Decreased sperm fragmentation suggests an improvement in sperm DNA damage and it is recommended that the original treatment regimen be maintained to increase the likelihood of conception in couples with infertility. Sperm fragmentation refers to the percentage of sperm that are morphologically incomplete and malformed in relation to the total sperm content, and should be greater than or equal to 4% of all sperm in a normal adult’s semen expulsion. This test is mainly used to diagnose whether the sperm quality is normal or not, and is mostly applied to people with infertility. If the test indicates a reduction in sperm fragmentation, it suggests that the original treatment program is working well, and it is recommended that the original treatment program be maintained to help continue to reduce sperm fragmentation and improve the fertility rate of spouses with this condition.
