Chromosome habitual abortion to be done

Habitual abortion in the academic known as recurrent spontaneous abortion, saying that more than two consecutive births occurred in the same pregnancy to stop the phenomenon of infertility or stillbirth, infertility is a scope for many common diseases affecting the outcome of pregnancy, the incidence rate of the total 1% of pregnancies, but in recent years on the rise.

 In the early abortion of the embryo. There are 60-80% is due to chromosomal abnormalities caused by abortion, about 33% of couples there is chromosomal abnormalities. Results of chromosome examination, common are the following:

 1, the chromosome balanced translocation.

 Doctor who were divided into 23 pairs of chromosomes, No. 1-22, and XX or XY. In the cytogenetic examination of different size, shape, structure and function is called a balanced translocation between chromosome translocation. Balanced translocation in general I do not occur in patients with deformities and mental retardation, but the carriers of both fertility and normal infants, birth can be balanced translocation carriers, birth defects or stillborn children, their chances of each 1 / 4, but also random, The latter two conditions often lead to abortion.

 Must pay attention to is that at least half of these abortions are caused by the husband. Because the fetus’s chromosomes half of the mother and the other half from the father. So his wife, abortion, the husband must do chromosome. Of such abortions are generally not promoted miscarriage. To be 16-20 weeks of pregnancy when the amniotic fluid of pregnant women to do chromosome examination, if found to be induction of fetal abnormalities, or else will be birth of deformed children with mental retardation.

 Second, homologous chromosome translocation.

 In short, homologous translocation is No. 2 with the translocation between chromosomes. This translocation to the embryo after fertilization by the formation of 100% abnormal fetus. Because more than one chromosome of the fetus can be born with severe dementia, all of which are deformed children: a small one chromosome fetus, in addition to X monomer addition, all stillbirth, therefore, homologous chromosomal translocation the only option in patients with infertility, to avoid the suffering of life.

 Third, the normal chromosomes.

 For the chromosome to do the normal need for further examination. Be noted that, although the husband and wife both normal chromosomes, but the fetus is also the possibility of chromosome abnormalities occur, since many early embryos due to chromosomal abnormalities caused by mutation. Chromosomes in the amniotic fluid of pregnant women not done so before the test, do not blindly Baotai in order to avoid low-quality child birth.
