The average percentages of sperm with intact acrosomes in eight batches of frozen-thawed semen from each of 17 bulls were compared with the non-return rates to artificial insemination by these bulls achieved over a period of three years. Despite the fact that the bulls could be categorised into three statistically significantly different groups according to their non-return rates, there was no significant correlation between the percentage of intact acrosomes and the non-return rates of the 17 bulls.
对17头公牛各自的八批次冻融精液中顶体完整的精子平均百分比，与这些公牛在三年期间人工授精后的返情率进行了比较。尽管根据返情率可将这些公牛在统计学上显著分为三个不同组，但17头公牛的顶体完整百分比与返情率之间并无显著相关性。
