The chart is a comparison of the proportion of HA-bound spermatozoa in three
groups of patients. Controls are an unselected population (n=15). Tubal factor
are normospermic males whose partner has a diagnosed tubal factor infertility
(n=10). Idiopathic are patients whose infertility diagnosis has not been determined
(n=12). Data are means with standard deviation. The asterisk delineates
significant differences (p<0.05)
