Will chromosome 21s be inherited?

There are chromosomes in the human body, but when chromosomal abnormalities affect normal physical health, it may cause the patient to have difficulty getting pregnant. Whether chromosome 21s is hereditary depends on the individual's physical condition. Generally, in vitro fertilization can be chosen for treatment, and the chromosomes must also be checked.

Why do we need a chromosome test?

Data show that about 40% of spontaneous abortions are caused by fetal chromosomal abnormalities.

Many women who have miscarried due to chromosomal abnormalities will ask their doctors the same question: why are they and their husbands both fine, but the fetus miscarries due to chromosomal abnormalities? In fact, there are many reasons for chromosomal abnormalities. So far, the medical community has not reached a very definite conclusion on this issue. However, most scholars believe that chromosomal abnormalities are related to endocrine disorders, especially in women of older childbearing age, which can easily lead to chromosomal abnormalities in their eggs. In addition, drug abuse, air pollution, food pollution, electromagnetic wave pollution, radiation pollution, etc. are also common factors leading to chromosomal abnormalities.

In addition, one or both spouses may have chromosomal abnormalities, but they are invisible, but they become visible when passed on to the fetus. In addition, we would like to remind all prospective parents that in cases of miscarriage caused by chromosomal abnormalities, the fetus cannot be saved. Even if it is saved, it will be a deformed fetus. Therefore, it is not advisable to blindly save the fetus, which will cause lifelong regrets.

To achieve eugenics and good parenting, it is particularly important to conduct chromosome examination during the physical examination of newlyweds. Through examination, physical abnormalities can be discovered in time, thus effectively controlling newborn birth defects from the source. If the chromosomal abnormality is caused by drugs, dietary pollution, electromagnetic wave pollution, etc., you can try your best to avoid it; if it is caused by male endocrine abnormalities, you should conduct a systematic examination to find out the specific cause and provide targeted treatment.

Chromosome examination is necessary for habitual miscarriage

Homologous translocation is a translocation between two chromosomes of the same number. This translocation results in 100% abnormal embryos formed after fertilization. Because all fetuses born with an extra chromosome will be severely demented and deformed, and all fetuses with one less chromosome, except for X monosomy, will be stillborn. Therefore, the only option for patients with homologous chromosomal translocation is not to have children to avoid lifelong pain.

Habitual miscarriage is academically known as recurrent spontaneous abortion, which refers to the phenomenon of fetal growth retardation or stillbirth occurring more than twice in a row within the same pregnancy. It falls under the category of infertility and is a common outcome of many diseases that affect pregnancy. The incidence rate is 1% of total pregnancies, but it has been on the rise in recent years.

In early miscarriages. 60-80% are caused by chromosomal abnormalities, and about 33% of couples with miscarriage have chromosomal abnormalities.
