Is it possible that my monochorionic diamniotic twins could be a boy and a girl?

Is it possible that my monochorionic diamniotic twins could be a boy and a girl?

Yes: Although it has long been held that monochorionic twins are always identical (monozygotic), there are rare reports of monochorionic/diamniotic twins that are non-identical (dizygotic). This is more common in pregnancies achieved through assisted reproduction (ivf), but is still exceedingly rare. Almost all non-identical twins are dichorionic/diamniotic. ...Read more

What is the average wt of 5 months old monochorionic diamniotic twin fetus in grams.?

5 months?: Obstetricians deal in weeks, not months. Assuming you mean 21-22 weeks, the expected fetal weight should be around 300-500 grams. Please specify question parameters if you need more details. ...Read more

Is monochorionic-diamniotic placenta twins mentaly and physically healthy at birth or after brith, I am 21weeks this type of prengnany now. Worried a?

Usually: That type placenta is associated with an identical twin pregnancy. Twin pregnancies are inherently more risky and the potential for complications is greater - but the vast majority deliver healthy and normal babies. Good luck. ...Read more

Does monochorionic diamniotic twin pregnancy mean that my babies are identical?

Does monochorionic diamniotic twin pregnancy mean that my babies are identical?

Yes: While the diagnosis may be suspected, it can only be confirmed by close examination of the placentas or genetic testing before/after delivery. Usually with early ultrasounds, we can be pretty sure about identical or monozygotic twins. It means that during very early embryo development, one embryo split into two. ...Read more

What is twins with two separate amniotic sacs a sign of?

Diamniotic Twins: Twins that have two separate amniotic sacs are called diamniotic twins. This usually means that they are fraternal twins (arise from two separate fertilized eggs) but in some cases they can be identical twins (twins form from a single fertilized egg that splits in the course of development). ...Read more

Serial Fetal Ultra-: Sounds will be done to look for Intrauterine Growth Restriction & other determinants of fetal well-being or lack thereof, especially in the smaller twin. IUGR can be from fetal, placental or maternal disorders. Depending on the timing & severity, other studies can be done both prenatally & after delivery in an infant who is Small for Gestational Age to search for genetic & other medical causes. ...Read more

Get evaluated: You need to see an ob/gyn and get evaluated. Your second twin is in very serious danger. A maternal fetal expert can advise you on what options are available. Best of luck. Lack of amniotic fluid suggests a problem with the kidneys or bladder. ...Read more

I have monochorionic diamniotic twins pregnancy (23weeks).I am taking iron tablets daily& my problem is that my hb is 9.2 now. How can I increase my hb?

No need to increase.: There is a u-shaped curve describing the relationship between perinatal mortality and maternal hemoglobin; the minimal risk for perinatal mortality is with minimum maternal hemoglobin of 9-11 g/dl. You can therefore, see that continuing your oral iron supplementation is all you need to do at this time. If your hemoglobin drops below 8.5 g/dl, you may want to increase your iron and red meat intake. ...Read more

I have diamniotic monochorionic pregnancy. Will it be a boy or a girl type or will it be same gender type?

Identical twins: Identical twins (also called paternal) created from one sperm fertilizing one egg to form one zygote which then divides into two separate and identical embryos. So it will be the same gender type and have all identical features. Congratulations on your happy news! ...Read more

My doctor said that my wife is having Monochorionic Diamniotic pregnancy, would like to know the pro's and con's. and good to continue or terminate?

Continue: Two babies, two sacs (amniotic) with one placenta. While ALL twin pregnancies are a higher risk than singleton pregnancies, I don't think that this in and of itself warrants consideration for termination based on risks. Of course, this is a very personal decision and one you must have peace about. Good luck! ...Read more

I have monochorionic diamniotic preganancy. Usually at which week chances for delivery? . My doctor asked to me to take complete bed rest.

I have monochorionic diamniotic preganancy. Usually at which week chances for delivery? . My doctor asked to me to take complete bed rest.

Unsure: The average gestational age for twin deliveries is 36 weeks. Your pregnancy should be monitored more closely because of the twins and especially due to the shared chorion. You should consider a second opinion in relation to the bed rest recommendation as current studies would not support that recommendation. Good luck with your twins. ...Read more

Is it ok to have twins in 5-6 week gestiona, one sac but no heart beats. Hcg levels, 51330 iu/ml and after two days it became 57396iu/ml is it normal?

Is it ok to have twins in 5-6 week gestiona, one sac but no heart beats. Hcg levels, 51330 iu/ml and after two days it became 57396iu/ml is it normal?

Probably not: The HCG should double in 2 days at that point in the gestation. The example you give had only a minimal increase. This does not sound like a viable pregnancy. ...Read more

Empty sac at 6w3d HCG was 30000, 48hrs later hCG was 50000. BO or too early to tell? Twins?

Empty sac: BO? The HCG rise in 48 hours was just over 66% which is a normal rise. One more beta-HCG in another 48 hours would be helpful to get a better sense of what is going on. Normal twin rise would be faster. Ultrasound done 7 days after the first one will solve the question. ...Read more

At 12 weeks scan the ultrasound technician saw that the baby has penetrated the empty sac of the vanishing twin. How can this be?

Had ultrasound at 6. 2 weeks one had heartbeat 122. Dr said was a twin other sac in ultrasound will I expel it empty sac or does it go away?

Dissolves: Commonly twin gestation turns into single one due to loss of one fetus. As long as this happens early, there is usually no consequences for the remaining fetus. The other one is reabsorbed. Usually this happens for a good reason, and may mean one is not healthy. You could not have prevented it or caused it either. Get followup U/S to make sure you baby is growing well inside you. Best wishes!! ...Read more

Early scan shows sac yolk and fluttering of baby hgc high, does baby usually be at other side of sac not next to yolk? Or is there poss twins?

Early scan shows sac yolk and fluttering of baby hgc high, does baby usually be at other side of sac not next to yolk? Or is there poss twins?

Twin ultrasound: In a twin ultrasound, there would be at least two fetal poles (future babies), two yolk sacs, and potentially two gestational sacs (the sac surrounding the baby). Beta HCG is extremely variable in early pregnancy. Typically a low number is more concerning. If there is reason for concern, your OB will continue to monitor by blood test and ultrasound. ...Read more

Fetus measuring 1.5 inches at 8 weeks. 1 yolk sac visible. Could it possibly be twins and only half of one was visible making it appear to be large?

Fetus measuring 1.5 inches at 8 weeks. 1 yolk sac visible. Could it possibly be twins and only half of one was visible making it appear to be large?

Unlikely: The fetus is much smaller than 1.5 inches at 8 weeks - although the entire fetal sac is much larger than the fetus itself. At 8 weeks there isn't much to see, but it's unlikely to be a twin pregnancy. ...Read more
