Twins & Triplets Facts & Trivia
Top 10 things you didnt know about twins!

1. The scientific study of twins is known as "gemellology." The word twin is probably derived from an ancient German word twine, which means 'two together.'
2.1 in every 32 children born is a twin (1 in 65 pregnancies results in a twin birth). Twins account for 1.5% of all pregnancies or 3% of the population.
3.The twinning rate has risen 50% in the last 20 years. This is attributed to an increase in maternal age, wider use of IVF and assisted conception and advancement of medical technology.
4. Fraternal twins do run in the family but only on the maternal line. If a mother herself is a fraternal twin, the chance of conceiving twins increases four-fold.
5. The rate for identical twins, or monozygotic, multiples is random and universal (no influencing factors) and occurs 1 in every 285 births. They are the same sex, have the same blood types, hair and eye colour, hand and footprints and chromosomes, yet have different teeth marks and fingerprints.
6. Mirror image twins account for about& ;25% of identical twins. Their hair falls in opposite directions, they have mirror image fingerprints and if one is right handed, the other is left handed.
7. Factors influencing the twinning rate include; Maternal family history of twins, mother's age, maternal height/weight, no. of previous pregnancies, race assisted conception.
8. Twins and multiples have been known to develop their own 'language' that only they understand. This 'twin talk' is known as cryptophasia or idioglossia.
9. The world's oldest twins were Eli Shadrack and John Meshak Phipps born on Feb 14 1803 in Virginia and died at the ages of 108 and 113 respectively. The chances of identical twins surpassing the age of 100 is 1 in 700 million.
10. The Yoruba tribe of Nigeria have the highest twinning rate in the entire world (3 sets of twins in every 19 births). The Nigerian people attribute it to their population's consumption of a specific type of yam. China has the lowest twinning rate with only 1 in 300 pregnancies resulting in a twin birth.
11. Older mothers have a higher chance of fraternal twins, 62% of twins are born to mothers over the age of 30.
12. Did you know that up to 22 percent of twins are left-handed. In the non-twin population the number is just under 10 percent.
13. Twin types and genders are oddly symmetrical. 1/3rd of all twins are identical, 1/3rd are the same sex fraternal and 1/3rd are male/female fraternal. Of the identical twins, half are male/male, and half are female/female. Of the same sex fraternal, half are male/male, and half are female/female.
14. Australia produced the world''s first test-tube twins in June 1981. They are also known for producing the world's first triplets and quadruplets.
15. Worldwide there are at least 125 million living multiples.

I know there ARE more than 10 here but Twins are just so interesting!

Top 10 things you didnt know about triplets!
  1. There were 149 sets of triplets born in the UK in 2006. 1 in 4973 pregnancies is a triplet pregnancy. The triplet rate in the used to be about 1 in 10,000 maternities but this figure almost quadrupled between 1970 to 1998 with the introduction of assisted conception techniques. This rate has fallen since 1998 probably due to the introduction of HFEA regulations restricting the number of embryos transplanted during an IVF cycle.
  2. Approx 1/3rd of higher order births occur spontaneously (naturally), 1/3rd following IVF or GIFT treatment and 1/3rd from ovulation inducing drugs alone.
  3. Fraternal triplets (tri-zygotic) are created when three eggs are released and each is fertilized by a different sperm
  4. Identical triplets (monozygotic) are created when only one egg is released and fertilized, but splits, and then one half splits again. Very rare
  5. Mixed triplets - two identical and one fraternal (a pair and a spare!) occur when two eggs are released and fertilized separately, and one of those fertilized eggs splits again.
  6. Identical triplets share 100% of their DNA, are the same sex, have the same blood types, hair and eye colour, hand and footprints but have different teeth marks and fingerprints.
  7. Over 90% of triplets and quadruplets are born prematurely and/or have low birth-weight& ;(34 weeks is expected triplet pregnancy length &; 1.8kg birth weight)
  8. We think the heaviest triplets on record in were born in 1914 to the McDermott family - the combined weight of the three babies was 24lb - each baby averaging 8lbs.& ;
  9. The UKs oldest triplets Doris Kingston, Alice Holmes and Gladys Caress ( June 12 1927, South Elmsall, West Yorkshire in 2007 they celebrated their 80th birthday)& ;
  10. A 1983 study revealed that a mother of six-month-old-triplets expends an average of 197.5 hours per week (out of a possible 168) between herself and paid/volunteer assistance, on the care of her children and home. This did not include a time allowance for mother to bathe, dress, sleep, eat, relax or talk with partner!
Phew, I'm glad I ONLY have twins!
