High sperm abnormality rate is not necessarily a chromosomal problem, but may also be caused by unhealthy lifestyle, reproductive system diseases and other factors. 1. Chromosomes: For example, chromosomal abnormalities and gene deletions such as sperm mitochondrial gene and structural gene deletions may lead to abnormal sperm vitality, thus elevating the sperm malformation rate. 2. Unhealthy lifestyle: Bad habits such as stressful life, staying up late for a long time, smoking and drinking, and unbalanced diet may affect sperm vitality, thus leading to sperm deformities. 3. Diseases of the reproductive system: for example, varicocele may lead to obstruction of blood return to the testicles, thus causing pain and discomfort, as well as testicular hypoplasia, thus affecting the quality of spermatozoa and increasing the malformation rate of spermatozoa. If the malformation rate of sperm is high, the relevant examination should be improved in time to clarify the specific cause and then take targeted measures.
