Receiver operating curve. Receiver operating characteristic (ROC) curves to assess the specific proportion of headless spermatozoa that may be predictive of the following: oligozoospermia (intact sperm concentration < 15*106 spermatozoa/mL), asthenozoospermia (the percentage of intact normal morphology sperm< 4%), necrozoospermia (the percentage of intact live sperm < 58%) and teratozoospermia (the percentage of intact normal morphology sperm< 4%)
