Semen parameters on the intracytoplasmic sperm injection day: Predictive values and cutoff thresholds of success.

Objective: This study was conducted to investigate the relationship of semen parameters in samples used for intracytoplasmic sperm injection (ICSI) with fertilization and pregnancy rates in infertile couples.

Methods: In this prospective study of Infertile couples with male factor infertility that had undergone ICSI, fractions of the same semen samples obtained for microinjection (to ensure the best predictability) were evaluated to determine the semen parameters and sperm DNA fragmentation index (DFI) on the day of oocyte recovery.

Results: In total, 120 couples completed the study and were subdivided into fertilized (n=87) and non-fertilized couples (n=33).
