Is it meaningful to check the chromosomes of the embryo?

Pregnancy is a particularly important thing for women. It represents the arrival of a new life and also brings more surprises to the family! However, pregnancy is not as smooth as everyone imagines, especially in the late stages of pregnancy, when accidents are prone to occur and miscarriage may occur if you are not careful. If a bad situation really occurs, examinations must be done, such as checking the embryo's chromosomes. So is this examination meaningful?

Is it necessary to check the chromosomes of the embryo after abortion?

Spontaneous abortion requires embryo chromosome examination. Only in this way can the cause be found out and the correct treatment method be adopted. It is also recommended that patients with spontaneous abortion must go to a regular hospital for regular examination and treatment in their daily life.

If embryonic arrest occurs frequently, it is best to find out the cause. Chorionic villus sampling can determine whether the embryo has chromosomal abnormalities. In addition, it is recommended that both husband and wife should go to the hospital for a pre-pregnancy eugenics check before getting pregnant. Genetic counseling is also required when necessary. Eliminate adverse physical factors and ensure safe conception to avoid similar situations from happening again.

Who should undergo chromosome testing after abortion?

1. People with reproductive dysfunction

Among couples with reproductive dysfunctions such as infertility, multiple miscarriages and teratogenesis, at least 7% to 10% are carriers of chromosomal abnormalities. The carriers themselves often do not suffer from the disease, but may suffer from reproductive dysfunctions such as infertility, miscarriage and teratogenesis due to chromosomal abnormalities in their germ cells.

2. People with abnormal secondary sexual characteristics

It is common in women. If there is primary amenorrhea, gonadal dysgenesis, accompanied by short stature, cubitus valgus, shield chest and slightly low intelligence, less or no pubic hair and axillary hair, low posterior hairline, infertility, etc., X chromosome abnormality should be considered. Early detection of these abnormalities and appropriate treatment can improve secondary sexual characteristics to a certain extent.

3. Those with hermaphroditic external genitalia

For patients whose external genitalia are unclear and whose gender is difficult to determine based on their genital appearance, examination of sex chromosomes can help make a clear diagnosis.

IV. Children with multiple congenital malformations and mental retardation and their parents

Common clinical features of patients with multiple malformations and mental retardation include: small head, wide-set eyes, low-set ears, short neck, cleft palate, hypotonia or hypertonia, epilepsy, palms perineum, anal atresia, short stature, small palpebral fissures, persistent neonatal jaundice and obvious livedo, heart malformations, kidney malformations, iris or retinal defects, etc. Chromosome examination can reveal abnormalities such as trisomy 21 and cry-a-cat syndrome.

Is it necessary to check the chromosomes of the embryo after miscarriage? The chromosome test of the embryo can show whether the chromosomes of the fetus are normal. It is best for couples with a history of multiple miscarriages to undergo a chromosome test for both spouses. If one of the spouses has chromosomal abnormalities, it can easily cause miscarriage of the embryo.
