is dependent upon when the egg split. In my case, the egg probably splip immediately after conception and conception likely took place in the fallopian tube.
Why would you have two amniotic sacs?
Having two amniotic sacs, known as a "double" or "dual" amniotic sac, can occur when a woman is pregnant with multiples (e.g., twins). Each fetus typically develops its own amniotic sac. This situation is more common in dizygotic (fraternal) twins than in monozygotic (identical) twins.
How does the presence of twins in separate sacs but sharing one placenta impact their development and health during pregnancy?
The presence of twins in separate sacs but sharing one placenta can impact their development and health during pregnancy because they may be at a higher risk for certain complications such as unequal sharing of nutrients and blood flow. This can lead to differences in growth and development between the twins, potentially affecting their overall health and well-being. Regular monitoring and medical care are important to ensure the best possible outcomes for both twins.
Do identical twins share the same amniotic sac?
It can be either. Sometimes they are in their own individual sac, and in other instances they share one amniotic sac.
