Why are multiple births more common after infertility treatments?

Short answer:
The treatments increase the number of viable eggs present in the female. The more eggs present, the more children possible.
Longer answer:
It should first be noted there are two types of multiple birth (or "twins"); "Identical" and "fraternal".
In a normal birth one egg is fertilized by one sperm and produces one child. If more than one egg happens to get fertilized, then more than one child is produced (commonly referred to as a fraternal twin).
In rare cases one egg may split after it has been fertilized; this becomes two (or more) identical twins. Identical twins have nearly matching DNA and from a genetic stand point are almost the same person on a biological level. (some tests cannot distinguish between them at all, the difference in DNA sequence often being less than a fraction of a percent)
With fraternal twins they do not share identical DNA. Fraternal twins are when more than one egg is fertilized and grow at the same time. From a genetic stand point these are clearly two different people. They share the same amount of DNA as normal siblings, but not the nearly matching DNA of an identical twin. On a biological level they honestly are not twins, they just happen to be born on the same day.
In regards to fertility treatments; the presence of more eggs from the treatment increases the odds of fraternal twins. This is pretty straight forward logic; if the presence of a normal amount of eggs typically produces 1 or more children than the presence of an even larger amount of eggs will increase the odds of even more children at once.
However the odds of identical twins is not increased. Basically the rarity of any one of those eggs splitting to become identical twins remains just as rare.
So while multiple births are more common, that is simply more eggs being fertilized at the same time because more are present; but none of them individually have any increased chances of splitting.

Does an educator have any infertility insurance coverage?
An educator is not any more likely to have infertility insurance coverage than any other worker. To understand why you have to look at state infertility insurance mandates. Typically most insurance plans will not cover infertility treatments unless forced to do so by law. Fourteen states have an infertility coverage mandate, but each state has varying rules and exceptions. The most common element is a rule that applies the mandate to employers with more than 50 employees. Most public school districts, colleges and universities employ more the 50 workers and may therefore be subject to the mandate. Thirty six states have no mandate, and since most educational institutions do not employ workers from multiple states they are subject to state laws from their home states. On the other hand, a private employer headquartered in a mandate state may export their infertility coverage to workers in non-mandated states. Your best bet is to understand your state's infertility insurance laws, and check with your employer and insurer before starting your infertility treatments.
Does medicare cover any fertility treatments?
If pregnancy, labor and delivery and well-care baby costs are covered by a mother on Medicare, then Infertility and Fertility Treatments such as IUI and IVF should be covered. Tax payers are paying for live births. If a couple if SUFFERING from the disease of infertility and/or structural damage or abnormalities that cause infertility, then A) Medicare should cover whatever it takes to fix the reproductive organ(s) in either the male or female (or both) or if all else fails, IUI or IVF should be covered. Everyone has the right to have a family. Couples that cannot concieve via natural means will most likely suffer from major depression and isolate themselves from places that remind them of what they cannot have naturally knowing that medical science is available to allow them the fairness to have a family. No discrimination comes from all angles. Medicare will cover maternity care for it's covered members. That is a slap in the face for couples that are infertile. Infertility is not very common. It is not that Medicare recipients are too poor to care for their children. Their taxes paid for their coverage when they were working. People get so depressed from multiple pregnancy losses, stillbirths and infertility that they get caught up in major depression that leads them to not be able to function like they used to. So YES. Medicare should cover infertility treatments at all levels. We all pay property taxes and not everyone has a child or children in school. Same thing.....

How common are twins?
Naturally conceived twins occur in approx. 1 in 89 births Identical twins are much more rare than fraternal. They occur in approximately 1 in 250 births. There are things that can increase your chances of having a multiple birth, including a mother being 30 or over when she conceives. For example, while there is a 3% chance of having a multiple birth at age 25-29, it increases to 4% at 30-34 years and almost 5% at 35-39 years. Other factors that can increase your chances of having twins include having a maternal family history of multiple births (fraternal), and of course, using fertility treatments (in vitro fertilization or fertility drugs). Your chance of having twins is also influenced by your race (multiples are more common in African Americans and least common in Hispanics and Asians), how many times you have been pregnant (the chance of having twins increases with each pregnancy), and whether or not you have had twins already.
