| *SC indicates spermatocytes; RS, round spermatids; and ES, elongating
spermatids. Two treated animals and 1 untreated control animal were examined
for each time point. Values are expressed as the mean percentage of tubule
cross sections showing a given stage of spermatogenesis ± the standard
deviation. Values were generated by counting 100 tubule cross sections within
5 nonsequential histological sections of each testis, and generating mean and
standard deviation using Origin 7.0 software |
