Guidelines on sperm DNA fragmentation testing [PDF]
Translational Andrology and Urology, 2017 Male factor subfertility is present in more than 50% of the couples treated with assisted reproductive techniques. Routine semen analysis provides information on semen volume as well as sperm concentration, motility, and morphology. Standardized methods have been published by the World Health Organization (WHO) (1).

Sperm DNA fragmentation assay by sperm chromatin dispersion (SCD): correlation between DNA fragmentation and outcome of intracytoplasmic sperm injection [PDF]
Reproductive Medicine and Biology, 2013 AbstractPurposeThe aim of the present study was to investigate the relationship between sperm DNA fragmentation index (sDFI) and outcome of intracytoplasmic sperm injection (ICSI).MethodsAll the patients were divided into two groups based on sperm DNA fragmentation analysis by the sperm chromatin dispersion (SCD) method. A total of 237 patients were in

The correct interpretation of sperm DNA fragmentation test [PDF]
Translational Andrology and Urology, 2017 We read the commentary by Dr. Ferlin with interest (1). The author first stated the drawbacks of semen analysis in the diagnosis of male infertility and the need for sperm function tests. It is followed by illustrating the limitation of the current evidence in supporting the routine use of sperm DNA fragmentation (SDF) testing in clinical practice.
