Figure 1 Sperm head retardance frequencies of the combined sperm sample (n = 486) from 63 patients. Mean ± SD sperm head retardance = 0.92 ± 0.25 nm and range = 0.40 nm to 2.38 nm.

Figure 2 Clinical pregnancies plotted against sperm head retardance where 0.91 nm or less cut-off value resulting from receiver operator curve analysis (Table 1) was considered optimal. In the clinical pregnancy group, significantly more pregnancies resulted from sperm with head retardance 0.91 nm or less (P < 0.05). NS = not statistically significant.
