It's normal for people to look at statistics in hopes of finding answers. The problem is, the statistics vary and there aren't always hard facts when it comes to this area. At the least, however, it's a guideline that provides some information about what's happened and the possibility of it happening again...
Generally Accepted Statistics--these are just a general guideline and should be viewed as such.
As much as 40 percent of unexplained infertility may be the result of immune problems
Generally Accepted Statistics--these are just a general guideline and should be viewed as such.
- Pregnancy loss accounts for about 10-25% of all pregnancies
- Women under the age of 35 yrs old are generally thought to have a 15% chance of miscarriage
- Women who are 35-45 yrs old are generally thought to have a 20-35% chance of miscarriage.
- There is either no elevated risk or just a slightly elevated risk (figured at 0-3%) for a woman who has had one previous miscarriage.
- Blighted ovums most likely account for the majority of all known pregnancy losses in the first trimester. Chemical pregnancies most likely account for the majority of all losses in the first trimester, however many women in this case will never even know that they have experienced had a loss.
- After a h/b is heard the chance of m/c is 4% or less.
- Chance of 2nd trimester m/c (before the 20 week mark) is 3%
- Chance of still birth after 20 weeks is 1%
- Chances of a ectopic pg is 2%, if no previous occurrences.
- After two miscarriages, however, the risk rises to 25%-30% (this seems to be averaged using no separation of maternal age)
- After three consecutive miscarriages with no live births, the liklihood of less is believed to be 30-45% (again, they did not analyze this by maternal age so by category this rate could be higher if based by age). Please note, there is still higher rate of expected success than expected failure.
