Sperm abnormality index refers to the number of defective sperm divided by the number of abnormal sperm, and the size of the index can be used to determine whether there are sperm abnormalities and fertility abnormalities in men. In clinical practice, the index is mainly obtained by testing the sperm coloring in semen. When the index is greater than 1.6, it indicates that the fertility rate of a man is relatively low and it is not easy for him to have children. When the index is less than 1.6, it is normal and men can usually have children. When the sperm abnormality index is high, it is related to inflammation of the genitourinary system, endocrine disorders in the body, or varicose veins, etc., so it is necessary to consult a doctor in time and complete the auxiliary examinations in order to clarify the cause of the disease, and then give the appropriate treatment by a professional doctor.
