Conjoined Twins and Facts
- They are always identical twins, which
also means they are the same sex. They are developed from one fertilized
egg which doesn’t complete the split.
- Conjoined (aka Siamese)
twins are a very rare complication with identical twin pregnancies,
occurring in about 1 in every 200,000 pregnancies.
- It is 70% more likely that
conjoined twins will be female. Female babies are much stronger than
male babes. Although males twins are more likely to conjoin the female
sets are more likely to survive.
- The earliest documented
twins who were conjoined are brothers from Armenia and dates back to 945
AD. The brothers were connected the waist to the abdomen. During an
attempt to separate the boys one dies and the other died 3 days later.
- Another set of twins who
were connected at the hip and shoulder, are considered one of the more
famous documented twins, Mary and Eliza Chulkhurst. They were from Kent,
England and became known as the Biddenden Maids. They lived until the
age of 34.
- The phrase Siamese Twins
come from the famous twins, Chang and Eng Bunker from Thailand (which
was called Siam at the time). The brothers became famous before marrying
and settling down in the United States. The expression Siamese Twins now-a-days is viewed as inappropriate.
- About 50% of conjoined
(siamese) twins are stillborn and 35% only survive for the first 24
hours. And 5 – 25% of all will survive.
- In modern times, the first
conjoined two (who were conjoined at the lower back) that were
separated successfully was Caroline and Catherine Mouton from Louisiana.
Born in 1953 and at only 8 days old they were separated with both girls
surviving. The actual first ever successful separation is said to be in
the year 1689 of females joined by a ligament only 4.7” wide.
- There is no documentation to
suggest conjoined triplets or more have ever existed. The possibility
of a parasitic twin along with conjoined would be more likely.
- This is not preventable and there is nothing the mother has done wrong.
- Joined Twins are born all throughout the world and are not limited to any racial or ethnic groups.
