Objective

To investigate DNA fragmentation by using terminal deoxyribonucleotidyl transferase–mediated dUTP nick-end labeling in relation to World Health Organization parameters and computer-aided sperm analysis (CASA) in sperm to determine the possibility of obtaining a correlation among CASA parameters, sperm morphology, and DNA fragmentation.

Design

Sperm analysis according to World Health Organization parameters, terminal deoxyribonucleotidyl transferase–mediated dUTP nick-end labeling (TUNEL) for sperm DNA fragmentation, and CASA for sperm movement. Prospective study.

Setting

All the patients were under clinical management, consulting for hypofertility at a fertility center in France.

Patient(s)

One thousand six hundred thirty-three men who were referred for infertility investigation, including a complete sperm analysis.

Intervention(s)

Sperm analysis and DNA damage testing.

Main Outcome Measure(s)

Sperm morphology, DNA fragmentation, and movement characteristics.

Result(s)

One third of the patients had a TUNEL rate of >30%. Analysis of the 21 semen parameters tested revealed that 7 of them were significantly correlated with the TUNEL results.

Conclusion(s)

World Health Organization sperm parameters and DNA damage are complementary, rather than strongly linked. This should be considered to more fully understand the paternal contribution in assisted reproductive technologies failures.

Key Words: Sperm, WHO parameters, DNA fragmentation, TUNEL, CASA
