Figure 2From: Efficacy of hyaluronic acid binding assay in selecting motile spermatozoa with normal morphology at high magnificationSpermatozoa observed at high magnification (8400×). (A) Normal spermatozoa, (B-D)Abnormalityof nuclearform: spermatozoa with small or large oval nuclear forms (B), spermatozoa with wide or narrow nuclear forms (C), spermatozoa with regional shape abnormality of nuclear form (D), (E-F) Abnormalities in nuclear chromatin: spermatozoa with vacuoles occupying >4-50% of the nuclear area (E) spermatozoa with large nuclear vacuoles (> 50% of the nuclear area)(F).Back to article page
