Correlation analyses of sperm nuclear vacuoles and sperm parameters in infertile males with abnormal sperm morphology

Variable	Outcomes (%)	Correlation to NV (r)
Abnormal morphology	95.2±3.4	0.911**
CDs	27.6±8.4	0.436**
ERC	30.9±4.6	0.921**
Sperm SSB rate	11.7±5.2	0.889**

^**P<0.01. Data are presented as mean±s.d. r: correlation coefficient; NV: nuclear vacuole; CDs: cytoplasmic droplets; ERC: excess residual cytoplasm; s.d.: standard deviation; SSB: single-strand DNA break
