Classification

The most common form of multiple birth is twins (two babies), but cases of triplets (three), quadruplets (four), quintuplets (five), sextuplets (six), septuplets (seven), octuplets (eight), and nonuplets (nine) have all been recorded with all siblings being born alive. There have been pregnancies — but no known instances of live births — of decaplets (ten), undecaplets (eleven) or duodecaplets (twelve). Fraternal twin boys in the tub The term twin most notably refers to two individuals (or one of two individuals) who have shared the same uterus (womb) and are usually, but not necessarily, born on the same day. ... A triplet is a set of three items, and includes in particular: one of three babies in a multiple birth a preparation of opal as a gemstone, with a thin layer of opal backed with a dark material and covered with cap of clear quartz in poetry, a tercet (three... Identical Triplet Sisters A multiple birth results when more than one human baby is born from a single pregnancy. ... For information about actual quintuplets, see multiple birth. ... Identical Triplet Sisters A multiple birth results when more than one human baby is born from a single pregnancy. ... Nonuplets are a case of multiple birth, in which the mother gives birth to nine offspring. ...


There are two types of multiple births, fraternal and identical. Identical siblings arise where one egg is fertilised and the resulting zygote splits into more than one embryo. Identical siblings therefore have the same genetic material. Fraternal siblings result from the fertilisation and implantation of more than one egg, so fraternal siblings are not genetically identical. A human ovum An ovum (also oocyte, ovocyte, or loosely, egg or egg cell) is a female sex cell or gamete. ... A zygote (Greek: ζυγωτόν) is a cell that is the result of fertilization. ...


Causes and frequency

Multiple births can occur either naturally (the woman ovulates multiple eggs or the fertilized egg splits into two) or as the result of infertility treatments (several embryos are usually implanted to compensate for their lower viability). Infertility is the inability to naturally conceive, carry or deliver a healthy child. ...


In general, twins occur naturally at approximately the rate of 1/89 of singleton births, triplets at 1/89 the rate of twin births, and so on (Hellin's Law). However, for reasons that are unknown, the older a woman is, the more likely she is to naturally have a multiple birth.


The number of multiple births has increased over the last decades. For example, in Canada, between 1979 and 1999, the number of multiple birth babies increased 35%. Much of the increase can probably attributed to the impact of fertility treatments, such as in vitro fertilisation. Younger patients who undergo treatment with fertility medication containing FSH followed by intrauterine insemination are at particular risk for multiple biths of higher order. In vitro fertilization(AE) or fertilisation(BE) (IVF) is a technique in which egg cells are fertilized outside the womans body. ... Fertility medication may in a larger sense include any medication that enhances fertility, but in a specific sense consists of agents that stimulate follicle development of the ovary. ... Follicle stimulating hormone (FSH) is a hormone produced by gonadotropes in the anterior pituitary gland. ... Insemination is the introduction of semen into the genital tract of a female. ...


Risks

Recent increases over the last few years in the number of multiple births have also provoked concern over the risks to the fetus and also to the mother.


The greater the number of babies in a single pregnancy, the more likely they are to have a low birth weight, to be born prematurely and to consequently suffer medical problems. For example, in 1999, 53% of babies in multiple births were premature, compared to 7% of singletons. [1] (http://www.statcan.ca/Daily/English/011210/d011210b.htm) There is also a higher rate of stillbirths for multiples than for singletons. The expected result of pregnancy is the birth of a living child. ...


Virtually all obstetrical risks are increased for the mother during a pregnancy with multiples. As many multiple pregnancies today are the result of the use of fertility therapy, efforts are being made to reduce the risks of multiple pregnancy, specifically triplets or more, by limiting the number of embryos (embryo transfer) during IVF to 1 or 2. Also, methods are available to reduce the number of fetuses in a pregnancy with many (see fetal reduction). Embryo transfer refers to a step in the process of in vitro fertilization (IVF) whereby one or several embryos are placed into the uterus of the female with the intent to establish a pregnancy. ... Selective reduction (or fetal reduction) is the practice of reducing the number of fetuses in a multifetal pregnancy (i. ...


Cultural aspects

Certain cultures consider multiple births a portent of either good or evil. A North Korean tradition that states that triplets are 'lucky' has led to the seizure of all sets of triplets born in North Korea, apparently out of leader Kim Jong Il's fear that one may overthrow him in the future. Kim Jong-il (born February 16, 1942) has been the leader of North Korea since 1994. ...
