Chromosomes determine what kind of hair we have, whether we have single eyelids or double eyelids, and also have a decisive impact on intelligence. If there are problems with chromosomes, it can lead to serious illnesses in children born. Some people want to know the causes of male chromosomal abnormalities. Let's take a look together.
What are the causes of male chromosomal abnormalities
1. Physical factors
Physical factors refer to the radiation environment that humans are in, which includes both natural and artificial radiation. 2. Chemical factors
People are inevitably exposed to various chemicals in their daily lives, some of which are natural products and some are artificially synthesized. They are absorbed into the human body through diet, respiration, and skin contact, leading to chromosomal abnormalities.
3. Maternal age effect
When the fetus is around six months old, all oogonia develop into primary oocytes and enter the nuclear network stage from the early stage of primary meiosis. At this time, the chromosomes will undergo a second round of loosening and stretching, similar to the pre nucleus, and then maintain until ovulation during puberty.
4. Genetic factors
Chromosomal abnormalities may have a familial genetic predisposition, indicating a correlation between chromosomal aberrations and inheritance.
What are the symptoms of chromosomal abnormalities
1. Children with chromosomal abnormalities usually exhibit pathological features at birth, such as a round head, a low nose bridge, and a slightly open mouth. We hope everyone can pay attention to this.
2. The child is also shorter than a normal newborn at birth. As one grows older, this gap will become larger and more pronounced.
3. Some patients may have cataracts, congenital heart disease, or heart disease secondary to cerebral embolism and abscess, gastrointestinal abnormalities such as duodenal stenosis, unstable atlantoaxial joint, and intense exercise can lead to spinal cord compression. The incidence of myeloid and lymphocytic leukemia is higher than that of the general population.
Some male chromosomal abnormalities will not affect the next generation and can be treated with in vitro fertilization, but others cannot. Therefore, after knowing the causes of male chromosomal abnormalities, it is necessary to go to the hospital for a comprehensive examination to see if one's condition is suitable for having a child, and then decide whether to prepare for pregnancy.
