To assess the pregnancy outcome of IVF with intracytoplasmic sperm injection (ICSI) in couples with profound teratospermia (Kruger's strict criteria of zero). Retrospective analysis of 545 consecutive cycles of IVF/ICSI performed between January 2000 and January 2003. Tertiary care center. Of 545 IVF/ICSI cycles, 45 patients were identified with a semen strict morphology of 0 using Kruger's strict criteria. Ovarian down-regulation (Lupron) was followed by controlled ovarian stimulation exclusively with hMG. Embryo transfer was performed 2 days after transvaginal aspiration/ICSI. Pregnancy outcomes and newborn/infant status. Of 45 patients undergoing 54 treatment cycles, 21 patients were positive for pregnancy (38.9% pregnancy/cycle). No birth defects were noted at time of delivery and all infants had obtained appropriate developmental milestones at 1 year of age. Men with profound teratospermia (Kruger's strict criteria of zero) may achieve acceptable pregnancy rates after IVF/ICSI thereby alleviating the use of donor sperm in this group. Furthermore, no increased risk of birth defects is apparent in this small series.
