Correlation of sperm DNA damage with blastocyst formation: systematic review and meta-analysis
Middle East Fertility Society Journal, 2021 Background The routine semen analysis fails to detect sperm DNA damage which contributes to the majority of male factor infertility. Sperm DNA fragmentation test (DFI) measures the sperm DNA damage. Blastocyst formation is an important step in IVF ± ICSI.

Sperm DNA fragmentation: indication and uses [PDF]
Translational Andrology and Urology, 2017 If you really think about it, the microscopic portion of conventional sperm analysis relies on the same principles of light microscopy that have been present since Antony van Leeuwenhoek first saw sperm cells in the 17th century. Cell counts, motility, and cellular beauty (based on our idea of an ideal sperm) guide us on a daily basis.

Sperm DNA fragmentation testing: proceed with care [PDF]
Translational Andrology and Urology, 2017 The authors should be commended for their thorough review of DNA fragmentation and the clinical indications for testing. The basic science review of DNA fragmentation, oxidative stress, and its association with male infertility is detailed yet concise. The authors also present clinical scenarios to better illustrate the current role of evaluating sperm
