Twins are a sort of multiple births, i.e., when a woman gives birth to more than 1 baby at the very same time. Twins occur when far more than one particular egg is fertilized or when the very same egg is fertilized much more than when by a single or two sperm, leading to formation of much more than one particular fetus.

Conjoined twins are identical twins who are joined together someplace in the physique. Conjoined twins are monozygotic twins, in the sense that they share the identical zygote. Often, they also share some essential internal organs. Formation of conjoined twins is believed to be the result of late twinning. When the twinning happens far more than twelve days immediately after fertilization of the egg, it could lead to formation of conjoined twins simply because the embryo could not split entirely. This might be due to genetic or environmental elements.

Conjoined twins are also known as Siamese twins, named following the well-known conjoined twins, Eng and Chang Bunker from Siam. Conjoined twin births are really rare, amounting to about one birth in each 1,00,000 births. Mary and Eliza Chulkhurst, famously referred to as the biddenden maids, are one particular of the earliest identified set of conjoined twins. The ratio of male and female sets of conjoined twins was discovered to be three to 1, and they are identified a lot more in certain countries like India or Africa.

Conjoined twins rarely survive because of the complexity of the bodies. Most of them are stillborn or die inside twenty-four hours immediately after birth. Conjoined twins can be separated surgically if none of the crucial organs are involved. There are various sorts of conjoined twins, depending on the part of the body where they are joined. These are cephalopagus, craniopagus, craniothoracopagus, dicephalus, iscopagus, omphalopagus, parapagus, pygopagus and thoracopagus. There are also some rare sorts of conjoined twins, such as parasitic twins (where a single twin is not completely formed and depends on the other twin to sustain life), and fetus in fetu (where one twins fetus is present inside the body of the other twin).

Some folks consider separation of conjoined twins as unethical if it includes death or disability of a single of the twins. Conjoined twins, if they survive, can lead healthy lives. There are instances exactly where conjoined twins have even married and turn out to be parents. The popular Siamese twins, Chang and Eng Bunker, fathered twenty-1 children in thirty-one years. ways to get pregnant fast how to make twins baby how to be pregnant
