What does the male chromosome test check?

Both men and women have chromosomes in their bodies. If there are abnormalities in chromosomes, it will directly affect fertility. Therefore, before preparing for pregnancy, both men and women need to do chromosome tests. Few men know about the items included in male chromosome tests. Knowing the items of male chromosome tests can make adequate preparations before the chromosome test. What does the male chromosome test check?

Generally speaking, male chromosomes are mainly checked during premarital checkups, that is, after marriage and before having children, to check whether there are family genetic diseases and whether there are abnormalities in chromosomes that will cause deformities and developmental abnormalities in the next generation. Therefore, many problems can be discovered by checking chromosomes, and it is recommended to pay attention to monitoring the baby's condition at all times after pregnancy.

What are the causes of male chromosome abnormalities?

1. Physical factors

Physical factors refer to the radiation environment in which humans live, including natural radiation and artificial radiation. 2. Chemical factors

In daily life, people are inevitably exposed to various chemicals, some of which are natural products and some of which are artificially synthesized. People absorb these chemicals into the human body through diet, breathing, and skin contact, which then leads to chromosomal aberrations.

3. Maternal age effect

When the fetus is about six months old, all the oogonia develop into primary oocytes and enter the nuclear reticulation stage from the prophase of the first meiotic division. At this time, the chromosomes will relax and stretch for the second time, like the pronucleus, and then will maintain it until before ovulation in puberty.

4. Genetic factors

Chromosomal aberrations may have a familial genetic tendency, which indicates that there is a relationship between chromosomal aberrations and genetics.

What are the symptoms of chromosomal abnormalities?

1. Children with chromosomal abnormalities usually show pathological characteristics at birth, usually with a round head, a very low nose bridge, and a slightly open mouth. I hope everyone can pay attention to this.

2. Children with the disease are also shorter than normal newborns at birth. As they grow older, this gap will become larger and more obvious.

3. Some patients may have cataracts, congenital heart disease or heart disease-induced cerebral embolism and cerebral abscess, gastrointestinal abnormalities such as duodenal stenosis, atlantoaxial joint instability, strenuous exercise can lead to spinal cord compression, and the incidence of myeloid and lymphocytic leukemia is higher than that of normal people.
