Some interesting facts about twins...

pivf-8wk-usIn the world of Reproductive Medicine, and much to the delight of our Obstetrician colleagues, we are always looking for new ways to reduce the risk of twins and other multiple births. Multiple pregnancies significantly increase the risks of all sorts of complications for mother and baby. It was a nice change of pace when I came across this great blog entry from the Renee Jacques at the Huffington Post about some cool and interesting facts about twins. So here they are:

  1. Identical twins do not have identical fingerprints
  2. Massachusetts has the highest number of twin births in US, followed by Connecticut and third our state of New Jersey. Not surprising considering we have lots of couples going through IVF and other infertility treatments and a law mandating coverage.
  3. Mirror image identical twins have reverse asymmetric features.
  4. Identical twins are not completely genetically identical
  5. Moms of twins may live longer
  6. Tall women are more likely to have twins
  7. Women who eat more dairy are more likely to have twins.
  8. It is possible for twins to have two different fathers
  9. Twins interact with each other in utero
  10. Some conjoined (Siamese) twins can experience each others senses.
  11. 40% of twins communicate with their own language.

Genetics, epigenetics and IVF babies

ImageIt has been known for some time that couples suffering from infertility, including those who get pregnant using assisted reproductive techniques such as IVF, are more likely to have complicated pregnancies.: more high blood pressure, diabetes, miscarriages, preterm births and likely birth defects as well. This is true even with singleton pregnancies. What is not so clear is why this is so. Is it the patient population? Women who have infertility tend to be older and have more medical and metabolic problems. Is it the fertility medications such as clomid and injectables? Is it something in the process of IVF or IUI that causes problems? Researchers at Cedars Sinai Hospital in Los Angeles have received a large grant from the National Institute of Child Health and Development to help study the molecular events the underlie an early pregnancy after IVF. They will be looking at both genetics (the DNA in the chromosomes) and epigenetics (changes in gene expression that occur outside the chromosomes) to try to discover an explanation for these problems
