Chromosomal abnormality in men may be caused by genetic factors, drugs or environmental factors.
1. Genetic factors: some men can have chromosomal abnormalities due to their own genetic factors, i.e. parents are recessive carriers of chromosomal abnormalities.
2. Drugs: Men taking certain drugs can also cause chromosomal abnormalities, such as nitroimidazole antibiotics, antiviral drugs and so on.
3. Environmental factors: If men are exposed to long-term radiation, radiation in the work environment, it may also lead to chromosomal abnormalities.
There may be other reasons for chromosomal abnormalities in men, and patients need to consult a doctor in time for examination and early treatment.
