An analysis of the phenomenon of multiple birth

A literary review on multiple pregnancies shows a study done on one set each of septuplets and octuplets, two sets of sextuplets, 8 sets of quintuplets, 17 sets of quadruplets, and sets of triplets. More about multiple births has been learned over the ages but more is still to be learned and tested by scientists.

Quintuplets occur naturally in 1 in 55, births.

Perinatal Indicator: Multiple Births

If two An analysis of the phenomenon of multiple birth are fertilized and one divides into two structures as in monozygotic twins, the birth of a pair of identical twins will be born along with a single infant.

Before the advent of ovulation-stimulating drugs, triplets were quite rare approximately 1 in births and higher-order births much rarer still. Multiple Births Definition The birth of more than one baby from a single pregnancy; for example, twins or triplets.

A change transpires early in the pregnancy that causes the development of identical twins. Symptoms usually begin early in the first trimester and include bleeding, uterine cramps, and pelvic pain. Additionally, some women may have symptoms that would indicate a miscarriage, although an ultrasound reveals a single baby in the uterus.

If the loss occurs within the first trimester, neither the remaining fetus nor the mother generally have clinical signs or symptoms.

Multiple births can arise in many different combinations of ways but the probability of giving birth to more than one child remains fairly constant when compared to the entire human race.

This average decreases for each additional fetus: This shows that stillbirth happens usually 3—5 weeks before the woman reaches full term and also that for sextuplets or higher it almost always ends in death of the fetuses.

These and numerous other combinations can occur as the number of infants involved increases. Today, with the availability of early ultrasounds, the presence of twins or multiple fetuses can be detected during the first trimester.

That way, the risks for the mother and fetuses are decreased. The odds of having identical triplets is unclear. Abnormalities that result in the vanishing twin appear to be present from early in development rather than from a sudden occurrence.

Risks include preeclampsia, iron-deficiency anemia, uterine rupture, premature rupture of membranes, preterm birth, need for operative delivery, postpartum hemorrhage, and postpartum depression.

Vanishing twin syndrome has been diagnosed more frequently since the use of ultrasonography in early pregnancy. Brown University Assisted reproductive technologies are not the only cause of multiple births, a new study reports.

If the cell divides into four of five structures will then cause the pregnancy of identical quadruplets or quintuplets. Using CDC data from tobefore assisted reproductive technologies were available, the researchers found that by the time white women reach age 35, they are about three times more likely to have fraternal, non-identical twins.

Recent history has also seen increasing numbers of multiple births. There have been cases of human pregnancies that started out with ten, eleven, twelve or fifteen fetuses, but no instances of live births. If the fetal death is in the second or third trimester, the pregnancy may be treated as high-risk.

Quadruplet births are becoming increasingly common due to fertility treatments. Risks[ edit ] Premature birth and low birth weight[ edit ] Babies born from multiple-birth pregnancies are much more likely to result in premature birth than those from single pregnancies.

For reasons that are not yet known, the older a woman is, the more likely she is to have a multiple birth naturally. The birth of monozygotic twins takes place much differently than do the births of fraternal twins. Only as of the twentieth century have more than four all survived infancy.

And the percentage of these spontaneous multiples seems to be growing. Before the use of ultrasoundthe diagnosis of the death of a twin or multiple was made through an examination of the placenta after delivery. Quintuplets are sometimes referred to as "quins" in the UK [11] and "quints" in North America.

About one in eighty-seven births result in the birth of twins. The appropriate number of embryos to be transferred depends on the age of the woman, whether it is the first, second or third full IVF cycle attempt and whether there are top-quality embryos available.

Twins can be fraternal, also known as dizygotic twins, or identical, also called monozygotic twins, with the birth of identical twins being the rarest, occurring about four times in every thousand births, about one-forth as often as the birth of fraternal twins.

Vanishing Twin Syndrome

Fraternal twins are most common among black African followed by people of European origin. Other forms of multiple births such as triplets, quadruplets and quintuplets, occur very similarly to the birth of twins. The doctor identifies two fetuses, and the woman is told she is having twins.

The birth of twins can occur in two different ways, the fertilization of a single egg or the fertilization of two eggs.

These births are a rare event, occurring only about one in every fifty-thousand births.Using examples from this tragic play, you will learn. an analysis of economy problem While there are different an analysis of an example of foreshadowing in hamlet motivations for. · Get an answer for 'In act one scene four of Hamlet, where do you see foreshadowing An analysis of the phenomenon of multiple birth if any and can.

Furthermore, among multiple births, the risk of preterm births has also increased. These 2 trends contributed almost equally to the rise in or the stabilization of the overall preterm delivery rates. Multiple births also had an impact on the trends in low birthweight, mainly because of increasing numbers.

Multiple birth surge. To find out how much of this surge in multiple births is the natural result of women choosing to have children later in life—as compared to assisted reproductive technologies, to which people most commonly attribute the phenomenon—researchers analyzed Centers for Disease Control and Prevention (CDC) birth data.

Their findings appear in the journal Obstetrics & Gynecology. Adashi. A multiple birth is the culmination of one multiple pregnancy, wherein the mother delivers two or more offspring. A term most applicable to placental species, multiple births occur in most kinds of mammals, with varying frequencies.

The birth of three or more babies from a single pregnancy is called a higher order multiple birth. Why Does This Matter?
