Sperm morphology analysis (strict criteria) in male infertility is not a prognostic factor in intrauterine insemination with husband’s sperm

To assess the prognostic value of strict sperm morphology analysis in intrauterine insemination with husband’s sperm (IUI) cycles performed because of male infertility. Prospective study. Academic tertiary hospital. Seventy-four consecutive couples subjected to 271 IUI cycles because of male infertility. Strict morphology analysis 1 month before the beginning of IUI following the criteria of Kruger et al. Pregnancy and no pregnancy couples were similar regarding strict normal forms (2.85%±2.07% versus 3.13%±2.63%), slightly amorphous forms, and the morphology index (11.79±6.06 versus 12.04±7.13). Pregnancy rates (PRs) were similar when normal forms were 4% (35.7%). The PR, although higher in the group with morphology index >10% (41.4%) than in the group 10% (50.0%) than in the group
