Doctors called these cases vanishing twins or vanishing twin syndrome (VTS). The tissue from a vanishing twin is mostly reabsorbed by the mother's body and the remaining baby.
What happens when one twin absorbs another? The vanishing twin's tissue gets absorbed by the surviving embryo(s) and the parent, too. This absorption process is completely harmless.
It's also called disappearing twin syndrome, and it happens when there's a loss of one baby in a multiple pregnancy. Usually it occurs early in pregnancy and involves the loss of one twin, while the other twin survives. The fetal tissue from the vanishing twin is usually absorbed by the mother and the surviving baby.
TTTS happens when there's an unequal flow of blood to and from identical twins who share a placenta. Sadly, one baby dies while the other survives and continues to develop for the remainder of the pregnancy.
Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple. The fetal tissue is absorbed by the other twin, multiple, placenta or the mother.
"Angel Baby," "Sunshine Baby," and "Rainbow Baby" are terms that refer to babies born just before or after another baby is lost due to a variety of reasons. They help immediate family members move through the grieving process and find meaning in the loss.
Sunrise baby: The twin who survives, if one twin is lost during pregnancy. Pot of gold baby: Any other babies born after a rainbow baby.
Like in all other types of miscarriage, the vanishing twin sadly cannot reappear. Vanishing twin syndrome is diagnosed more frequently these days than in decades past due to the use of ultrasound in early pregnancy: It's said to affect up to 30 percent of twin or multiple pregnancies, according to Kalish.
Chimerism occurs when a woman is pregnant with twins and one embryo dies, and the other embryo absorbs the twin's cells. (Scientifically speaking, this type of chimerism is called tetragametic because the baby was derived from four gametes – one egg and one sperm for each embryo.)
Studies suggest that vanishing twin syndrome occurs before the 12th week of pregnancy in around 36% of pregnancies with two fetuses, and in more than 50% of pregnancies with three or more fetuses.
Since ultrasonography and transvaginal sonography in early pregnancy, vanishing twin syndrome is more frequently diagnosed. Vanishing twin syndrome is evaluated to happen in 36% of twin pregnancies and in half of the pregnancies that begins with at least three or more gestational sacs.
The only apparent complication associated with disappearance of a twin was first-trimester bleeding. Apparently a vanishing twin need not adversely affect the development of a coexisting singleton pregnancy.
Identical twins originate from one egg cell that splits and gives rise to two embryos, but during development, one twin sometimes "vanishes," leaving only one baby to be born.
Death of one twin is associated with acute hemorrhage from the co-twin into the fetoplacental unit of the dead one. In the co-twin there is a 15% risk of death and ≥ 25% of the survivors have severe neurological injury. There is also a high risk (60-70%) of preterm birth.
Vanishing twin syndrome is the loss of one twin during pregnancy, usually in the first trimester, and oftentimes before the mother even knows she's carrying twins. When this happens, the tissue of the miscarried twin is usually reabsorbed by the mother's body over time.
Yes, it is possible to miscarry just one twin in pregnancies, and this can happen in the following conditions.
Also, breeding of animals containing human cells is prohibited in which such cells contribute to the development of reproductive cells such as sperm or eggs. Chimeric research not only raises ethical and moral issues but also raises concerns for the treatment and welfare of animals.
The twins, who are identical on their mother's side but share only part of their father's DNA, are the first case of semi-identical, or sesquizygotic, twins identified in Australia. They are the first worldwide to be diagnosed by genetic testing while still in the womb.
Twins often feel like they have a special connection, but for one California woman, the connection is particularly visceral — she is her own twin. The woman, singer Taylor Muhl, has a condition called chimerism, meaning she has two sets of DNA, each with the genetic code to make a separate person.
A parasitic twin is a type of conjoined twin where one fetus stops developing but remains attached to its twin. The other twin continues to develop, but is usually born with the limbs, organs or other tissue structures from its parasitic twin still attached. It's a very rare condition.

A womb twin survivor is someone who lost their twin or multiple anytime through pregnancy or shortly after birth; thus miscarriage, stillbirth, failed abortion, or neonatal death.
If this event happens in the first trimester of the pregnancy, the surviving twin will most likely develop without further consequences. However, if the fetal death occurs after mid gestation (17 weeks' gestation) there is an associated increased risk of preterm labor, IUGR, preeclampsia, and perinatal mortality [5,8].
The term is used in adoption as both “unicorn baby” and “unicorn birth mom”. A “unicorn birth mom” refers to a mother who is the ideal vessel to grow a child.
A golden baby is the baby that is born after a rainbow baby. This baby signifies the pot of gold at the end of a rainbow, and the luck parents feel at having two healthy babies in a row.
Monoamniotic-monochorionic Twins
This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords. If you have monoamniotic-monochorionic twins, your healthcare provider will monitor your pregnancy closely.
