Apply These Secret Techniques To Improve Pregnancy Loss And Chromosome Testing For Miscarriages

Although most couples are blissfully unacquainted with the statistics surrounding miscarriage, pregnancy loss is really quite common, with 10-25% of recognized pregnancies ending in miscarriage. For those who have suffered a pregnancy loss or are in the process of experiencing a miscarriage, you might be wondering what caused the loss and worry about whether it’ll happen again. This short article aims to answer the next questions:

Causes of Miscarriage

There are many different reasons why miscarriage occurs, but the most typical cause for first trimester miscarriage is really a chromosome abnormality. Chromosome abnormalities – extra or missing whole chromosomes, also called “aneuploidy” – occur due to a mis-division of the chromosomes in the egg or sperm involved with a conception. Typically, humans have 46 chromosomes which come in 23 pairs (22 pairs numbered from 1 to 22 and the sex chromosomes, X and Y). For a baby to develop normally it is crucial that it have the right level of chromosome material; missing or extra material during conception or within an embryo or fetus can cause a female to either not get pregnant, miscarry, or have a baby with a chromosome syndrome such as for example Down syndrome.

Over 50% of all first trimester miscarriages are due to chromosome abnormalities. This number could be closer to 75% or more for women aged 35 years and over who have experienced recurrent pregnancy loss. Overall, the rate of chromosome abnormalities and the rate of miscarriage both increase with maternal age, with a steep upsurge in women older than 35.

Pregnancy Loss – How Common could it be?

Miscarriage is far more common than a lot of people think. Up to one atlanta divorce attorneys four recognized pregnancies is lost in first trimester miscarriage. The opportunity of experiencing a miscarriage also increases as a mother gets older.

Most women who experience a miscarriage continue to get a healthy pregnancy rather than miscarry again. However, some women seem to be more susceptible to miscarriage than others. About five percent of fertile couples will experience two or more miscarriages.

Of note, the rate of miscarriage appears to be increasing. One reason for this can be awareness – more women know they’re having a miscarriage because home pregnancy tests have improved early pregnancy detection rates in the last decade, whereas during the past the miscarriage would have appeared to be just an unusual period. Another reason may be that more women are conceiving at older ages.

Types of Genetic Testing Helpful for Miscarriages

Genetic testing actually identifies many different types of testing that you can do on the DNA in a cell. For miscarriage tissue, also known as products of conception (POC), probably the most useful type of test to perform is really a chromosome analysis. A chromosome analysis (also known as chromosome testing) can examine all 23 pairs of chromosomes for the presence of extra or missing chromosome material (aneuploidy). Because so many miscarriages are due to aneuploidy, chromosome analysis on the miscarriage tissue can often identify the reason for the pregnancy loss.

The most common approach to chromosome analysis is called karyotyping. Newer methods include advanced technologies such as microarrays.

Karyotyping analyzes all 23 pairs of chromosome but requires cells from the miscarriage tissue to first be grown in the laboratory, an activity called “cell culture”. For this reason requirement, tissue that is passed at home is frequently unable to be tested with this particular method. About 20% or even more of miscarriage samples neglect to grow and thus no results are available. Additionally, karyotyping struggles to tell the difference between cells from the mother (maternal cells) and cells from the fetus. If a normal female result is available, it may be the right result for the fetus or it could be maternal cell contamination (MCC) where the result actually originates from testing the mother’s cells within the pregnancy tissue instead of the fetal cells. MCC appears to occur in about 30% or more of the samples tested by traditional karyotype. Results from karyotyping usually have a few weeks to months to come back from the laboratory.

Microarray testing is a new kind of genetic testing done on miscarriage samples; both most common types of microarray testing are array CGH (comparative genomic hybridization) and chromosome SNP (single-nucleotide polymorphism) microarray. Microarray testing is also able to test all 23 pairs of chromosomes for aneuploidy, but does not require cell culture. Therefore, you’re more likely to receive results and the outcomes are usually returned faster when microarray testing is used. Additionally, some laboratories are collecting a sample of the mother’s blood at the same time the miscarriage tissue is sent to enable immediate detection of maternal cell contamination (MCC).

Chromosome Testing – How can it help?

In case a chromosome abnormality is identified, the sort of abnormality found can be assessed to help answer the question: “Will this happen to me again?”. More often than not, chromosome abnormalities within an embryo or fetus are not inherited and have a minimal possiblity to occur in future pregnancies. Sometimes, a particular chromosome finding in a miscarriage alerts your physician to do further studies to research the chance of an underlying genetic or chromosome problem in your family that predisposes you to have miscarriages.

pregnancy Furthermore, in case a chromosome abnormality is identified it could prevent the dependence on other, sometimes quite costly, studies your doctor might consider to investigate the cause of the miscarriage.

Lastly, knowing the reason for a pregnancy loss can help a couple of start the emotional healing up process, moving at night question of “Why did this eventually me?”.

Chromosome testing can be especially important for patients with repeated miscarriages, as it can either give clues to an underlying chromosomal cause for the miscarriages or rule out chromosome errors as the reason behind the miscarriages and invite their doctor to pursue other styles of testing. For couples with multiple miscarriages determined to truly have a chromosomal cause, in vitro fertilization (IVF) with preimplantation genetic diagnosis (PGD) testing might be able to help increase their chances of having an effective healthy pregnancy.
