Sperm DNA integrity test is a test to assess the chromosomal integrity of the spermatozoa, mainly to see if there is any fragmentation inside the spermatozoa of the semen and to test the quality of the spermatozoa. Sperm DNA integrity mainly refers to the fact that the chromosomes of the spermatozoa are functioning normally, the chromosome structure is intact, and there are no breaks in the DNA strands to disrupt them, as well as the production of corresponding fragments. If the DNA integrity of sperm is damaged, it may lead to abnormal function of sperm, which may cause oligospermia, azoospermia, or even male infertility. If the result of sperm DNA integrity test is abnormal, it is recommended to consult a doctor in time for a clear diagnosis and targeted treatment or therapy to avoid delaying the condition.
