What else can I help you with?
What DOES IT MEAN when you give birth and have 2 placentas in one sac but one featus?
Having two placentas in one sac but only one fetus typically indicates a rare condition known as a monochorionic twin pregnancy. It suggests that the pregnancy may have started as a twin pregnancy, but one embryo did not develop fully or was reabsorbed, leaving one fetus and two placentas. This situation can lead to unique risks and may require closer monitoring during the pregnancy to ensure the health of the mother and fetus.
Can one twin fetus be a full week behind the other twin fetus in the womb and survive?
Yes, that is very common.
Is there one placenta for twin horses one for each horse?
Twin births for horses are rare, especially when both foals are born alive. In this case there should be two placentas.
Is it possible if you abort one fetus and you were pregnant with twins would you then miscarry the 2nd twin?
If you were to miscarry one twin the other fetus can still survive, but the chances for that are SLIM!!
Do twins sharing one placenta have a higher risk of complications during pregnancy compared to twins with separate placentas?
Yes, twins sharing one placenta have a higher risk of complications during pregnancy compared to twins with separate placentas. This is because they may be more likely to experience conditions such as twin-to-twin transfusion syndrome, where one twin receives more blood flow than the other.
Can horses have twins and will they survive?
Yes they can produce twins, however, births of viable twins are actually quite rare about 4% of twin births result in 2 viable foals. Most mares in foal with twins will have one viable foal, or they will abort both twins because the two placentas will not support foals once they get to a certain size. Often, if there is a large difference in placentation between the two fetuses the smaller fetus will die and either mummify or decay. Mummification of one fetus will often allow the other fetus to develop to term. The production of identical twins is much rarer still.
Can a female fetus absorb her male twin fetus?
Yes, a female fetus can absorb her male twin fetus in a phenomenon known as "twin resorption" or "fetal resorption." This occurs when one twin is not viable and is gradually absorbed by the other twin or the placenta during early pregnancy. This can result in a variety of outcomes, including the surviving twin being born with some genetic material from the absorbed twin. However, this phenomenon is relatively rare and typically occurs in the first trimester.
Why is one fetus smaller than the other fetus in a set of twins?
It's not uncommon for one twin to be larger than the other twin in utero. The most likely cause of this is just that one twin is consuming more of the food and nutrition that the mother passes down to the babies. You could have one little piggy who's eating the other one's food. Since he is getting more food and nutrition that the other, he will be slightly larger, or heavier. There is not much concern over this as long as you are consuming enough food to feed them both. If the smaller one doesn't want all of his meal, then the larger one will take it. Another cause could be the position of the babies. One baby may have more room to grow while the other one might be a little constricted. Again, nothing major to be concerned. While it is common that one twin is smaller in development than the other, your doctor will still want to keep a check up on both of them to make sure the smaller one does grow at its own rate; and that the larger one doesn't get too large before delivery.
How many placentas do dogs have?
Dog puppies have their own placentas. If the litter is 4 pups, then there will be 4 placentas (afterbirths).
Do twins with the same placenta share any unique health risks or complications compared to twins with separate placentas?
Twins who share the same placenta may have a higher risk of certain health complications compared to twins with separate placentas. This is because they may be more likely to experience conditions like twin-to-twin transfusion syndrome, where one twin receives more blood flow than the other. It is important for twins with a shared placenta to be closely monitored by healthcare providers to prevent and address any potential complications.
What happens when one twin dies during pregnancy at 14 weeks What happens to the dead fetus?
The dead twin will be still-born and will have not effect on the remaining twin. You do need to speak to your OBY/GYN for more detailed advice.
What are the risk of having two placentas?
Having two placentas, known as a dichorionic pregnancy, can pose certain risks, especially if the pregnancies are in the context of twins. Potential complications include twin-to-twin transfusion syndrome (TTTS), where blood flow is unevenly distributed between the twins, leading to health issues for one or both. Additionally, there may be a higher risk of preterm birth and complications related to placental issues, such as placental abruption. Careful monitoring and management by healthcare providers are crucial in these cases.
