Stained sperm morphology slides from an in-vitro fertilization programme were evaluated by the modified Williams system, the World Health Organization (WHO) system and morphometric size measurements (image analysis) to determine which system(s) were better predictors of fertility. Amorphous sperm head shape was the best predictor of fertility in both the modified Williams system and the WHO system, predicting the proper fertility status in 65% of the cases. Using only normal sperm in the… CONTINUE READING
