Statistical andrology: standard semen analysis and computer-assisted sperm motility analysis.
Results are reported of a statistical evaluation of the variables obtained by standard microscopic semen analysis and by computer-assisted sperm motility analysis. Descriptive statistical analysis and cluster analysis were carried out on both sets of data. A contingency table was created to compare the classifications obtained by the two clustering procedures. A canonical correlation analysis was performed to evaluate the classification power of the variables obtained by the two semen analyses. The results show that the two techniques of semen analysis are complementary and not substitutive and that the correlated variables "percentage forward motility" and "sperm velocity" are the most discriminating.
